In Traditional Chinese Medicine (TCM), bletilla rhizomes are plants that belong to the 'Herbs that stop bleeding' category. Like the name indicates these herbs tend to have hemostatic properties, meaning that they help stop various types of hemorrhages and echymosis. Unlike other herbs they often tend to be used externally.
Furthermore bletilla rhizomes are plants that are Cold in nature. This means that bletilla rhizomes typically help 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 bletilla rhizomes can help restore a harmonious balance between Yin and Yang.
Bletilla rhizomes also taste 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 bletilla rhizomes 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 bletilla rhizomes are thought to target the Stomach, the Liver and the Lung. In TCM 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 on the other hand is often referred as the body's "general" because it is in charge of regulating the movements of Qi and the Body Fluids. It also takes a leading role in balancing our emotions. 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.
