Mal aire, a disease provoked by the accidental encounter with a spirit or by a cold wind, was cured exclusively with external treatments. Only one informant mentioned a particular fumigation treatment, which did not involve any plant: this consisted in burning a piece of clothes together with a grated piece of bull horn and standing in the smoke.

Malaria was commonly referred to as paludismo by the inhabitants of the community; its symptoms were described as high fever, shaking of the body, headache, pallor, absence of appetite. All the informants indicated the cause as the bite of infected mosquitoes. The plants indicated to cure malaria were always described as bitter and were often called shawetashi or shawetapini, which respectively mean bitter-leaf or bitter-herb.

Only two of the plants could be identified: Momordica charantia and Verbena officinalis. In reality, a greater number of plants were mentioned as a cure to malaria, but they have not been identified to species level. These included two taxa belonging to the genera Mikania and Hieraceum Asteraceae and taxa belonging to the families Asteraceae, Bignoniaceae, Euphorbiaceae and Lauraceae. Diarrhoea was very common and the informants believed that it was due to the excessive consumption of fruits or the mixing of sour and sweet food.

I think that the cause was most likely the lack of adequate sanitation system and consequent high bacteria content of the soil in the proximity of the households, where some crops were cultivated and where the children used to play with the soil.

The remedies for diarrhoea were all administered orally. Chacho is one of the diseases that I included in the popular belief system. It is considered a dangerous disease that occurs quite often and it might require the intervention of the curandero or the shaman. There are two form of chacho: chacho de cerro and chacho de agua. The first occurs when the forest of the hills does not permit tresspassing, or by falling asleep on a special rock in the forest. The second instead is provoked by the malevolent influence of spirits which reside in the water, usually in the river.

The symptoms are fever, vomit, headache and body pain. Headache was a common ailment, it was cured both with external applications and oral administrations. The cause of intestinal parasites was recognized in eating non-washed fruit and drinking non-boiled water. Intestinal parasites affected numerous adults and children. The majority of the remedies were administered orally. Each of them had a specific field of activity in relation to healing with medicinal plants: the first was a recognised shaman, the second was considered by many a curandero, a man who can cure, the third man was a tabaquero and the woman a vaporadora.

The characteristics of each of them are portrayed in Table 4. The three men were very difficult to approach: Carlos Camacho, the shaman, manifested adversion towards the ethnobotanical study from the very first meeting, but by the end of the fieldwork he invited me to visit his house and his medicinal garden, an event which will be described in more detail in the following section.

Manuel Herea was always very busy and therefore not available for interviews and Victor Andrs did not want to be interviewed. Rosa Violeta, the vapour healer, was living temporarily in another community in order to recuperate her health. I met her when she was taken back for few days in her house in the community, but she was really weak and could hardly talk, so I did not ask to interview her.

Her daughters explained that she became vapour healer through many years of practice and following a special diet. None of them became as good as her, because they were not willing to follow the strict diet. Another person who deserves to be given particular attention is the seora Flora, a lady aged 71, specialized in the field of midwifery.

She was not mentioned as much as the other specialists among the persons who knew most about medicinal plants, maybe because her main customers were colonos living in the town of Pichanaki. The indigenous women of the community instead usually gave birth with the assistance of their mother or husband. She explained that some colonos preferred to give birth at home in order to avoid the expenses of the hospital and hired her also because she could help women to give birth rapidly and without pain by using special medicinal herbs.

As far as she remembered, she had assisted in nine childbirths. She also told to have sold medicinal plants to induce abortion to colonos, but she did not want to do that anymore even if sometimes colonos where coming to try to buy such plants. Flora was the informant who recognised and described a medicinal application for the greatest number of medicinal plants on the forest track; it would have been interesting to see how many plants the shaman and the other specialists would recognise, but unfortunately this.

Portraits of the four persons considered most knowledgeable in the community from the results of the households interviews. He regularly relies on the drink Ayahuasca to diagnose and cure diseases and as a constant habit in the diet of a shaman.

He can transform into a jaguar or see through the eyes of other animals of the forest, especially birds, after drinking Ayahuasca. The medicinal plants that he uses, like the problems that people try to solve through him, are mainly related to social relations and include love charms and witchery. Many of his customers are colonos. Unfortunately she was not in the community during almost all the period of the fieldwork.

Her relatives had in fact taken her to stay in another village, in an attempt to cure her from an illness that they suspected had been sent by one of the other healing specialists. The cause was probably the envy towards her fame. In fact Rosa Violeta was very appreciated in the community and her treatments attracted also people from the nearby town.

She had been learning how to vaporear giving steam baths since she was young, following a particular diet that excluded salt and meat. Age: Many people described him as a man with an extensive knowledge on medicinal plants, others called him brujito little wizard , considering him capable to do witcheries. He did not confirm any of these details, but he showed a wealthy knowledge of the 80 selected medicinal plants I showed to him during the cross Age: 69 Name: Victor Andrs Gender: Male TABAQUERO Victor Andrs is one of the oldest persons in the community, one of those that do not speak Spanish maybe as a choise , specialized in curing with tobacco.

I never had the chance to meet him or talk with him, as he was mostly in his home and he did not want to be interviewed. His daughter and other informants explained that his way of healing included inhaling smoke from Age: A traditional tobacco healer is called sheripiari, from the word sheri, which means tobacco. Carlos Camacho defined himself a shaman and was also recognised as such by the rest of the community.

He had a wife but no children. In adult age he got interested in shamanism and travelled to several communities in order to acquire knowledge from local shamans and become one himself. He was very proud of his status, he said that he had been interviewed on television and his fame was going beyond the limits of the community, in fact the majority of his patients were colonos, people coming from the city.

During the first community meeting he said publicly that he was not going to collaborate with my research because in the past he had travelled in far away places and paid other shamans to get to know what he knew now and he did not want to share this with me, most of all because he suspected that I would make a profit from this information.

Nevertheless after I had spent two months in the community he seemed to be more. His wife poured some masato, a drink made of fermented yuca Manihot esculenta Crantz , in a bowl made of the emptied and dried fruit of tutumo Crescentia cujete L. The garden was different from those that I had seen in other households because the plants were cultivated in ordinate rows: there were a few different species of Pinitzi is the local term for herb and Ivenki Cyperus spp.

The two plants were planted next to each other and he said that one was for good luck and the other for brujera witchery. He saw me a little sceptical and he explained that the two plants were two separate organisms and therefore had different spirits and that he could get in contact with them and ask them to cure or help the patient.

There I understood that the cures given by the shaman were different from the remedies prepared by common people because they involved a spiritual connection with the plants. Also, the diseases and condition cured where somewhat mystical including discovering the mandatory of a witchery, mortal spells he said that he could but he did not do that , love charms and bringing good luck to business, among others.

By the end of our chat we went back to the front of the house where an Ayahuasca plant, Banisteriopsis caapi Spruce ex Griseb. Morton, was in bloom. The shaman told me that this was the Ayahuasca rosada pink , which was the most effective among three kind of Ayahuasca.

He added: this plant is like a woman, jealous like a woman: if I planted another one in my garden she would not talk to me anymore. He explained that when he drank the decoction of the liana he could see other places with the eyes of the birds of the forest that were his own children, fruit of his union with the Ayahuasca plant.

He added that through this union it was possible for him to cure patients using the power of the plant. At the end of our conversation he agreed to have a picture taken under the plant of Ayahuasca and for the occasion he wanted to wear his cushma and a wreath with coloured feathers that are usually worn for ceremonial purposes Fig.

During the interviews with the other villagers I got the impression that the relation to this man was not equal for all the people of the community: he was appreciated by some while feared. Envy towards the success of other people seemed to be the major force causing conflicts in the community. An event is here defined as the process of asking one informant on one day about the uses they know for one species Phillips and Gentry, a. Ethnobotanical information was also collected when the informants spontaneously described the medicinal use of plants that were not pre-marked, and this occurred in a total of events.

During the forest walks, the informants showed different degrees of knowledge of the tagged plants which I indicated to them along the way: sometimes they did not know the plant, other times they were able to name it but did not know any medicinal application for the plant, other times they knew one or several medicinal applications, and in this case in the great majority of cases they also described the preparation and way of administration.

The performances of men and women were compared by summing up for each gender the number of events in which a medicinal application was described on the track by each informant. In the analysis only the events in which the informant could describe the medicinal use of the plant as well as its preparation were counted. Women described a medicinal application in a higher number of events: they scored a total of records of use versus total records of use by men.

The difference is mainly given by the 72 pre-marked plants, of which women cumulatively provided records of medicinal use This means that women described one or more medicinal uses for the indicated plant in All the informants, with a varying extent, spontaneously pointed out at plants that were not pre-marked and described their medicinal application. The total number of additional plants indicated by the two genders is similar, being 91 for men and 96 for women Table 4.

Number of events during which a medicinal application was described by each gender. Women described a medicinal application in a higher number of events. Men 91 Women 96 Performance of the informants in the forest track No. Female informants identified and described the medicinal use of the pre-marked plants in more events than men. Both genders indicated also a number of additional medicinal plants.

In the group of men the oldest informant 55 years old was the most knowledgeable, indicating a medicinal use for 30 of the 72 pre-marked medicinal plants; also in the group of women the most knowledgeable informant was the oldest person 71 years old , who indicated a medicinal use for 57 of the 72 pre-marked medicinal plants. In the group of women two other informants aged 36 and 55 were particularly knowledgeable indicating a medicinal use for 49 and 52 of the 72 pre-marked medicinal plants each.

The reasons will be discussed in the next chapter. Total informants No. Men No. Number and percentage of plants that were known by each number of informants group during the forest walks. Of these fifteen plants, seven have been identified to species level and correspond to: Piper aduncum L. Gmelin and Xiphidium caeruleum Aubl.. For example the name Pituca selvaje, indicating a plant which is similar to the cultivated pituca Xanthosoma sagittifolium Schott.

In some cases the informants gave detailed information about the medicinal use and preparation of a plant, but they said that it had no name, they just referred to it as e. The indigenous names were often formed by a word that indicated the use of a plant or a characteristic of its morphology or its habitat, plus suffixes like pini and -shi, which mean respectively herb and leaf.

For example the names marankishi, maranketza, takre ki maranki indicated plants used against snake bites, from the Ashninka name for snake maranki. These were respectively Cyclopeltis semicordata Sw. Out of seventeen children in the class, two a boy and a girl declared that they would have liked to become shamans.

The class listed 27 medicinal plants with their respective uses and preparations. These are displayed in Table 4. The children were able to describe the way of preparation only on 14 of the 27 plants. As no voucher specimen was collected during this activity, the botanical name has been inferred from the vernacular name for those plants for which the vernacular name was uniquely used in the community.

For example several plants were called Amargn in the. He had in his garden a young plant of Ayahuasca Banisteriopsis caapi which he had taken back from one of this journeys and which he had used to cure a problem in his knee. This was the only case of self medication with Ayahuasca reported in the community. All the other informants attributed the use of Ayahuasca to be only in the domain of the shaman.

Another informant reported that she had travelled sometimes to communities located on the river Tambo and that she had obtained some very good medicinal plants in exchange for plastic utensils that were highly valued in those distant communities. She now cultivated these plants in her garden. In the course of various informal conversations, it was perceived that it was a common idea of many of my informants that the indigenous communities that lived more deep in the forest, meaning going towards the low land Amazonian region and at more distance from colonos settlements, had a greater knowledge on medicinal plants than them.

The purpose of the study was to document the use of medicinal plants in the community, but it is also interesting to contextualize and discuss these findings in a broader perspective, in which medicinal plants and knowledge about them can prove to be a strong tool for the indigenous community in its constant struggle for cultural liberty.

I will first discuss some of the ethnobotanical findings and afterwards discuss some of the broader perspectives. This result is in accordance with previous literature. Species belonging to these families are often targeted during taxonomic approaches to drug discovery because they are rich in secondary compounds like steroids and alkaloids. In particular, the families of Solanaceae and Rubiaceae contain several biodynamically active alkaloids Desmarchelier and Witting, The use of medicinal plants pertaining to the family Araceae is well documented in Brazil by Mors et al.

The family Asteraceae includes numerous species used to cure several diseases. Gupta describes the uses of 54 Ibero-American medicinal species pertaining to this family. Other families particularly rich in secondary compounds, which include some species known as medicinal in the community of Bajo Quimiriki, are: Apocynaceae, Bignoniaceae, Euphorbiaceae, Lauraceae, Malpighiaceae, Menispermaceae, Piperaceae Roth and Lindorf, The number of medicinal plants indicated by the informants in each family could also reflect the relative abundance of species of these families in the local flora composition.

I suggest that the medicinal plants are selected on the base of two factors: abundance and activity. Herbs represented the dominant life form of the medicinal plants used in the community. Tipically, the plant parts used were the leaves and the stem, mostly prepared as a decoction and administered orally. This has been reported elsewhere in Peru De-la-Cruz et al. In fact, the use of leaves and.

The 62 species that were identified where collected almost equally in the homegarden and in the forest, while a minor number was collected on the river banks. This result is biased by the fact that the numerous plants growing in the homegardens were also commonly known and reported in texts of medicinal flora of Peru which I consulted during the plant identification.

If it had been possible to identify all the plants indicated by the informants, it is very likely that a greater number would be provenient from the forest. The limited number of medicinal plants collected on the river banks can be explained with the minor plant diversity of the banks in comparison with that of the forest and of the homegardens.

The river banks were also mentioned during the household interviews as a minor source of medicinal plants. Some species were reported only by one informant Fig. This happened either when the plant was collected in the homegarden of the informant and not found elsewhere Fig. Nevertheless this information should not be necessarily disregarded as noise; as Kvist et al. Therefore the ailments treated in the community of Bajo Quimiriki with medicinal plants, are the same common ailments suffered by the majority of.

In the United States, for example, drugs are mainly used against microbial infections, nervous system affections, dermatology and cardiovascular diseases Cox, The relation between the specialists in the community was of strong competition, probably due to the rivalry among them to attract customers and make a profit using their knowledge. The shaman and the partera were working particularly with non indigenous customers, and this suggests that they might have developed their profession in recent years as a form of off-farm activity.

This could be one of the effects of the proximity to the city: the commercialization of local culture. It has been reported in Brazil, that young people acquired traditional ecological knowledge in order to work as eco-tourism guides Voeks, In the Baram District of Borneo instead, it was noticed by Brosius that the Eastern Penan, after a decade of intense visits and campaigns of environmentalists in the area, would discuss issues related to medicinal plants much more often than they did before having contact with the environmentalists.

The author thought that the new interest of the Eastern Penan towards medicinal plants had been influenced by the contact with western environmentalists. In the same way, the possibility that the shaman of the community of Bajo Quimiriki might have decided to specialize in this practice due to the possible economic returns from a clientele mainly composed by colonos should be considered. It should be remembered that he had started his apprenticeship at an old age, which is unusual, as it is variously reported that apprenticeship of shamans in the Amazonian region starts at a young age Schultes, ; Hvalkof, The apprenticeship also comports strict rules like celibacy, while the local shaman had a spouse and he had gained his knowledge looking for advice and paying for the information shamans of other communities.

The initial reluctance of the local shaman to provide information on the medicinal plants used by him should not be surprising; often in order to get to the necessary level of confidence and trust to be told this sensitive information a researcher should reside in the community for a long time. According to Cunningham , the specialist medicinal uses have a high sensitivity level, while household herbal remedies have a medium sensitivity level.

This is in accordance with the present study, where the ordinary users of medicinal plants where willing to share their knowledge, while the shaman and the tabaquero wanted to keep it secret. Also, the midwife, who gladly participated in the forest walks, indicated some pinitzi that she cultivated in her homegarden, which she did not want to share or divulgate to the community, while she was indifferent whether they would be known by outsiders.

Lidia, a female informant aged 36, would attend to the Mess and believe in the existence of God, while she also believed in the existence of an animated world, where spirits of the forest and of the river could affect the health of a person. Another informant instead had a different opinion: he said that he and his wife stopped attending the shaman and believing in spirits since they became Christian.

He said that before his conversion, he would also suffer from Mal aire or from other attacks from bad spirits of the forest, but he added that since he stopped believing in it, he did not experience this kind of illness anymore. This statement underlines the relation between local cultural beliefs and perception of illness. It has been proved that shamanic practices are very effective in curing psychosomatic illnesses Hvalkof, , this is probably due to the fact that the shamans usually have an estimated and socially important status within the community, fact which undoubtfully also influences psychologically their patients during healing practices.

This result has been widely reported in literature Phillips and Gentry, b; Shanley and Rosa, ; Voeks, This result underlines the vulnerability of ethnomedicinal knowledge to acculturation and is a powerful evidence of the importance of doing as much ethnobotany as possible, as soon as possible Phillips and Gentry, b. Nevertheless, the correlation was statistically significant if the whole group of informants was considered, while it was not significant if only the group of women was analyzed.

In order to explain the performances of the informants we should consider their personal backgrounds. Flora, the informant aged 71 who had the highest plant knowledge, was a midwife with a marked personal interest towards medicinal plants. She occasionally also sold medicinal plants to colonos. Lidia, the exceptionally knowledgeable young female informant 36 years old , was the elder daughter of the local vapour healer and she said to have.

She explained that when she was very young she wanted to become vaporadora too, but during adolescence she gave up the apprenticeship due to the rigid diet to respect. So, the personal background of this informant explaines her particularly high knowledge compared to her young age. This is also true for the main informant with whom the track was established and who provided information on all the pre-marked plants: he was 27 years old, brother of the actual leader of the community and son of the curandero described in Table 4.

He said that he was very interested in the use of medicinal plants and that in the future he might have considered becoming a curandero himself. So, although there is a general trend of acquiring medicinal knowledge through the age, much of the variation between informants can be explained by personal interests and also by the relation with a local healer.

For this reason I believe that the presence in the fieldwork of my husband facilitated the interviews with men, who were more open with him than with me. On the other hand, being female gave me the possibility of entering in the households and interviewing women with more facility, treating topics like women ailments without embarrassing the informant.

Moreover, the fact that I was in the community with my partner allowed us to have a private space, where we could be when we wanted to be alone to work, discuss about our daily impressions or just relax after a day of walks in the forest. This does not mean that the people actually harvest more plants from the forest, but that the forest hosts a higher number of potential medicinal plants.

In fact it was reported by some informants that they rarely walked to the forest in order to collect a particular plant. This is in accordance with the findings of Stagegaard et al. This is due to the fact that the shaman did not have a positive net of relations in the community. Many informants called him egoist because he did not want to participate in this study, and this situation automatically made them my allies, willing to participate and to translate, if necessary, what the elderly people in their family could tell about medicinal plants.

Another effect that was noted is that, after the speech of the shaman, people of the community demonstrated increased curiosity towards the future use of the information collected. In particular, the informants wanted to know if we had payed any money of which they were not aware to the community leader in order to conduct the fieldwork.

They also discussed with more animosity what they could get in exchange of their participation, and the idea that I could realize a manual on medicinal plants to be used in the community elementary school was very well accepted. First, in the Ashninka language, plants are often given a name based on characteristics like taste, resemblance to a part of the human or animal body, or on their use e.

Anthurium dombeyanum was called maranketza by one informant, from the term maranki which means snake, because the plant was used to cure snake bites. Another informant might have given a different name to the same plant, based for example on its bitter taste: in this case the plant would have been called shawetashi or shawetapini from the word shaweta which means bitter.

This is in accordance with Martin , who reported that indigenous nomenclatures tend to characterise plants on a sensorial and practical base, where taste, smell and use are used and only secondarily on morphology. A second factor to consider is that the majority of the actual inhabitants of the community moved in the area coming from different regions during the.

Some of the slightly different terms which they used to indicate the same species are therefore cognates Martin, The oral transmission of the traditional medicinal knowledge plays also its role. As Bale points out oral transmission tends to make knowledge unstable over the generations. The different application of the medicinal plants can also be related to the various provenance of the informants, which might continue to use the plant for the purpose they learnt when they were young and living in different regions.

Another explanation is that the medicinal knowledge is continuously changing and being updated in response of the need of curing new diseases for example gonorrhoea, mentioned by one young man as being a disease transmitted by promiscuous women in the nearby city.

This is partly in accordace with the findings of Lenaerts b among the Ashninka of Gran Pajonal. This group, closely related to the Ashninka, not only regarded their neighbours, the Matchiguenga, more knowledgeable, but they also thought that their plants were more effective. The difference between the Ashninka and the Ashninka is that, while the firsts believed that remoteness and distance from the western influence was positively related to medicinal plants knowledge, the Ashninka studied by Lenaert highly esteemed their neighbours Matchiguenga and their medicinal plants because they had tighter relations with western world and western medicine.

The correlation between medicinal knowledge in the communities and distance from cities has been studied by Case et al. As it can be seen from the table, all these plants, with the exception of Verbena officinalis, Anthurium dombeyanum, and Syngonium podophyllum are widely mentioned in texts regarding South American medicinal plants. Verbena officinalis is perennial herb native to Europe, and its medicinal application are widely reported elsewhere.

It is interesting that Anthurium dombeyanum Brongn. On the base of the ethnopharmacological approach to drug discovery Martin, , these two species could be suggested for further laboratory analysis. Malaria was introduced into South America from Africa by slave trading during colonial times, while leishmaniasis is an endemic disease in Peru.

As indigenous people have lived with these diseases for centuries, they have individuated local plants which prove efficacious against these diseases or their symptoms. In the community of Bajo Quimiriki the parasitic nature of Leishmaniasis is not understood and the medicinal plants employed have the only purpose of curing the visible wounds which are the symptoms of the parasitic infection. This was also reported by Kvist et al. One of the plants employed by an Ashninka informant, Jacaranda copaia, is a well known species that has been reported elsewhere with the same use Valadeau et al.

Extracts of the leaves of this tree have shown some leishmanicidal properties, but the products were found to be toxic for macrophages Chan-Bacab and Pea-Rodriguez, In the community of Bajo Quimiriki the ashes of the bark of the tree were applied on the wound.

To the best of my knowledge, this preparation has not been reported before and it could be interesting to test wheter this preparation enhances the leishmanicidal activity, while reducing the toxicity previously reported in leaves extracts. All the informants were aware that malaria was transmitted by the bite of infected mosquitoes and in some of the households I saw mosquito nets hanging on the beds.

This is probably due to the fact that this disease and its prevention have been amply publicized by campaigns organized by the Peruvian Ministry of Health, which also distributed free mosquitonets in indigenous communities Harvey et al. In the Loreto region of Peru, Harvey et al.

God to punish them from their sins. In the community of Bajo Quimiriki no informant reported similar beliefs. First of all we share a common interest in preserving indigenous knowledge that had been developed and refined through centuries. Humanity, no matter which place on earth, is built on knowledge gained through generations, and it is in our common interest to continue basing our societies and research on the platforms of knowledge that already exist.

Linden wrote: Some scientists are beginning to recognize that the world is losing an enormous amount of basic research as indigenous peoples lose their culture and traditions. Scientists may someday be struggling to reconstruct this body of wisdom to secure the developed worlds future. Although the concept of losing culture is questionable, because culture is not a fixed entity that can be lost, this statement stresses the importance that indigenous knowledge has also for the developed world.

Ancestral territories in Amazonia are being subtracted to the indigenous people and exploited for commercial purposes like forest logging, cattle production, bio-fuel production, mining and oil extraction. In Peru, the approval by the present government of laws meant to increase foreign investments on oil and gas extraction activities in the territories of the Native Communities has caused violent tensions in the Amazonian region.

During the last two months indigenous people protested through blockades of the main roads and rivers, and at the beginning of this month, June , thousand of indigenous people have protested against this law and several persons died during the clashes between armed forces and indigenous demonstrators. Extractive activities in the forests are very polluting, mostly for the waters, and therefore have a direct impact on the health of the indigenous populations that live in those territories.

Traditional knowledge of indigenous people is threatened by the pressure of the dominant society through the process of acculturation. The cause is not necessarily only the contact with the western world and the increasing inclusion of the indigenous communities in the national market.

What now puts at stake the process of transmission of traditional knowledge from generation to generation is the speed with which socio economic changes are happening. Knowledge today is not only being globalized, distributed and exchanged more intensely than ever seen before in world history, it has also become a good. Medicinal plant knowledge is particularly important because it might help humankind saving many lives. The plant richness of the tropical forests suggests that there might be more useful secondary compounds to be discovered in tropical plants.

Unfortunately, most of the advantages coming from the medical use of tropical plants are shared by developed countries, and not by the communities who first discovered plant properties. In the majority of cases traditional knowledge and genetic material are collected in developing countries, but the benefits from patents and commercialization of medical compounds are received by the companies or institutions that realized the research, being these located in developed countries Martin, However, during the last years, the theme of traditional knowledge intellectual property rights have gained international attention and various solutions are being proposed regarding how to conduct research in the field of drug discovery in an ethical way.

A form of agreement between a pharmaceutical company and indigenous informants which could be used as an ethically-correct example is that of Shaman Pharmaceuticals Inc. In this work I tried to make a first step towards the recognition and description of the traditional knowledge of medicinal plants in the community of Bajo Quimiriki. Considering the pressure from the surrounding society to exploit the natural resources in the area, medicinal plants and traditional knowledge about them is in danger of overexploitation.

During the forest walks, various informants told me how they could see that colonos, mainly from the close-by city of Pichanaki, had entered the territory of the community and removed entire plants considered medicinal, not leaving any roots for regrowth. It could prove to be a good solution for the community to registrer their medicinal plants with INDECOPI, which would ensure the protection of their intellectual property rights, but this does not guarantee protection against overharvesting of the resources by encroachment.

Nevertheless, the strong self-identification and pride of being Ashninka that I noticed among all of my informants does give me some certainty that they will fight for their rights over. Furusawa indicated that modern knowledge is easily integrated into the ethnobotanical knowledge system, but is not directly related to the loss of indigenous botanical knowledge. The proximity to the city of Pichanaki could therefore be seen as something beyond a mere threat for the community, it could in fact be an opportunity, if well managed.

The increasing interest in traditional medicinal knowledge and the demand on the market for medicinal plants, like the worldwide known Ua de gato Uncaria guianensis and Uncaria tomentosa which was reported in the community, could provide the indigenous inhabitants with an additional source of income, provided that the natural resources are rationally managed, avoiding their overexploitation. This could be achieved through small scale cultivation and commercialization of local medicinal plants.

The traditional cultivation of yuca, which required minimum work, is now sided by the plantation of cash crops. The intensified agricultural activities allow less time to be dedicated to traditional activities, like hand weaving of the cushma, the traditional tunic now only worn in special occasions.

Nevertheless, even if the external appearance of the people has changed, the belief in an animated world where spirits of the forest and of the rivers can have direct influence on the health of the people, and the trust in the healing power of the plants are still well established in the community. The Ashninka of Bajo Quimiriki rely on a healing system based almost exclusively on medicinal plants.

During the course of the study almost plants were indicated by the informants as medicinal. Of these, 88 were positively identified and correspond to 62 species belonging to 57 genera and 39 families. The families of Araceae, Solanaceae, Euphorbiaceae, Rubiaceae and Asteraceae provided the majority of the medicinal plants indicated in the community.

The majority of medicinal plants indicated by the informants are herbs, prepared through decoction and administered orally, although shrubs, trees, lianas, epiphytes and arborescent ferns are also used. The plants are mainly collected in the forest and in the homegardens.

The medicinal plants which grow in the homegardens are for the majoriy cultivated, and include a particular category of plants called pinitzi and ibenky Cyperus spp. Other traditional ways of preparation include steam baths, which are usually administered by women.

The uses reported for the same species by different informants were often dissimilar, as well as their indigenous names. This can be a consequence of the different origins of the inhabitants of the community, many of whom migrated in the area during the years of terrorism. Some species were known as medicinal by a high number of informants, although the uses mentioned were often different. Of particular interest are the species Anthurium dombeyanum Brongn.

Further analysis on the species could lead to the discovery of useful secondary compounds. Medicinal plant knowledge in the community is hold both by specialized figures, like the shaman, the tabaquero, the vapour healer, the curandero and the midwife and by everyday users. Within the families, the persons considered most knowledgeable about medicinal plants are the abuelos, the grandfathers, but both men and women of younger age can also have a consistent knowledge of medicinal plants, depending on personal interests and family background.

The treatment of common ailments like mal aire, malaria, diarrhoea, chacho, headache and internal parasites is generally done within the family, while the specialist is consulted if the home remedies do not work or if the illness seems to be related to the malevolent influence of spirits or to witcheries. The shaman practiced the ritual drinking of Ayahuasca Banisteriopsis caapi to be able to diagnose diseases and in order to be connected with the spirits of the forest and re-establish harmony in the eventual imbalances of the community.

His initial aversion to the study can be justified by the high sensitivity level of the medicinal information, which gives him his special status in the community and which provides him a source of income. The revenues from the activities related to herbal and traditional healing, which attracted also many colonos as customers, were probably the cause of tensions between the different specialists.

During the forest walk, where 12 informants were asked about the use of 72 pre-marked plants, women showed a greater knowledge, providing information on the use and preparation of the plants in a major number of events. The knowledge on medicinal plants was significantly correlated to the age of the informants as a whole group, but the correlation was not significant if only the group of women was considered. This supports the theory that although knowledge tends to increase with age, sometimes the variation between informants is better explained by the personal background of the informant.

The children of the elementary school provided names and uses and ways of preparation and administration for 27 medicinal plants. The majority of these plants were growing commonly around the households and were used to cure common ailments in the community. Being the specialized forms of healing shamanism, vapour healing, tobacco healing in the domain of few people in the oldest generation, and considering the fact that there was no young apprentice in the community, the persistence in the future of the traditional healing system can be considered at stake.

The results of the present study, once returned to the community, will provide the inhabitants with scientific information on their medicinal flora, which they can use for the. For example, they will be able to register the uses here described of the identified species in the registers managed by INDECOPI, which will help to protect their traditional knowledge intellectual property rights. Moreover, the manual on local medicinal plants which I agreed to compile for use in the community elementary school, will be a useful material to teach elements of traditional medicinal knowledge in the school, against the process of acculturation.

As the present study reported potential uses of medicinal plants indicated by the informants, a documentation of their actual use, its quantification and the calculation of the relative value of species through quantitative ethnobotanical methods, could be the subjects of following studies.
