Sheng Wei San is composed of equal parts of ginseng, maitake and schizandra. 1. Ginseng is the main medicine, which can replenish vital energy (replenish the root energy of the human body), benefit the lungs, generate fluid and stop coughing, and stop sweating. It can treat profuse sweating, shortness of breath, low voice, and tiredness of limbs due to deficiency of qi and yin. 2. Using Ophiopogon as the subject medicine can clear away heat and promote generation of body fluid, moisten the lungs and stop coughing, and at the same time, it is compatible with ginseng, so as to achieve the effect of replenishment of both qi and yin. 3. Using Schisandra chinensis as the auxiliary medicine can benefit Qi and generate fluid (promoting fluid production by tonifying Qi), and astringent Yin fluid to stop sweating, followed by combining with Panax ginseng and Ophiopogon flexuosus, which can not only stabilize the leakage of Qi and fluid, but also restore the depletion of Qi and Yin. This formula can benefit qi and nourish yin (replenish qi and nourish yin fluid), astringent yin to stop sweating (astringent yin fluid to reduce sweating). It can treat excessive sweating, mental fatigue, lethargy, shortness of breath or prolonged coughing, dry cough with little phlegm, shortness of breath and spontaneous sweating (involuntary sweating during the daytime, aggravated by sweating when there is a slight movement) caused by warmth, summerheat, injury to qi and depletion of yin. It should be noted that this formula should not be used for people with both solid evils, as it may encourage solid evils which cannot be easily removed. The medicine needs to be used under the guidance of a doctor and should not be taken blindly by oneself.
