Herbal decoction being prepared in a traditional pot.

A decoction is a method of extraction by boiling herbal or plant material to dissolve the chemicals of the material. It is used to extract fluids from hard plant materials such as roots, bark, and seeds. Decoction involves mashing and boiling the plant material to extract the active ingredients, which are then consumed as a liquid.

Preparation

The process of making a decoction involves several steps:

1. Selection of Material: Choose the appropriate plant material, typically roots, bark, or seeds, which are known to contain the desired active compounds.
2. Mashing: The plant material is often crushed or cut into smaller pieces to increase the surface area for extraction.
3. Boiling: The material is placed in water and brought to a boil. The boiling time can vary depending on the material and the desired strength of the decoction, but it typically ranges from 20 to 45 minutes.
4. Straining: After boiling, the liquid is strained to remove the solid plant material, leaving behind the decoction.

Uses

Decoctions are commonly used in traditional medicine systems such as Traditional Chinese Medicine (TCM) and Ayurveda. They are believed to extract more potent active ingredients compared to other methods like infusion.
