Sheng Mai San is used to treat Lung Yang Deficiency

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:

Coronary artery disease Acute myocardial infarction Myocarditis Heart arrhytmias Congestive heart disease Chronic bronchitis Pulmonary tuberculosis Cardiopulmonary disease

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.

Now let's look at Lung Yang Deficiency, a pattern that TCM practitioners commonly treat with Sheng Mai San.

The Lungs is a so-called "Zang" Organ. Learn more about the Lungs in Chinese Medicine

Lung Yang Deficiency

This pattern leads to symptoms such as poor appetite, frequent urination, coughing with copious clear thin sputum and cold limbs. Patients with Lung Yang Deficiency typically exhibit slow (Chi), slowed-down (Huan) or wiry (Xian) pulses.

The general symptom of Lung Yang Deficiency is coughing and wheezing with profuse sputum, but the sputum is thin and watery. There is also Cold characters such as cold limbs and back, feeling of cold and easy to get cold or flu. It is because the lacking of Yang fails to warm the body.
