In Traditional Chinese Medicine (TCM), Pei Lan belongs to the 'Aromatic herbs that transform Dampness' category. This category of herbs resolves a TCM condition called 'Cold Damp Stagnation', especially as it affects the Stomach and Spleen. In modern medicine this often translates into symptoms such as distended chest and abdomen, lack of appetite, nausea and vomiting
As suggested by its category Pei Lan is Neutral in nature. This means that Pei Lan typically doesn't affect the balance in your body. Balance between Yin and Yang is a key health concept in TCM. Eating too many "Hot" (Yang) ingredients can lead to an imbalance whereby one has a Yang Excess. The inverse is true as well: too many "Cold" (Yin) ingredients can lead to a Yin Excess. The Neutral nature of Pei Lan means that you don't have to worry about that!
Pei Lan 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 Pei Lan 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 Pei Lan is thought to target the Spleen, the Stomach and the Lung. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. The Stomach on the other hand is responsible for receiving and ripening ingested food and fluids. It is also tasked with descending the digested elements downwards to the Small Intestine. 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.
Numerous studies have demonstrated that E. fortunei possesses anti-bacterial, anti-oxidant, and anti-diabetic activities, as well as cytotoxicity to human leukemia cells.1
Results indicate that an aqueous extract of E. fortunei is a potential therapeutic herbal product that may be useful for controlling malignant metastatic cancer.1
