Key TCM Concepts

In Traditional Chinese Medicine (TCM), Ya Ma Zi belongs to the 'Laxative herbs that drain downward' category. The herbs in this category are those whose main purpose is to treat constipation. They're called 'laxative' because they're often rich in oils. This allows them to lubricate the Intestines in order to help it remove the stools from the body.

 

Furthermore Ya Ma Zi is Neutral in nature. This means that Ya Ma Zi 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 Ya Ma Zi means that you don't have to worry about that!

 

Ya Ma Zi 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 Ya Ma Zi 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 Ya Ma Zi is thought to target the Stomach, the Large intestine and the Liver. 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 Large Intestine on the other hand receives the "impure" parts of the digested food from the Small Intestine, absorbs the remaining fluids and excrete the remainder as feces. The Liver 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.
