Yin deficiency and exuberant fire can eat American ginseng. Yin deficiency and exuberant fire is caused by insufficient yin fluid in the human body, which leads to hyperactive fire, mainly manifesting symptoms such as dizziness, tinnitus, hot flashes (a burst of fever), etc. American ginseng has the effect of tonifying qi and nourishing yin, and can be used for night sweating (sweating abnormally after falling asleep, but the sweating stops after waking up), hot flashes and other symptoms caused by yin deficiency and exuberant fire. Radix Panax Ginseng is cool and tonic in nature, which can both tonify Qi and clear away heat, nourish Yin and generate fluid, making it a clear and nourishing product among Qi tonic medicines. It can be used together with Fructus Schisandrae chinensis and Fructus Chuanbei Mu if it is used to treat dry cough with little phlegm, chest tightness and shortness of breath, dry mouth and throat due to deficiency of yin and lung heat. It is often used with watermelon cucumber and maitake to treat stomach heat and fluid injuries such as excessive body heat and sweat, thirst and heartburn, short and red urine, and tiredness and less gas. Radix Panax Ginseng is strong in replenishing qi, similar to ginseng but a little weaker; it can also clear fire, nourish yin and promote the production of body fluid. It can be used together with Maitake and Schizandra for those who have deficiency of vital energy and depletion of yin and fluid, such as mental fatigue, shortness of breath, spontaneous sweating (involuntary sweating during the daytime, aggravated by the slightest movement of sweating), hot and sticky, heartburn and thirst, and weakness with a thin pulse (the pulse becomes narrower and finer, and the rate is accelerated). However, it should be noted that the effect of a single Chinese medicine is weak, and other medicines can be used together under the guidance of TCM practitioners to achieve the best therapeutic effect. This drug should not be used together with Veratrum; it is contraindicated in cases of deficiency of middle Yang, obstruction of cold and dampness, and depletion of Qi and fire. When using Radix et Rhizoma Ginseng, it is recommended to consult a professional doctor and use it under the doctor’s guidance to avoid adverse reactions.
