There is no “astragalus bubble water does not fire with the best” this statement, according to the real fire or false fire identification to choose different drugs to match, such as can be with heat-clearing drugs gardenia, honeysuckle, Huang Huanglian, Scutellaria and other collocation, or with nourishing yin class of drugs maitake, bamboo and so on collocation. “Fire” is a folk saying. Chinese medicine generally believes that “fire” can be divided into two categories: “real fire” and “false fire”. The real fire needs to clear heat and fire, and the virtual fire needs to nourish yin and fire. Astragalus is slightly warm in nature, sweet in taste, and belongs to the lung and spleen meridians. It has the effects of tonifying qi and elevating yang, fixing the surface to stop sweating (stopping sweating by consolidating the surface of the muscle), inducing diuresis to reduce swelling, generating fluids to nourish the blood and promoting stagnation and paralysis (making the paralyzed meridians open up). Astragalus can be used for treating qi deficiency and weakness, loose stools, prolonged diarrhea and prolapse of the anus, blood in the stool, leakage of menstruation (excessive menstruation or more than a few drops), sweating due to deficiency of the surface (due to the weakness of the surface of the muscle and frequent natural sweating), edema due to deficiency of the qi, thirst due to internal heat (fever accompanied by excessive eating, drinking, urination, and other symptoms), and atrophy due to deficiency of the blood. Because of the slightly warm nature of astragalus, but also has the effect of tonifying qi and yang, so the actual heat, dampness and heat, yin deficiency of the patient to take the water is easy to cause heat evidence. Solid heat can be matched with heat-clearing, fire-dissolving and detoxifying drugs such as gardenia, honeysuckle, etc.; damp heat can be matched with heat-clearing and dampness-drying drugs such as Huanglian, Scutellaria baicalensis, etc.; yin deficiency can be matched with yin-supporting drugs such as maitake, bamboo, etc.. When taking astragalus and other matching drugs, it is recommended to consult with a traditional Chinese medicine doctor first, follow the doctor’s instructions to take, not self-medication.
