Platostoma palustre, commonly as Chinese mesona, is a species of plants belonging to the genus Platostoma of the mint family. The species grows extensively in East Asia such as south east China and Taiwan preferring ravines, grassy, dry, and sandy areas. The plants are from 15–100 cm high with hairy stems and leaves. The leaves are tear-drop shaped and serrated.
Use, cultivation and processingEdit
P. palustre is cultivated on flat ground or areas with a slight slope. In Taiwan, this plant is often grown under fruit trees in fruits orchards as a secondary crop. The plant is processed by harvesting all the aerial portions above the root. The portions are then partially dried and piled up in order to allow them to oxidize until they have darkened. After the oxidation, they are then thoroughly dried for sale.
