Large numbers of taxa of medicinal properties including highly traded species are found in the districts. The medicinal efficacy of dry zone wild species is considered as very high. The use of herbal combinations for immunity boosting will reduce the pressure from medical infrastructure and increase quality of life. The forests of Bidar district are found having better wild herbal biodiversity, site quality and may be considered immune boosting centre. Ocimum sanctum, considered as one of the best immune boosters of high efficacy is widely found in all the forests of three divisions. The Ayush department of the State may take note of it. Based on the assessment certain areas have been recommended for gene pool conservation for medicinal plants. The percentages of herbs of medicinal value in the floral population are found high in these districts. The study has also laid stress on estimation of herbal medicinal resources for better management.
