There are 4 collection centres where the raw materials  for different medicines are collected . The collection of these materials is a job requiring compact knowledge, care and attention. Different parts of a plant are used for different   purposes at different times.  A plant can be used in various diseases by its various parts, sizes, conditions, and stages. These raw materials are classically picked, carefully collected, deftly dried and cautiously cleaned.

In the year 1997-98, these centres were provided with modern machinery like Micropulverizers and Hammer crushers.  Collected raw materials are converted into Choorna ( powder form ) at  the centres only. Thus, clean Choornas are directely sold  to the Ayurved hospitals and dispensaries in the state.
