Observations on traditional usage of ethnomedicinal plants in humans and animals of Kangra and Chamba districts of Himachal Pradesh in North-Western Himalaya, India.

ETHNOBOTANICAL RELEVANCE

Medicinal plants are frequently used by Gaddi and Gujjar tribes of Kangra and Chamba districts of Himachal Pradesh, India to cure various ailments in humans and livestock. Therefore, extensive field work was conducted to document the traditional use of ethnomedicinal plants by these tribes.

MATERIALS AND METHODS

Direct interviews of 208 informants were conducted. The data generated through interviews was analysed using quantitative tools such as use-value (UV), factor informant consensus (Fic) and fidelity level (Fl).

RESULTS

A total of 73 plant species in 67 genera and 40 families were observed to be medicinal and used to cure 22 ailment categories. The highest number of ethnomedicinal plants was recorded from the family Asteraceae followed by Lamiaceae, Apiaceae, Acanthaceae, Caesalpiniaceae, Polygonaceae, Ranunculaceae, Rosaceae and Rutaceae. Leaves were the most frequently used plant part used to treat various ailments followed by whole plant and roots or rhizomes. Ajuga parviflora, Berberis lycium, Viola canescens, Vitex negundo and Zanthoxylum armatum were the most important medicinal plants used for treating human diseases, whereas Achyranthes bidentata, Aloe sp., Cassia fistula, Podophyllum hexandrum and Pogostemon benghalensis were the most important medicinal plants used for treating animal diseases as per use value. The important ailment categories classified on the basis of factor informant consensus were gastrointestinal and respiratory disorders.

CONCLUSION

The present study revealed that people of the study area are extensively using the ethnomedicinal plants to cure various ailments. Plants with high use value and fidelity level should be subjected to pharmacological investigation for scientific validation.
