A decoction is a method of extracting flavors and nutrients from hard plant materials, such as roots, bark, or seeds, by boiling them in water. This process typically involves simmering the ingredients for an extended period, allowing the water to absorb the essential compounds. Decoctions are commonly used in herbal medicine and cooking to create concentrated infusions. In addition to herbal remedies, decoctions can be used in making teas or broths. The technique is particularly effective for tougher materials that require more heat and time to release their properties, making it a valuable method in both culinary and medicinal practices.
