Astragalus in water has the effect of strengthening the spleen, benefiting the qi and strengthening the epidermis. However, the efficacy of drinking water cannot be equated with the efficacy of Chinese medicine in curing diseases, and should be used under the guidance of a Chinese medicine practitioner for diagnosis. Astragalus is sweet in flavor and slightly warm in nature; it belongs to the spleen and lung meridian; it has the effect of replenishing qi and raising yang (replenishing qi in order to make yang qi rise), benefiting the guards and consolidating the surface, supporting the toxicity of the muscle (discharging poisonous evils and promoting the growth of the muscle and healing of wounds), and inducing diuresis to reduce edema. It can be used for treating spleen qi deficiency, lung qi deficiency, qi deficiency and spontaneous sweating (involuntary sweating during the daytime, aggravated by sweating with slight movement), edema, qi and blood deficiency, sores and ulcers that are difficult to be ulcerated and putrefied, or difficult to be converted for a long time (traumatic injury, sores and pus that have not been healed for a long time), and so on. Adverse effects of this product are not clear. People who have strong veins with solid symptoms, fever, sores at the beginning of ulcers, or those who are still full of heat and toxins after ulceration are not suitable for applying Astragalus. Drinking water with Chinese herbal medicine has limited active ingredients and generally fails to achieve the effect of treating diseases. If the patient is not feeling well and has a need for treatment, it is recommended that under the guidance of a Chinese medicine practitioner, the medication should be used reasonably and correctly to avoid adverse reactions and delays in formal treatment.
