Key TCM concepts behind Ji nei jin's properties

In Traditional Chinese Medicine (TCM), Ji nei jin 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 Ji nei jin is Neutral in nature. This means that Ji nei jin 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 Ji nei jin means that you don't have to worry about that!

Ji nei jin 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 Ji nei jin 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 Ji nei jin is thought to target the Bladder, the Spleen, the Stomach and the Small intestine. In TCM the impure water collected by the Kidneys that cannot be used by the body is sent to the Bladder for storage and excretion as urine. The Spleen on the other hand assists with digestion, Blood coagulation and Fluids metabolism in the body. 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. Like the Stomach, the Small Intestine has a digestive role, extracting the "pure" part of what we injest to the Spleen and the "impure" down to the Large Intestine.
