Decoction

A decoction is a method of extracting the flavors, medicinal properties, or other qualities of a substance, typically plant matter, by boiling it in water. This process involves prolonged simmering, often at a lower temperature than a rapid boil, to allow for a gradual and thorough infusion of soluble compounds into the liquid. The resulting liquid, the decoction itself, can then be consumed for its purported benefits, or used in other applications. Unlike infusion, which uses hot water, decoction is often used for harder materials such as roots, barks, and seeds, while infusion may be used for softer materials such as leaves or flowers. The duration and temperature of the boiling process vary depending on the substance and the desired outcome. The precise time and heat control are considered key to the preparation of a decoction. Different herbal decoctions have different medicinal properties and their preparation is important to maintain.

Decoction meaning with examples

• In traditional Chinese medicine, a specific blend of herbs underwent a careful decoction process. The herbalist meticulously measured the ingredients, placed them in a ceramic pot, and simmered them at a low temperature for several hours, carefully monitoring the process.
