Astragalus has the effect of tonifying qi and promoting yang, moving stagnation and paralysis (to make the paralyzed meridians smooth), fixing the surface and stopping sweating (to stop sweating by consolidating the surface of the muscle), reducing water and swelling, astringing sores and promoting the growth of muscle (to help sores heal faster and promote the growth of new flesh), and toxin draining (to drain the body of pus and toxins). But the role of water is limited, can not replace the therapeutic role of drugs. Astragalus is sweet, slightly warm, and belongs to the spleen and lung meridian, with the function of tonifying qi, which can improve the tiredness and weakness caused by spleen qi deficiency, and loose stools caused by poor food (feces are thin and unshaped). Because it has the power to raise the Yang, it is especially good for the sagging of the internal organs caused by the sinking of the middle qi (deficiency of the spleen and stomach qi, with the appearance of the internal organs falling down), prolonged diarrhea and prolapse of the anus, and so on. Astragalus can replenish qi in order to promote the operation of qi, blood and fluid, and improve edema caused by qi deficiency. It can also improve spontaneous sweating (involuntary sweating during the day, aggravated by the slightest movement of sweating) and coughing caused by lung deficiency. To move stagnation and promote paralysis, astringent sores and muscle growth, and to support toxin and pus drainage, this drug tonifies Qi to promote paralysis and Qi to move blood. This drug is often used in the treatment of post-stroke and paralysis caused by deficiency of qi and blood stagnation, and loss of nourishment of tendons and skin. And this drug can make the positive qi vigorous and push the evil qi out, which can be used to treat carbuncle and gangrene (a kind of poisonous sores, acute suppurative disease occurring on the body surface, limbs and internal organs) which is long ulcerated but not converged, or difficult to be putrefied and difficult to be ulcerated. Astragalus as a traditional Chinese medicine, treatment of disease application, need to be used under the guidance of a physician, not blindly take. If there is any discomfort, timely medical treatment should be sought.
