In Traditional Chinese Medicine (TCM), Zi Su Ye belongs to the 'Warm/Acrid herbs that release the Exterior' category. Herbs that release the Exterior aim to to treat the early stages of diseases that affect the upper respiratory tract, the eyes, the ears, the nose, the throat or the skin. TCM believes that External diseases such as colds or allergies can only invade the body if the External environment overwhelms our Wei Qi (the TCM version of the immune system). In order to counteract this invasion Warm/Acrid herbs aim to induce sweating by increasing the flow of sweat to our capillary pores. The belief is that this will expel the disease from the body and stop it from invading further.
As suggested by its category Zi Su Ye is Warm in nature. This means that Zi Su Ye tends to help people who have too much 'Cold' in their body, although with less effect than a plant that would be Hot in nature. Balance between Yin and Yang is a key health concept in TCM. Those who have too much Cold in their body are said to either have a Yin Excess (because Yin is Cold in nature) or a Yang Deficiency (Yang is Hot in Nature). Depending on your condition Zi Su Ye can help restore a harmonious balance between Yin and Yang.
Zi Su Ye also tastes Pungent. The so-called 'Five Phases' theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Pungent ingredients like Zi Su Ye tends to promote the circulations of Qi and Body Fluids. That's why for instance someone tends to sweat a lot when they eat spicy/pungent food.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Zi Su Ye is thought to target the Lung and the Spleen. In addition to performing respiration, the Lungs are thought in TCM to be a key part of the production chain for Qi and the Body Fluids that nourish the body. The Spleen on the other hand assists with digestion, Blood coagulation and Fluids metabolism in the body.
Histopathological examination of the rat livers showed that Perilla frutescens extract reduced the incidence of liver lesion.1
Triterpene acids extracted from the leaves of Perilla frutescens all showed a marked anti-inflammatory effect and one compound exhibited strong antitumor-promoting activity in an in vivo two-stage carcinogenesis test of mouse tumor.2
Perilla leaves extract signiﬁcantly suppressed the PCA‐reaction, which was brought about by rosmarinic acid with a partial contribution from some macromolecular compounds. The anti‐allergic titer of rosmarinic acid was more effective than tranilast, which is a modern anti‐allergic drug. Perilla and rosmarinic acid are potentially promising agents for the treatment of allergic diseases.3

Zi Su Ye is also eaten as food. It is used as an ingredient in dishes such as Marinated Perilla Leaves or Kkaennip-jeon (Pan-fried perilla leaves with fillings).
