In Traditional Chinese Medicine (TCM), Mai Ya belongs to the 'Herbs that relieve Food Stagnation' category. These herbs typically possess digestive and Food moving properties as they relate to the Stomach and Spleen. Some of these herbs are high in digestive enzymes and have varying specific abilities to help with the digestion of food.
Furthermore Mai Ya is Neutral in nature. This means that Mai Ya typically doesn't affect the balance in your body. Balance between Yin and Yang is a key health concept in TCM. Eating too many "Hot" (Yang) ingredients can lead to an imbalance whereby one has a Yang Excess. The inverse is true as well: too many "Cold" (Yin) ingredients can lead to a Yin Excess. The Neutral nature of Mai Ya means that you don't have to worry about that!
Mai Ya also tastes 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. Sweet ingredients like Mai Ya tends 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 Mai Ya is thought to target the Spleen and the Stomach. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. The Stomach on the other hand is responsible for receiving and ripening ingested food and fluids. It is also tasked with descending the digested elements downwards to the Small Intestine.
