Shi Jue Ming is an assistant ingredient in E Jiao Ji Zi Huang Tang. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
In Traditional Chinese Medicine (TCM), Shi Jue Ming belongs to the 'Herbs that pacify Internal Liver Wind and stop Tremors' category. These herbs are used to treat so-called 'hyperactive Liver Yang'. Concretely this translates into high blood pressure as well as seizures, spasms, convulsions, dizziness and vertigo. These herbs often seem to have a powerful antispasmodic effect on the nervous system.
Furthermore Shi Jue Ming is Cold in nature. This means that Shi Jue Ming 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 Shi Jue Ming can help restore a harmonious balance between Yin and Yang.
Shi Jue Ming also tastes Salty. 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. Salty ingredients like Shi Jue Ming tends to have a draining effect in the body because they clear accumulations, remove Phlegm and soften hard lumps.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Shi Jue Ming is thought to target the Kidney, the Liver and the Lung. 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. In addition to performing respiration, the Lungs are thought in TCM to be a key part of the production chain for Qi and the Body Fluids that nourish the body.
