How Ghanvati is Made?

Ghanvati (Ghan Vati) is an Ayurvedic tablet preparation made using concentrated herbal extracts. The term "Ghan" means solid extract, and "Vati" means tablet.

Step-by-Step Process of Making Ghanvati:

1. Herb Selection & Cleaning:

   • The required herbs are selected based on their medicinal properties.

   • They are cleaned thoroughly to remove impurities.

2. Decoction (Kwath) Preparation:

   • The dried herbs are boiled in water to extract their active compounds.

   • The process continues until a concentrated liquid extract is obtained.

3. Filtration & Concentration:

   • The decoction is filtered to remove plant residues.

   • The liquid is further heated to evaporate excess moisture, forming a thick paste or solid extract (Ghan).

4. Tablet Formation:

   • The thick herbal extract is dried into a powder form.

   • A binding agent like Gum Acacia (Babool Gond) or natural starch may be added for proper tablet formation.

   • The extract is compressed into tablets using a tablet press machine.

Why is Ghanvati Black in Color?

• The black or dark brown outer layer of Ghanvati is not a coating.

• It naturally forms due to the high concentration of herbal extract.

• The color comes from tannins, alkaloids, and other phytochemicals present in the herbs.

• Some manufacturers may add natural excipients (like starch or gum) to improve tablet integrity, but no artificial coating is applied.
