Abstract
The study carried out to assess the consumption of raw drugs by the drug industry in northern Kerala revealed that the annual consumption of 140 major raw drugs is 11,350 tonnes of which 83 per cent is consumed by large units, 6 per cent by medium units and 11 per cent by small units. Among the 140 raw drugs, 117 occur in Kerala. Forty-five per cent of the raw drugs are collected from the forests, 14 per cent from non-forest areas, 14 per cent from cultivation and 8 per cent through imports. Another 20 per cent occurs in the forests as well as non-forest areas. The study also revealed that occasionally unrelated species are substituted for some of the preferred species of the raw drugs.
