Sheng Mai San is a 3-ingredient Chinese Medicine formula with Ginseng (Ren Shen) as a principal ingredient.
Invented in Yuan Dynasty, it belongs to the category of formulas that tonify Qi. Its main actions are: 1) augments Qi and 2) supplies the Yin.
In Chinese Medicine health conditions are thought to arise due to "disharmonies" in the body as a system. These disharmonies are called "patterns" and the very purpose of herbal formulas is to fight them in order to restore the body's harmony.
In this case Sheng Mai San is used by TCM practitioners to fight patterns like Lung Yang Deficiency. From a Western Medicine standpoint, such patterns can give rise to a range of conditions such as coronary artery disease, acute myocardial infarction or myocarditis for instance.
On this page, after a detailed description of each of the three ingredients in Sheng Mai San, we review the patterns and conditions that Sheng Mai San helps treat.
Ren Shen is a king ingredient in Sheng Mai San. Like the name indicates, it means it has more power than other ingredients in the formula.
Part used: Dried root

Ren Shen strongly tonifies the source Qi and strengthens the Qi so as to generates Body Fluids. The depute herb Dwarf lilyturf root is more on creating the Fluids directly. The combination of the two herbs give a strong effect on Body Fluids generating. The Lung Qi is replete when the source Qi is strong. Therefore, the Lungs can easily regulates the interstices and pores so as to contain Body Fluids between the skin and muscles. The herb also calms the spirit. This is a well balanced formula. The key herb tonifies, the deputy clears, and the assistant restrains leakage.
Mai Dong is a deputy ingredient in Sheng Mai San. This means it helps the king ingredient(s) treat the main pattern or it serves to treat a coexisting pattern.
Part used: Dried root tuber

Mai Dong nourishes the Yin and moistens the
Lungs. It also supports the Stomach by generates Body Fluids directly. While the key herb Ginseng of the formula creates Fluids indirectly. The combination of the two herbs give a strong effect on generating Body Fluids. The herb can also clears Heart Heat or Fire to eliminate irritability.
Wu Wei Zi is an assistant ingredient in Sheng Mai San. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
Part used: Dried ripe fruits

Wu Wei Zi prevents the leakage of Lung Qi and generates Kidneys Body Fluids. By tonifying the Kidneys, it also checks
the excessive Qi ascent. In working with the deputy herb Dwarf lilyturf root, it is very effective in generating Body Fluids. Together with
the key herb Ginseng, it helps to restore the injured Qi and Yin.
It's important to remember that herbal formulas are meant to treat patterns, not "diseases" as understood in Western Medicine. According to Chinese Medicine patterns, which are disruptions to the body as a system, are the underlying root cause for diseases and conditions.
As such Sheng Mai San is mostly used to treat the pattern "Lung Yang Deficiency" which we describe below.
But before we delve into Lung Yang Deficiency here is an overview of the Western conditions it is commonly associated with:
Again it wouldn't be correct to say "Sheng Mai San treats coronary artery disease" for instance. Rather, Sheng Mai San is used to treat Lung Yang Deficiency, which is sometimes the root cause behind coronary artery disease.
