Darjeeling Himalayan region is characterized by a rich floral diversity. Since most of the hilly terrain is devoid of modern medical facilities, the people here are dependent on Traditional Medicine Systems for their health-care. During the course of the study, it was found that 37 species of plants belonging to 29 families are utilized as antipyretic agents in the different ethnic medicine practices prevalent in the region.

Body temperature rises due to derangement of heat regulating mechanism in the brain. The rise in body temperature above 99F is called fever. Fever generally occurs due to the infections by virus, bacteria, protozoa and other microorganisms that produce pyrogens. These pyrogens act on WBC which in turn produce endogenous toxins. They act on the anterior hypothalamus and the body temperature is elevated causing fever1. Fever leads to the disturbance of metabolism and it increases blood pressure, pulse rate, cardiac output, respiration rate, etc. Most Traditional Medicine Systems believe that fever is not a disease in itself but the symptom of some other diseases. The antipyretic agents treat these symptoms and completely eliminate fever. Herbal antipyretic agents are favoured over the chemical ones for their compatibility to the human physiological system, easy availability and the rich knowledge about the traditional healing systems.

Darjeeling hills are situated between the 280 31'-270 13' North and 870 59' -880 53' East in the Eastern Himalayan region of India. Out of the four sub-divisions of Darjeeling district, Kalimpong, Kurseong and Darjeeling Sadar comprise the hilly areas covering an area of 2417 sq km. These hilly regions are further divided in 8 blocks. The population of the hill areas of Darjeeling is above 1 million of which 78.42% population lives in rural areas and 21.5% in urban agglomerations. This part of the Himalayas is the cornucopia of ethnicity. The major ethnic groups of the region are Lepcha, Bhutia and the Nepalese. Nepalese is a conglomerate of mongoloid tribals like Sherpa, Limbu, Tamang, Yolmo, Kagatay, etc. and the aryan non-tribals like Chhetri, Bahun, Sanyasi, Kami, Damai, etc. Intermediate between the two groups are the Newars, showing partial characteristics of both the groups. Each of these tribal groups has its own distinct culture, language and traditions. However, Nepali language is the medium of communication between the tribes. These tribes also have rich ethnomedicinal traditions for which a few records are available2-7. The prevalence of the folk-medicine practice is found in places where the amenities of modern society are not available. The tough terrain and vast natural barriers force the people of this region to depend on herbal medicine8. However, the use of Traditional Medicine is prevalent even among the urban people of this region9.

 

Methodology

Regular field trips to different areas of Darjeeling hills were conducted between September 2001 and April 2003 to collect the ethnomedicinal information and herbarium specimens. Altogether, 19 villages were covered during the ethnomedicinal field survey of the present study. These villages are Maney Bhanjyang, Sukia Pokhri, Kal Pokhri, Meghma, Chha Mile, Permaguri, Majhidhura, Lami and Rimbik in Darjeeling Sadar sub-division; Sukna, Garidhura, Namsu, Turyok, Lanku and Rollok in Kurseong sub-division and Gorubathan, Gairibas, Tohday and Pedong in Kalimpong sub-division. The tribal people including local healers, Jhankris (Nepalese traditional healer), Bongthings (Lepcha medicine men), Lamas (Bhutia priest) were interviewed. A total of 28 traditional healers were interviewed during the course of the study. Information from elder persons from the villages having some idea of the local herbal traditions was also gathered. Preliminary identification of collected plant materials was done with help of the Traditional Medicine practitioners. The local names of the plants and information regarding their use were also recorded with the help of these practitioners and village elders. Information obtained from more than three sources only has been incorporated here. Subsequently, the collected plants were identified at the Panchavati Greentech Research Society, Darjeeling and the voucher herbarium specimens were deposited in the herbarium of the Medicinal Plants Division, Panchavati Greentech Research Society, Darjeeling, India.

Discussion

In the present study, it was found that a total of 37 species of plants belonging to 29 families are utilized in the Darjeeling Himalayan region as a medicine for fever. The family with highest number of plants showing antipyretic activity is Rubiaceae (4 species) followed by Apiaceae, Menispermaceae, Ranunculaceae and Rutaceae (2 species each). Rest of the families is represented by only one species each. The medicinal recipe was generally prepared in the form of infusion or decoction (by boiling or soaking in hot water); extract or juice (by crushing the fresh plant parts with or without water); powder (by grinding the dried plant parts).

Considering the plant parts used, over 60% of the plant collections involve destructive harvesting practices because of the use of plant parts like root (30%), rhizome (8%), bark (13%), stem (2.7%) and whole plant (11%). This pattern of use poses a definite threat to the genetic stocks and to the diversity of medicinal plants10. Therefore, the herbal heritage of this Himalayan region must be protected for the posterity, which may ultimately lead to the development of new molecules for human health as well as national economy.
