Abstract
Drying is one of the most critical and fundamental unit operations in the post-harvest processing of medicinal plants.
The quality of drug and consequently the earnings are significantly influenced by the drying regime.
Energy demand of drying can also be a very significant factor because of high initial moisture content of the flowers, leaves and roots.
To prepare high-quality products, considerable attention should be devoted to the drying process.
This review primarily focuses on the methods available for drying of medicinal plants and the effects of drying factors on the quality of the final product.
Several empirical models for the drying of medicinal plants have also been discussed.
