ABSTRACT
Salem
district sustain a very rich traditional medicinal plant wealth and inherits
unique plant and animal communities. Due to deforestation, loss of
biodiversity and indiscriminate exploitation of wild and natural resources
many valuable herbs like Abrus precatorius, Gloriosa superba, Martynia annua etc are in the
verge of extinction. The present paper enumerates status, conservation
strategies and traditional uses of 68 plant species by the ethnic and rural
people of Salem
district of Tamilnadu. The claims were gathered by
interviewing traditional healers, especially villagers of the study area.
Attempt was made to verify the efficacy of claims with actual beneficiaries,
though it was not possible in all cases due to social customs.
INTRODUCTION
In ethnobotanical
studies, the major contribution has been in the field of medicine. A large
number of ethnomedicinal information remained
endemic to certain regions or people due to lack of communication. India is
the second largest country in the world in respect of human population. Over
550 tribal communities are covered under 227 ethnic groups residing in about
5000 villages of India in
different forests and vegetation types (Sikarwar
2002). The ethnic and rural people of
India have preserved a large bulk of traditional
knowledge of medicinal uses of plants growing around them. This knowledge is
handed down to generations through word of mouth and is extensively used for
the treatment of common diseases and conditions. Herbs are mines of useful
drugs. it is evident that many valuable herbal drugs
have been discovered by knowing that particular plant was used by the ancient
folk healers for the treatment of some kind of ailment (Ekka
& Dixit 2007). Moreover, the medicinal plant
wealth is our national heritage and it seems to be the first and foremost
line of defense for the treatment of various diseases mostly in tribal and
rural communities. During the field survey it has been found by the authors
that there are number of plants which are used by the ethnic and rural people
of the region in curing various ailments and till date no any proper work has
been performed by the research scholars of the area with proper citation and
hence the present work was conceived by us to explore the hidden uses of the
species. Salem is
an important district of Tamil Nadu noTable for its picturesque landscapes dotted with
hillocks, lakes, temples and forts etc. The district has its administrative
head quarter located at the same town of Salem.
Other major towns of the district include Mettur, Omalur and Attur. Salem was
the largest district of Tamil Nadu before it was
bifurcated into two administrative districts viz. Salem and Dharmapuri districts. Again it was divided to form Namakkal District. Some important facts and figures about
Salem
district has been mentioned in Table 1.

OBJECTIVE OF THE WORK
1.
To collect
scattered scientific information and identify the herbs used by the ethnic
and rural people of Salem district of Tamilnadu.
2. To
provide status of the plants which are endangered, vanishing or in the verge
of extinction.
RESEARCH
DESIGN AND
METHODOLOGY
Following methods were adopted by the authors
during the course of present investigation:
1.
The plants used
by the ethnic and rural people in the treatment of various diseases were
collected by the investigator from the different study sites of Salem district during Aug-2007 to Jan 2008.
2. Field
and survey work was made after carefully planned field trips. During the
field trip personal interview was made between the authors and tribes of the
regions.
3. Data regarding herbal remedies were
collected as per plan suggested by Dwivedi (2003), Sinha (1998), Varghese (1996).
4. Voucher specimen were collected from
different study sites and preserved as per method suggested by Agrawal (1983).
5. The plants were identified by Dr. M.U.Shariff, scientist, Botanical survey of india, Yercaud, Tamilnadu.
6. Confirmation of the
specimen were made with
the help of floristic literature Kurian (2003), and
Khare (2004).
STUDY
AREA
The present investigation has been carried out in
the Salem district scattered over 5 villages and towns( Yercaud, Belur, Koneripatty, Pinanur, Pachmalai ). For a
proper and orderly study, the study sites were selected considering the
population and density of flora. The local informants selected are:
1.
Village farmers
2. Old
persons
3. Hakims, vaidhayas,
gunias and ojhas
4. People working on field
5. Ayurvedic doctors
6. Experts in the field of herbal medicine
OBSERVATIONS
STATUS, CONSERVATION
STRATEGIES AND
TRADITIONAL USES
During the course of the present work, the authors
tried to have some idea of endangered, vulnerable, threatened, and rare
medicinal plants. The status of medicinal plant of the study area has been
established (Mc.Neel et al 1990, Phillips et al
1994), and the conservation strategies of these plants have been mentioned in
Table 3. Direct discussion between the authors and different informants were
made and the uses of the plants were recorded, mentioned in Table 2.
DISCUSSION
AND
CONCLUSION
In every ethnic group there exists a traditional
health care system, which is culturally patterned. In rural communities
health care seems to be the first and foremost line of defense. The WHO has
already recognized the contribution of traditional health care in tribal communities.
In the present work authors have collected 68 plant species from different
study sites. These species contain valuable chemical substances and are
useful to cure various human ailments (Table-2). During the course of present
investigation it has been found that 4 species are endangered, 3 vulnerable
and rest are rare. It is very essential to have a proper documentation of
medicinal plants and to know their potential for the improvement of the
health and hygiene through an eco friendly system. Thus importance should be
given to the potentiality of ethnomedicinal studies
as these can provide a very effective strategy for the discovery of useful
medicinally active identity. A detailed and systemic study is required for
identification, cataloguing and documentation of plants, which may provide a
meaningful way for the promotion of traditional knowledge of herbal medicinal
plants. The present study reveals that the Salem district is rich in herbal medicine with
diversified ethnobotanical values. From the Table
presented, it can be seen that there is a wide variety of plants for common
ailments and diseases. However different types of strategies are required to
adopt to conserve the plants, which are vulnerable and endangered.
ACKNOWLEDGEMENT
The authors are thankful to the rural villagers
and crude drug sellers of Salem
district for the valuable information required for this survey. Heartily
thanks to Dr. M. U. Shariff, Scientist, Botanical
survey of India, Yercaud for their
valuable guidance and support for the identification of medicinal plants.
