How to make a decoction
What is a decoction?
The art of decocting herbs is at the heart of the herbal tradition. A decoction is made by boiling a set weight of herbs in a specific volume of water and reducing it to the required strength. See it as a herbal tea that has been simmered to extract the properties of the herbs.
What is the difference between a decoction and an infusion?
Decoctions are used over infusions when you want to extract the constituents of hard or woody parts of plants such as barks, seeds and roots. Decoctions tend to be stronger and more concentrated than infusions. They may also be used for more focused cleansing or tonifying. They are especially valuable for herbs like licorice or astragalus that contain little or no essential oils. Delicate flowers and leaves are often added at the end of a decoction to preserve their more volatile properties.
What is a decoction used for?
Decoctions are often used as a strong herbal tea, as a base in syrups and for fomentations applied externally.

Helpful Hints
- It is important to start your decoction with cold water rather than placing the herbs directly in boiling water.
- The ratio used in the Ayurvedic tradition is 1 part of dry herb : 16 parts water, which is then reduced to 4 parts of the original volume of water. For a quicker method use 8 parts water and follow the same steps.
- Chinese and western herbal medicine also uses decoctions for powerful benefits. Roots, barks, stems and fruits are usually decocted with the more delicate leaves and flowers added at the end of the decoction to infuse with the other herbs for a few minutes.
