Astragalus has the effects of tonifying Qi and elevating Yang (tonifying Qi to elevate Yang Qi), consolidating the surface and stopping sweating (stopping sweating by consolidating the surface of the muscle), inducing diuresis and eliminating swelling (relieving urination and eliminating edema), generating fluids and nourishing blood (replenishing the body’s water and blood), promoting stagnation and paralysis, supporting toxin and draining pus (draining pus and toxin from the body), and astringing sores and regenerating the muscle (helping sores to heal more quickly, and promoting the growth of new flesh). Astragalus is sweet in flavor and slightly warm in nature. Attributed to the lung and spleen meridians. It is used for qi deficiency and fatigue, loose stools (thin and unformed feces), sagging of the middle qi (deficiency of the spleen and stomach qi, with manifestations such as falling of the internal organs), prolonged diarrhea and prolapse of the anus, blood in the stools and leakage of blood (excessive menstrual flow or dribbling), sweating from the surface of the skin (due to the weakness of the muscular surface and frequent and natural sweating), and edema due to deficiency of the qi. Astragalus can also be used for internal heat and thirst (internal fever accompanied by symptoms such as excessive eating, drinking and urination), blood deficiency and yellowing, hemiplegia (one side of the limbs cannot move freely), paralysis and numbness, carbuncle and gangrene (a kind of venomous sores, occurring in the surface of the body, the limbs, the internal organs of the acute suppurative disease) is difficult to ulcerate, and the ulceration does not converge for a long time. Note that it is not suitable to be used when there is an abundance of evil on the surface, internal stagnation, yin deficiency and hyperactivity (deficiency of yin fluid and hyperactivity of yang qi), or when heat and poison are still present at the beginning of the ulcer or after ulceration. If there is any discomfort, it is recommended to go to the hospital in time and use the medicine under the doctor’s guidance.
