The herbs and their parts are collected at a time when they are rich in their active constituents.All the drug substances are painstakingly analyzed through multidisciplinary approach using high-grade technology implementation.

The part used in preparation of the Mother Tincture is strictly matched with the H.P.I.  Suppose when the part used is “root", not a single piece of stem, leaf or flower of the same plant is allowed in the sample. Macroscopical study of the drug substance ensures superior quality of the raw material, which is free from any contamination.

Microscopical study of the drug substance is done to ensure the confirmatory properties of the drug substance and its part used is present in the sample.

Testing the purity by means of UV- Spectrophotometer to confirm the quality of the raw materials as per H.P.I.standards.
