Sheng Wei Drink is effective in relieving premature beats caused by deficiency of qi and yin, and it is recommended that patients who need it should consult a doctor in time. According to traditional Chinese medicine, premature beats belong to the categories of “palpitations (rapid heartbeat, often accompanied by panic)” and “palpitations of the heart (rapid heartbeat, panic)”, which are generally caused by the deficiency of the heart and spleen (weakness of the heart and the spleen), deficiency of yin and exuberance of fire (deficiency of yin and essence in the body, resulting in the hyperactivity of deficiency and fire), Heart Yang is not vibrant, etc. It usually manifests as rapid beating in the heart, panic and restlessness, and is accompanied by chest paralysis and heart pain, insomnia and forgetfulness. Sheng Wei Drink is composed of Red Ginseng, Ophiopogon and Schisandra, in which Red Ginseng benefits Qi and generates fluid (promoting fluid production by tonifying Qi); Ophiopogon nourishes Yin and clears the lungs (dispelling lung-heat by nourishing the fluid in the lungs) and generates fluid; and Schisandra astringes the lungs (astringing Lung-Qi) to stop coughing and sweating. The combination of the three herbs results in the efficacy of Sheng Wei Drink in benefiting the qi and restoring the veins (by replenishing the qi to make the veins full and smooth), nourishing the yin and generating fluids, and is commonly used clinically for treating palpitations, shortness of breath, and spontaneous sweating (involuntary sweating during the daytime, aggravated by the slightest movement of sweating), etc., caused by deficiency of both qi and yin. It should be used with caution in cases of weakness of the spleen and stomach, vomiting and diarrhea, bloating and loose stools (thin and unformed feces), and coughing with excessive phlegm. This medicine should be taken under the supervision of a doctor.
