Too much ginseng may lead to mouth sores, mouth ulcers, nosebleeds and dry stools. Ginseng is an excellent tonic with the effects of tonifying the vital energy (replenishing the body’s root qi), tonifying the spleen and lungs, and generating fluids to quench thirst (promoting the production of fluids to relieve thirst). Its effect of tonifying the vital energy can be used to treat peripheral fatigue caused by hemorrhage, severe vomiting and diarrhea, and can restore physical strength. It also has a soothing effect on weakness and bloating caused by spleen and lung qi deficiency. Ginseng can also relieve dryness of the mouth and tongue and thirst caused by heat illnesses that injure the yin. Healthy people should take ginseng with caution, as various symptoms of heat illness will appear after taking it, such as sores on the mouth and tongue, ulcers in the mouth, nosebleeds, and dry stools. Taking it by patients with damp-heat in the spleen and stomach (spleen and stomach feeling damp-heat evil) will lead to mouth ulcers and dry stools. Under the premise of diagnosis and treatment, there will be no adverse reaction when taking it, and ginseng should not be taken by people with various kinds of solid evidence or damp-heat constitution. Patients are forbidden to take ginseng during the period of taking ginseng, such as quinoa and wulingzhi. It is recommended to take ginseng under the guidance of a doctor to avoid adverse effects.
