Mo han lian is a king ingredient in Er Zhi Wan. Like the name indicates, it means it has more power than other ingredients in the formula.
In Er Zhi Wan, Mo han lian is sweet, sour, and cold. It supplies the Essence, nourishes the Yin and cools the Blood to stop bleeding. Together with Nu Zhen Zi it nourishes the Yin aspects of the Liver and the Kidneys, without being cloying.
In Traditional Chinese Medicine (TCM), Mo han lian 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 Mo han lian is Cold in nature. This means that Mo han lian 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 Mo han lian can help restore a harmonious balance between Yin and Yang.
Mo han lian also tastes Sour and 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. Sour ingredients like Mo han lian helps with digestion and restrain abnormal discharges of Fluids from the body, such as diarrhea or heavy sweating. On the other hand Sweet ingredients tend 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 Mo han lian is thought to target the Kidney and the Liver. According to TCM, 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. The Liver on the other hand 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.
