Experience of and use of compassion ( Codonopsis javanica (Blume) Hook.F & Thoms) of ethnic Minority Communities in Van Ho District, Son La Province

— This study was conducted with the aim of summarizing and evaluating the experiences of ethnic minority communities in the process of exploiting and using Codonopsis javanica (Blume) Hook.F & Thoms in Van Ho district, Son La province. The research method community interview is applied, the interviewees are those who directly use, exploit, trade and the village heads, healers, mothers, interviewed 80 households in total. The data processing method calculates the percentage based on the answer sheet and notebook. The results show that, 100% of the surveyed households know, can recognize and use C. javanica. This is a fairly popular product locally, but now the quantity is not much. The community clearly describes the growing place, morphology, season, knows how to use the product for health care and trade; 100% harvesting activities are carried out from the wild, breeding activities have not been carried out, only 6.25% of households have tried sowing seeds and only 2.5% of households have tried to plant some C. javanica around the house; 87.5% of mining households are to sell for income; 86.25% of interviewed households want to learn more experience in propagation and planting but only 75% of them are willing to plant if the output market is stable. Experience in commercializing the product is not available, the community only brings the harvested products to the local market or shops to resell. The results from this study show that the local community has a good source of knowledge about C. javanica, but it has not been exploited and applied to conservation and sustainable development of the species. Therefore, this is an issue that needs attention and support, combining both local and technical knowledge, both in terms of the output market so that C. javanica becomes a strength in supporting household economic stability.


INTRODUCTION
Indigenous knowledge is traditional knowledge that is passed on from generation to generation and between communities (Pieroni and Quave, 2005) [6]. For people living near the forest, the knowledge about recognizing, exploiting and using medicinal plants is of great importance. Because, medicinal plants not only have medicinal effects but are also a commodity sold in local markets that significantly increase livelihoods.  [4]; Nguyen Tap (2007) [5]). However, most people only exploit from nature, the main product is tubers, so after harvesting, it often destroys the mother plant layer. C. javanica is recorded in the Vietnam Red Book Uses: Tonic. Cure anemia, jaundice, lymphatic disease, adrenal inflammation; fatigue, poor appetite, cough, stomach pain, lack of milk, loose stools, painful swollen feet (Roots).
Distribution: The tree grows naturally and is also grown in some high mountainous areas.
Van Ho district, Son La province has long recorded the natural distribution and is the place to exchange and trade many medicinal species, including C. javanica. The roots of C. javanica, which are collected in the wild, especially under the forest canopy, are very clean and healthy organic products that are popular with consumers. Together with the sharing from the community about the experience in using C. javanica products for health care, this product has become even more attractive. Population with a specificity, up to 85% are ethnic minorities, mainly H'Mong, Thai, Dao, Muong, Tay, this is a treasure containing a rich source of indigenous knowledge in the use. medicinal plants for daily life, including C. javanica. However, not all indigenous knowledge of the community is relevant to the promotion and sustainable development of C. javanica. Therefore, it is necessary to have summary studies to promote the advantages, recognize the limitations to overcome, and the wishes to build. The article presents part of the research results of the project code B2019-TTB-03, focusing on the experiences in exploitation and use and its potential in conservation and sustainable development practice C. javanica in the community in Van Ho district, Son La province.

Research Materials
Indigenous knowledge of ethnic communities in the exploitation and use of C. javanica in Van Ho district, Son La province.

Research Methods
-Interview survey: Number of interviews 80 votes. Subjects were selected for interviews based on consultation with village heads, commune and district officials. Select experienced people in the village who regularly participate in activities of exploiting, trading and using medicinal herbs and village chiefs, village secretaries, healers, and mothers.
-Interviews were conducted on the basis of simple questionnaires stating a number of key questions to meet the content objectives of the research. The interview process was conducted flexibly, and local languages were used to facilitate collection information.
-Questions to be asked include: Information about interviewees (name, gender, age, education, occupation, ethnicity, address); experience in identifying C. javanica (morphology, flower season, fruit season, autumn); exploitation and use experience; experience in exchange and trade; experience in breeding and planting; other information such as: The village's regulations on the collection of forest specialties, the desire for development and the desire for the market, suggestions and additional open-ended questions on the topic of freedom (if any) . For the management team, they will ask more questions about the status of exploitation, government solutions in protection, planting and development, effectively contributing to the economy. Objectives: To assess the habits and experiences of exploitation, use and consumption, cultivation and propagation (if any) in the community about C. javanica.
-The survey data were processed by mathematical statistical method in forestry on Microsoft Excel software [3]. Summarize all interview opinions on each content then give general comments on experiences in exploitation (recognition, collection, propagation, cultivation) and use (remedy, personal use, etc.) purchase). Calculate percentage by topic.

Experience of the community in mining C. javanica
C. javanica is called by local people with many other names such as Cang ho (H'Mong), Man Ray Cay (Tay), but the name C. javanica is still the most common. Through the interview survey, 100% of the surveyed households confirmed that they knew about C. javanica and at least once had collected, exploited and used. In particular, people all confirmed that many years ago, C. javanica still had a lot, going to the forest to collect firewood, going to the fields to work in the fields, they all met a lot.
100% of the surveyed households confirmed that they could recognize the species in the wild. Of which 77.5% (62/80 votes) said that C. javanica usually grows in natural forests but has been exploited a lot, found in sparse forest canopy, often found on the edge of the forest, sometimes in upland fields, especially in spring (February to April), many trees regenerate in clusters, very rare in old forests where the canopy is thick, dark and moist. The remaining 22.5% (18/80 votes) said that they often   A feature of C. javanica is that when burning the trunk of C. javanica, there is no climbing medium, but it has to spread on the ground, in those nodes, it can grow roots and form small tubers right there. However, when C. javanica grows such secondary roots, it will affect the roots (bulbs) at the main root, leading to nutritional deficiencies and small tuber quality. This is also an experience to note when growing, it is necessary to pay attention to making climbing medium for C. javanica to ensure the best tuber quality.
However, in the past few years, in the season of finding tubers, the amount of tubers earned is much less, mainly because of the small tubers, so the source of income is not much. Very few households experimented with breeding, accounting for 6.25% and only 2.5% of households tried to plant some C. javanica around the house in order to keep some for medicinal use when needed; 86.25% of interviewed households want to learn more experience in propagation and planting but only 75% of them are willing to plant if the output market is stable. The price they are paid is from 30,000 VND/kg to 50,000 VND/kg, depending on the season and year, the price is different. People are willing to participate in forest protection and propagation so that they can meet future needs if they are given technical guidance.
From these data, it is shown that local people have only harvested from natural forests, they are aware of the value, market demand, the reality of the decline of C. javanica, but they are not confident and proactive. to carry out propagation and planting activities. Therefore, this is an issue that needs attention, both technical support and output market so that C. javanica becomes a strength in supporting local economic stability.

Experience of the community in using C. javanica
Results 100% of households interviewed confirmed that they had at least once used C. javanica for themselves or their families. C. javanica is a valuable medicinal herb to replenish the body, but they do not use much because they have to sell it for income. soil. C. javanica dust, depending on the big or small dust, there will be more or less branches, an average of 1-3 branches/dust, sometimes up to 5 branches/dust for perennial bushes. Each year, there is a main harvesting season, which is around December to February next year, when the tree has already produced all the fruit, the tree will dry out and die on the ground, leaving only the tubers in the soil. best for mining. After exploiting, if you sell it, you only need to do preliminary work and then sell it.

If the roots are left to the family to use as medicine, they should be washed and then dried or used fresh depending on the remedy. Some simple tonic remedies with Dang ginseng such as: Cooking soup, stewing with chicken, soaking in wine (this is popular and often chosen by people). The steeping of Dang ginseng is also available for commercial purposes because it will not lose Dang ginseng and preserve the product for a long time if it is not sold immediately after harvesting. In addition, Dang ginseng is also combined with a number of herbs to create common remedies such as: Indigestion, fatigue, vomiting or diarrhea, etc. However, the formula combines all kinds of drugs that kept private because these are family secrets.

IV. CONCLUSION
-C. javanica is a familiar product to the ethnic minority community in Van Ho district. The community here clearly describes the morphological characteristics, growing season, growing conditions. The community wishes to receive technical support to plant and develop species if the output is guaranteed to be stable.
-The community knows well the experience of exploiting tubers to obtain quality tubers, the exploitation of small tubers and extermination is still quite common because of economic needs. The community has good experience in using and trading. Trading activities are still very rudimentary, there are no breeding and planting activities to actively source products.
