Which method of using plant material involves steeping in hot water?

The method involving steeping plant material in hot water is known as infusion. This technique is commonly used for preparing herbal teas or other plant-based beverages. During an infusion, the plant material, typically delicate parts such as leaves or flowers, is placed in hot water for a short period. The hot water extracts the beneficial compounds from the plant material, allowing for the release of flavors, aromas, and medicinal properties into the liquid.

This method differs from decoction, where tougher plant parts such as roots or bark are boiled for a longer time to extract their medicinal properties. Extraction usually involves the use of solvents, such as alcohol or oil, to draw out active compounds, while maceration refers to soaking plant material in a solvent at room temperature for an extended period to allow for a gentle extraction. Each of these methods has its unique applications and is suited to different types of plant materials.
