Key TCM concepts behind ginseng (Ren Shen)'s properties
In Traditional Chinese Medicine (TCM), ginseng are plants that belong to the 'Tonic herbs for Qi Deficiency' category. Tonic herbs are used for patterns of Deficiency, when one lacks one of the 'Four Treasures' (Qi, Blood, Yin and Yang). Qi tonics are typically sweet and they tend to enter the Spleen and Lungs because these organs are most involved with the production of Qi.
Furthermore ginseng are plants that are Warm in nature. This means that ginseng tend 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 ginseng can help restore a harmonious balance between Yin and Yang.
Ginseng also taste Bitter and Sweet. The so-called "five elements" theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Bitter ingredients like ginseng tend 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 ginseng are thought to target the Spleen, the Heart and the Lung. In TCM the Spleen assists with digestion, blood coagulation and fluid metabolism in the body. In addition to regulating blood flow, the Heart is believed to be the store of the "spirit" which basically refers to someone's vitality. In addition to performing respiration, the Lungs are thought to be a key part of the production chain for Qi and the body fluids that nourish the body.
