In Traditional Chinese Medicine (TCM), Qian Dan belongs to the 'Herbs for external application' category. Like the name indicates, this category of herbs is used mostly for external application in the form of powders, pastes or ointments. As such they are used to treat trauma, inflammation, swelling, bruises, bleeding, pain and so forth.
Furthermore Qian Dan is Cool in nature. This means that Qian Dan 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 Qian Dan can help restore a harmonious balance between Yin and Yang.
Qian Dan also tastes Pungent. 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. Pungent ingredients like Qian Dan tends 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 Qian Dan is thought to target the Spleen, the Heart and the Lung. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. In addition to regulating Blood flow, the Heart is believed to be the store of the 'Mind' which basically refers to someone's vitality. 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.
