Ji Zi Huang is an assistant ingredient in Huang Lian E Jiao Tang. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
In Traditional Chinese Medicine (TCM), Ji Zi Huang belongs to the 'Tonic herbs for Yin Deficiency' category. Tonic herbs are used for patterns of Deficiency, when one lacks one of the 'Four Treasures' (Qi, Blood, Yin and Yang). Yin tonics have a heavy, moist nature. They either nourish the Kidneys and Liver or moisten the Lungs and Stomach. Extreme Yin Deficiency often translates into a 'burn-out', unfortunately more and more common among people today. It is worth mentioning that another great remedy against Yin Deficiency is a lot of rest and sleep; no herb will ever be able to replace this!
Furthermore Ji Zi Huang is Neutral in nature. This means that Ji Zi Huang 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 Zi Huang means that you don't have to worry about that!
Ji Zi Huang 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 Zi Huang 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 Zi Huang is thought to target the Heart and the Kidney. In addition to regulating Blood flow, in TCM the Heart is believed to be the store of the 'Mind' which basically refers to someone's vitality. The Kidneys do not only regulate the urinary system but also play a key role in the reproductive system and the growth and aging process of the body.
Ji Zi Huang is also eaten as food.
