Abstract
Medicinal plants are dried by applying microwave power to plant materials in a chamber under reduced pressure to reduce the moisture content of the plant materials without significantly reducing (oxidizing) the concentration of active medicinal component in the dried plant materials and thereby produce a dried medicinal plant product which more closely approaches the medicinal properties of the fresh plant than those of dried products produced by conventional air drying processes.
