Common TCM formulas in which virgate wormwood are used*:
In Traditional Chinese Medicine (TCM), virgate wormwood are plants that belong 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 Damp that has accumulated in the body. According to TCM Damp 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 virgate wormwood are plants that are Cool in nature. This means that virgate wormwood tend 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 virgate wormwood can help restore a harmonious balance between Yin and Yang.
Virgate wormwood also taste Bitter and Pungent. 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 virgate wormwood 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 Pungent ingredients tend 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 virgate wormwood are thought to target the Gallbladder, the Spleen, the Stomach and the Liver. Similar to modern medicine, in TCM the Gall Bladder stores and releases bile produced by the Liver. It also controls the emotion of decisiveness. The Spleen on the other hand assists with digestion, blood coagulation and fluid metabolism in the body. The Stomach is responsible for receiving and ripening ingested food and fluids. It is also tasked with descending the digested elements downwards to the Small Intestine. The Liver is often referred as the body's "general" because it is in charge of regulating the movements of Qi and body fluids. It also takes a leading role in balancing our emotions.
