Chhindwara district lies between latitude 21 Deg 23' and 22 Deg 49' north and longitude 78 Deg 10' and 79 Deg 24' east. Mostly, the dense forest covers most of the area of the district.
Patalkot is a lovely landscape located at a depth of 1200-1500 feet in a valley near Tamia in the north of the district. Because of the great depth at which it is located, this place is christened as 'Patalkot' (Patal means very deep, in Sanskrit). Patalkot is spread over an area of 79 Sq.Km. at an average height of 2750-3250 feet above Mean Sea Level. It is a treasure of forest and herbal wealth.
There are 12 villages and 13 hamlets in this valley, with a total population of nearly 2000. Because of the inaccessibility of this area, the tribals of this region were totally cut off from the civilized world. Most of the people in Patalkot belong to 'Bharia' and 'Gond' tribes. This valley is situated on the Satpura plateau in the southern central part of the Madhya Pradesh.
During the survey which carried out from 1997 to 2004, Dr Acharya explored the area of Patalkot valley that included- Gaildubbha, Karayam Rathed, Ghatlinga, Gudichhathri, Karrapani, Tamia Bharia Dhana, Bijauri, Pandu Piparia, Sajkui, Lahgadua, karrapani, Sidhouli.

Why we select this plant?
Plants have been source of medicine for the ancient time. Thousands of books and articles have been written so far. Several thousands medicinal plants are discussed and used to cure various health disorders in India and abroad also. In India, almost 45000 plant species are growing naturally or being cultivated. There are so many popular Indian herbs used in traditional practices to cure diabetes. Gymnema sylvestre is having an important place in such antidiabetic medicinal herbs. It has shown experimental or clinical anti-diabetic activity (ENVISBSI, 2004) and it boosts your insulin level (Gent et al., 1999).
During the early 1990's, this marvelous herb was found in abundance in Patalkot valley. It's a climber and it could not survive well after the deforestation and cutting down of the big trees.
Nowadays, this herb is becoming rare in this valley. It evokes us to write an article and make it an issue so that, conservationist, botanist and NGO's come forward to rescue and save this plant in the valley.

It is the need of the hour to save this highly important medicinal plant of Patalkot valley. If proper initiatives would not be taken in time, there would not be single Gymnema plant in the valley. It is urged to the scientists, conservationists, researchers, NGO's and other bodies to come forward and take moves to protect this important herb. Local farmers should be encouraged to cultivate this herb. Government and policy makers are having lots of plans/ ideas but they find problems in proper implementations. It is the youth and people from literate world who should come forward to take this task in their hands.
