The miracle-makers
Scientists are only now finding out the Kanis' knowledge of herbal remedies.The most outstanding find so far is arogyapacha.
SMELL of burning bamboo. The short and wiry figure of Ayyappan Kani. The elderly man is busy mixing herbs with a strange extraction from a piece of burnt bamboo. With a beatific smile, he explains that it will treat a boil on a little girl's belly. The place is Chonanpara, a Kani tribal settlement in a reserved forest of Kerala's Thiruvananthapuram district. Ayyappan Kani is a practitioner of malamarunnu, the medicine of the mountain, given to the Kani tribe by the mythical sage Agastya.
About 40 km away in Njaranili village, townsfolk come to consult Eswaran Kani, a traditional tribal healer. The pious medic explains that people gave him the nickname 'Eswaran' (meaning god) after he successfully treated some patients sent back by the Medical College Hospital, Thiruvananthapuram.
The Kanis, numbering about 16,000, live in the lush tropical forests of the Western Ghats. According to Kani myths, their ancestors were exceptionally adept at shooting arrows. The ancient sage Agastya disarmed a Kani couple to prevent the birth of a martial race in his abode of peace and meditation. Instead, the couple were given a scroll on herbal remedies. And a boon to cure the sick with their chants. Kanis are now known for their sure-fire antidotes. The tribal knowledge of forest plants holds the key to several new discoveries and wonder drugs, a multi-billion-dollar business worldwide.
The Kani tribe's contribution from that treasure trove is arogyapacha (Trichopus zeylanicus), a herb with tonic qualities. In Malayalam arogyapacha means 'health green'. Indeed. Its business potential is comparable to ginseng of Korea, says P Pushpangadan, director, Tropical Botanical Garden and Research Institute (TBGRI), Thiruvananthapuram. Trained in Ayurveda and botanical research, Pushpangadan is a pushy seller of ideas. "In South Korea, a large share of the foreign exchange is earned from ginseng," he notes. With its anti-fatigue properties, arogyapacha is a potential global hit, he says. Arogyapacha is the quintessential wonder herb. It possibly has immune-enhancing and liver-protecting qualities, claim scientists of TBGRI.
Pushpangadan says he first came across the wonder herb in 1987, before the birth of TBGRI. During an arduous trek through the forests near the Agastya hills in Thiruvananthapuram, Pushpangadan and his colleague S Rajasekharan got a sudden "flush of energy and strength" after eating the seeds of arogyapacha given to them by two Kani guides.
After isolating the herb's rejuvenating properties, TBGRI scientists developed a traditional drug formula containing 15 per cent arogyapacha. They scientifically tested its toxicity and efficacy. "It took eight years of research," says S Rajasekharan, now an ethnobotanist at TBGRI (ethnobotany is the study of traditional knowledge and custom of a people relating to plants). "Starving rats ran around after consuming arogyapacha," narrates Ayyappan Kani about the tests.
In November 1995, TBGRI sold the formula to Arya Vaidya Pharmacy (AVP) of Coimbatore for a licence fee of Rs 10 lakh to produce the drug for seven years. The licence fee and the 2 per cent royalty on the profits from the formulation was to be shared equally by TBGRI and the Kani tribe.
In 1995, the government's Integrated Tribal Development Project in Nedumangad initiated a scheme in collaboration with TBGRI to help the Kanis grow medicinal plants in their settlements. Under the project, 50 select families received Rs 1,000 each. Reportedly, 20.25 hectares were under cultivation. "Many people successfully cultivated arogyapacha" notes Rajasekharan. TBGRI bought the leaves from the Kanis, paying Rs 30 per kg for chemical trial and for pilot production.
"We are now documenting the tribal medical knowledge and details of the medicinal plants that the tribals use," says Vishwanathan Nair, director, KIRTADS. A PhD in tribal medicine, Nair says he refused to publish his thesis as he first wanted to know what the tribals have got. He also fears that any private firm might grab the tribal knowledge to make profits once the information is out as a book. There is no law to share benefits with tribals, he indicates. Nair's fear means that tribal knowledge will remain canned till a 'brave new world' dawns and the system sheds the red tape. High hopes.
