In Traditional Chinese Medicine (TCM), Bei Sha Shen belongs to the 'Tonic herbs for Yin Deficiency' category. Tonic herbs are used for patterns of Deficiency, when one lacks one of the 'Four Treasures' (Qi, Blood, Yin and Yang). Yin tonics have a heavy, moist nature. They either nourish the Kidneys and Liver or moisten the Lungs and Stomach. Extreme Yin Deficiency often translates into a 'burn-out', unfortunately more and more common among people today. It is worth mentioning that another great remedy against Yin Deficiency is a lot of rest and sleep; no herb will ever be able to replace this!
Furthermore Bei Sha Shen is Cool in nature. This means that Bei Sha Shen tends to help people who have too much 'Heat' in their body, although with less effect than a plant that would be Cold in nature. Balance between Yin and Yang is a key health concept in TCM. Those who have too much Heat in their body are said to either have a Yang Excess (because Yang is Hot in nature) or a Yin deficiency (Yin is Cold in Nature). Depending on your condition Bei Sha Shen can help restore a harmonious balance between Yin and Yang.
Bei Sha Shen also tastes Bitter and Sweet. 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. Bitter ingredients like Bei Sha Shen tends to have a cleansing action on the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements. On the other hand Sweet ingredients tend to slow down acute reactions and detoxify the body. They also have a tonic effect because they replenish Qi and Blood.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Bei Sha Shen is thought to target the Lung and the Stomach. 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 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.
