Perilla is used as a medicine for the dried leaves of Perilla frutescens, which is pungent in flavor and warm in nature. It belongs to the lung and spleen meridians. It has the effects of relieving cold (removing cold from the surface of the muscles), moving qi and harmonizing the stomach (regulating the stomach and internal organs by promoting the operation of qi). It can be used to treat wind-cold cold, cough, pregnancy vomiting, fish and crab poisoning. As perilla leaves are pungent and warm, they do not have the effect of attacking stasis and draining blood, and do not hurt or break the blood, so they can usually be consumed during menstruation.
