Tooth-marked tongue caused by spleen qi deficiency can be treated with red ginseng, which can benefit qi and strengthen the spleen (regulating the qi of the spleen and stomach). However, the tongue may also be physiologic. If the tongue is not big with slight teeth marks and no other discomfort, physiologic tongue is more likely and does not need to be treated with red ginseng. However, if the tongue is fat and has teeth marks, it is mostly considered to be the congestion of cold and dampness or the deficiency of Yang and water, and red ginseng is also not recommended. Red ginseng is sweet, slightly bitter and warm in nature. It belongs to the spleen, lung, heart and kidney meridians. It has the effects of tonifying the vital energy (replenishing the body’s root qi), restoring the pulse and stabilizing shedding (restoring the normal pulse and preventing the shedding of substances), and benefiting the qi to regulate blood (preventing bleeding by tonifying the qi). It is used in treating body weakness and desire for detachment, cold limbs and weak pulse, failure of Qi to take in blood, and discharging blood in the form of metrorrhagia (excessive menstrual flow or dripping). It should be noted that it should not be used in conjunction with quinquefoil and wulingzhi. The specific adverse effects of Red Ginseng are not clear, it is recommended to consult a doctor before using the drug.
