• Different herbal extracts and brief discussion on various extraction processes

Extracts

Extracts are concentrated herbs in liquid form. Powdered or dried herbs are added to a fluid or solvent and then stored for a suitable period of time. Alcohol-based extracts are usually preferred over other solvents. Herbal extracts can be classified as follows:

1. Fluid extracts: These are more concentrated hydroalcoholic preparations.
2. Solid extracts: These are concentrated preparations obtained by evaporating the solvent used for extraction and are available in powder form
