Qu Mai is a king ingredient in Ba Zheng San. Like the name indicates, it means it has more power than other ingredients in the formula.
In Ba Zheng San, Qu Mai bitter and cold. It enters the Blood to invigorate the Blood and is particularly useful in treating painful urinary dribbling with Blood. It also directs Heart Fire and Heat downward, unblocks the Small Intestine, expels Damp Heat from the Bladder, and is an important herb for treating dribbling disorders.
In Traditional Chinese Medicine (TCM), Qu Mai belongs to the 'Herbs that drain Dampness' category. These herbs are typically diuretics, meaning that they promotes the increased production of urine in order to remove Dampness that has accumulated in the body. According to TCM Dampness accumulates first in the lower limbs, causing edema and impaired movement. From there, if unchecked, it can move upward and impair digestion and eventually the respiratory system.
Furthermore Qu Mai is Cold in nature. This means that Qu Mai typically helps people who have too much 'Heat' in their body. 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 Qu Mai can help restore a harmonious balance between Yin and Yang.
Qu Mai also tastes Bitter. 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 Qu Mai tends to have a cleansing action on the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Qu Mai is thought to target the Bladder, the Heart and the Small intestine. In TCM the impure water collected by the Kidneys that cannot be used by the body is sent to the Bladder for storage and excretion as urine. In addition to regulating Blood flow, the Heart is believed to be the store of the 'Mind' which basically refers to someone's vitality. Like the Stomach, the Small Intestine has a digestive role, extracting the "pure" part of what we injest to the Spleen and the "impure" down to the Large Intestine.
