Trang 9I Introduction
Forest is a precious resource, is an important part of living-enviroment which is closely related to ethnic minority’s life Forest not only plays vital role in business but also is very meaningful for science, gene conservation, biodiversity conservation, climate regulation, watershed protection, disaster mitigation, preventing desertification, erosion control, flood defence, ensurement national security and defence, also create stunning landscape for biotourism, community tourism
Long time ago, a number of people have cared about the medicinal plants which is resource plant is essential for the local community in desease prevention Besides, it is also valuable for gene protection, provide for medicinal science
Hitherto, Viet Nam is evaluated which one of countries that has a diverse resourse of creature, medicinal resourse of plant is one of that, specially in Truong Son area Additionally, with experiences are saved through 4000 year’s history, made use of resourse for demands of life such as: food, clothe, living, heathcare, and treatment, etc in 54 ethinic-communities It is big advantages in making use of resource of plants meanwhile resource of medicinal plants contributes to enhance the quality of life and health for everyone specially for ethnic minority who live in the remote, get a great deal of difficulties and their lives depend on natural resources
a lot and forest is one of them
According to plant taxonomist, Viet Nam is the richest country of resource plants in ASEAN where has around 12,000 high degree plants There are 3,948 species that are used to make medicine (Medicinal plants institude,2004) accounting 37% all of the researched species This number is not including traditional medicines that exist in 54 ethnic communities Until now, we have just known a part of it In addition, agricultural scientists have identified 1,066 species of plants, including 179 species used in medicine According to a survey conducted by the Institute of Medicinal Materials in the period of 2002 - 2005, the number of medicinal plants
Trang 10species), Gia Lai (783 species), Kon Tum (814 species), Lâm Đồng (756 species) With such a flora, the composition of medicinal plants is very rich and varied
Health is one of the most crucial part of human-being, we are not always healthy and some cases we get sick, get desease in which we need medicine to treat it and improve our daily life Specially for ethnic minority in the remote area in which the medicine is not always available Medicinal is an available resource living around people which is safe and powerful
to treat That why traditional medicine is very necessary and extremely important Sometimes
it is called “invisible power” to save human-being
Through centuries, medicinal plants play an important role in maintaining health and happiness in human community all over the world Traditional experience about how to use medicinal plants is researched in many different levels what relies on how developed country
is Therefrom, each continent, each nation has built up a characteristic medicinal plants:
- Medicinal plants in Europe is very diverse and most of them are based upon the traditional medicine A doctor in Greek named Dioscorides wrote a book “De material Medica” made a statistic about 600 medicinal plants; Nicholas Culpeper published “The English Physitian” …
- China and India have a long-term traditional medicine In China, Li Shizhen (16th
century) counted over 12,000 medicinal plants in “Compendium of Materia Medica” In 1977
in the book “Encyclopedia of traditional Chinese remedies” counted that 5.757 words, the majority is medicinal plants In the book “Medicine plant” published in 1986 enumberated all
of the medicinal plants in China ever since In India, traditional medicine, Ayurveda developed very well, native knowledge was researched, evaluated and applied powerfully According to the statistic, there are 2,000 plants used for making medicine
- In Viet Nam, a number of researches on medicinal plants was conducted very early, associated with the names of famous doctors such as: Tue Tinh or Nguyen Ba Tinh (14th
Century) with “Nam duoc than hieu” including 11 books, 496 medicinal herbs, inside that there
Trang 11are 241 medicines which originate from plants Hai Thuong Lan Ong- Le Huu Trac 1792) with “Linh Nam Ban Thao” collected 2854 medicinal herbs to treat by traditional experience Colonial France period, Western Reseacher such as: Crévost, Pétélot pulished
(1721-“Catalogue des produits de L’lndochine” (1928 - 1935) and “Les plantes de médicinales du Cambodge, du Laos et du Vietnam” including 4 books made statistic 1482 medicinal herbs in
3 countries in Indo-Chinese After the North was liberated in 1954, Vietnamese scientists have many advantages in collecting, studying medicinal plants resources with many typical works such as:
- Vu Van Chuyen, 1966, Summary of medicinal plant families
- Do Tat Loi, 1986, Medicinal plants in Vietnam
- Pham Hoang Ho, 1991-1993, Plants in Vietnam
- Võ Văn Chi, 1996, Dictionary of medicinal plants in Vietnam
- Tran Dinh Ly, 1997, 1900 useful plants in Vietnam
- Nguyen Nghia Thin, 2001, Medicinal plants of Thai people in Con Cuong, Nghe An
- Institute of Medicinal Materials, 2003, Medicinal plants and annimals in Vietnam
- Ministry of Science and Technology, 2007, Vietnam Red Book
At present, our forest resources are severely degraded, the decline in biodiversity, including valuable indigenous medicinal plants, has also diminished Researching, discovering and conserving on the sustainable use of indigenous medicinal plant resources is a very necessary issue in the current period For ethnic communities in Tan Pheo commune - Da Bac district - Hoa Binh province Among them are the H'Mong community who have medicine, very good experience, simply effective in healing The issue is how to recognize and preserve precious knowledge in the use of medicinal plants, remedies of the H'Mong ethnic community

Diversity of medicinal plant in the study area
Diverse at the division level
During the survey, data collection from flora species, I have collected 131 species, 129 genus and 69 familia belonging to four valuable divisions Data are shown in Table 5.1
Table 5.1 Composition of taxon medicinal plants in study area
- Lycopodiophyta division has 1 family (1.45%), 1 genus (0.83%), 1 specie (0.76%)
- Pinophyta division has 2 families (2.90%), 2 genus (1.67%) and 2 species (1.53%)
- Polypodiophyta division has 3 families (4.35%), 4 Genus (3.33%), 4 species (3.05%)
- Magnoliophyta division with highest number of families, genus and species: 63 families (91.30%), 113 genus (94.17%) and 124 species (94.66%)
The results of the analysis of the taxon of Magnoliophyta division are shown in Table 5.2
Trang 22Table 5.2 Number of family, genus and species of Magnoliophyta division
in the study area
Trang 23Diversity at family level
I have listed top 10 most diverse medicinal plants in the study area in Table 5.3
Table 5.3 Top 10 most diverse medicinal plants in the study area
Trang 24The results show that 10 families with the largest number of species in the study area include: Asteraceae, Lamiaceae, Araceae, Euphorbiaceae, Poaceae, Zingiberaceae, Moraceae, Fabaceae, Caesalpiniaceae and Verbenaceae The total number of species of these 10 families
is 51 species, accounting for 38.93% of the total number of species found in the study area, and
48 out of 120 genus accounts for 40.83% These are families with many species in Vietnam, focused on shrubs, easy to exploit, easy to recover
5.1 Diversity of life forms of medicinal plants
According to the system of division of plant life forms “Name of forest trees in Vietnam 2000”, There are 8 major life forms in the study area The results of the study are presented in Table 5.4
Table 5.4 Distribution of life forms
As shown in Table 5.4, the herbaceous used for medicinal plants has the largest number
of species, with 55 species accounting for 41.99%, 28 species of woody species accounting for 21.37%, followed by shrubs accounting for 16.79% and at least Palmae occupies 1.53%
It can be seen that the woody is ranked second in the life forms used as medicine Therefore, the unreasonable harvesting the parts of the medicinal plants not only affects the growth and development of timber in particular, but also affects the structure of the main forest floor in general
On the other hand, the medicinal plants used by the healers are taken from the forest,
Trang 25the plants grown in the home garden are not many and are often used to treat common diseases With the concept of local people, they think that the medicinal plants are taken from the forest better for healing and the cultivation of medicinal plants at home is not simple, especially the rare medicinal species Moreover, the purpose of growing medicinal plants in the garden of local people is simply to reduce the distance to collect the medicine in the forest, but not consciously aware of the issue of conservation The essential issue here is the need for education policies for people to be aware of the benefits from the forest so that they can use it properly and protect the local medicinal resources
Studying the life forms of plants as medicinal plants has important implications, the results not only show what life forms are used, but also the direction for finding, use as well as find measures to cultivate, protect high efficiency
Diversity of the parts of medicinal plants
Studying the used parts of plants helps to make efficient use of material and to orientate the analyses of the chemical composition as well as its pharmacological properties In order to know the diversity of using different parts of plants for medicine, the preliminary results are shown in Table 5.5
Table 5.5 The ratio of the parts of plants used as medicine
Trang 26The data in Table 5.5 show the abundance and diversity in the use of plant parts for medicinal purposes The number of species with all parts used for medicine is the highest
proportion: 28 species (21.37% of total species), including representatives: Balanophora fungosa (Dương đài nấm) for abdominal pain therapy…, Sarcandra glabra (Sói nhẵn) for cure epilepsy, Taxillus gracilifolius crelieve knee pain, rheumatism, boils , Solanum surallense (Cà
