Radix Panax Ginseng can be taken by decoction with water or in pills or powder, according to the doctor’s instruction. Radix Panax Ginseng has the effect of tonifying qi and nourishing yin, clearing heat and generating fluids, and can be used for treating qi deficiency and yin deficiency, deficiency heat and fatigue, coughing, phlegm and blood, internal heat and thirst (internal heat accompanied by symptoms such as eating, drinking and urinating), and dry mouth and throat. 1. Qi deficiency and yin deficiency, deficiency heat and tiredness, coughing, phlegm and blood: American ginseng is sweet, slightly bitter and cool, not only good at replenishing qi and nourishing yin, but also capable of clearing the deficiency fire, so it can be used for those who have both qi and yin injuries and the deficiency fire is prevalent. It can be used in treating heat injury to qi and yin, deficiency heat and tiredness, excessive sweating and thirst, or chronic cough and lung deficiency, qi and yin injuries, dry cough with little phlegm, shortness of breath and spontaneous sweating (involuntary sweating during the daytime, aggravated by sweating with a little movement), and is often used with maitake, schizandra and other medicines to replenish qi and nourish yin. 2. Internal heat and thirst, dry mouth and throat: American ginseng tonifies qi and nourishes yin, clears deficiency fire and generates fluid to quench thirst (promoting fluid production to relieve thirst). It is suitable for those who suffer from thirst due to deficiency of yin or deficiency of both qi and yin (deficiency of both qi and yin). For treating thirst due to Yin deficiency with internal heat, it is combined with fresh Radix Rehmanniae Praeparata, fresh Dendrobium Officinale and fresh Ophiopogonis to clear heat and nourish Yin, and to generate fluids to quench thirst. American ginseng should not be used together with quassia; the precaution is that it should not be used by people with deficiency and decline of middle yang. If you need to use the drug American ginseng, be sure to consult a Chinese medicine practitioner to guide the use of medication, do not use the drug arbitrarily.
