Ma Dou Ling is a deputy ingredient in Bu Fei E Jiao Tang. This means it helps the king ingredient(s) treat the main pattern or it serves to treat a coexisting pattern.
In Bu Fei E Jiao Tang, Ma Dou Ling clears Heat and stops the coughing.
In Traditional Chinese Medicine (TCM), Ma Dou Ling belongs to the 'Herbs that relieve coughing and wheezing' category. In TCM Phlegm is a condition of Stagnation of Fluids which tends to start in the Spleen and then goes to the Lungs. If this overly accumulates it thickens and becomes pathological Phlegm. Phlegm, being a form of Stagnation, often starts as being Cool and transforms to Hot as the condition progresses. Herbs that relieve coughing and wheezing treat branch symptoms of this Stagnation and tend to have antitussive, expectorant, diuretic or laxative properties.
Furthermore Ma Dou Ling is Cold in nature. This means that Ma Dou Ling 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 Ma Dou Ling can help restore a harmonious balance between Yin and Yang.
Ma Dou Ling 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 Ma Dou Ling 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 Ma Dou Ling is thought to target the Large intestine and the Lung. In TCM the Large Intestine receives the "impure" parts of the digested food from the Small Intestine, absorbs the remaining fluids and excrete the remainder as feces. 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.
