The correct way to drink astragalus powder in water is to take an appropriate amount of astragalus powder and take it directly with boiled water. Astragalus powder is a powder made from ground astragalus, which has the same effects as astragalus, but Chinese medicine mainly works through decoction, so drinking it in water may affect its efficacy because of the limited release of active ingredients. Astragalus functions to replenish qi, strengthen the spleen, elevate yang and lift up sunken organs, diuretic, reduce swelling and stop sweating. Astragalus powder can be used to improve symptoms such as loss of appetite, tiredness (fatigue), yellowish color (yellow and lusterless), etc. due to deficiency of qi, but it should be noted that it should not be taken during the patient’s cold. The drug should be taken under the guidance of a doctor.
