In ancient times, when using herbs to treat diseases, one would select clean herbs, chew them into pieces, decoct them in water, and take the liquid. This process was called "ju" (chewing/crushing). Later generations used knives and mortars to finely chop the herbs and sieved them with bamboo screens for uniformity.
Herbs possess different properties regarding the density of their qi and flavor, ascending/descending or floating/sinking movements, tonifying/draining effects, and therapeutic indications. These vary greatly. The following details these characteristics, as well as methods for selection, processing, and compounding.
