In Traditional Chinese Medicine (TCM), Peng Sha 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 Peng Sha is Cool in nature. This means that Peng Sha 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 Peng Sha can help restore a harmonious balance between Yin and Yang.
Peng Sha also tastes Salty 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. Salty ingredients like Peng Sha tends to have a draining effect in the body because they clear accumulations, remove Phlegm and soften hard lumps. 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 Peng Sha is thought to target the Stomach 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. 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.
