Anorexia, lethargy, and indigestion can be taken with red ginseng if they are caused by qi deficiency. You should consult your physician for specific medication. Fatigue is mostly considered to be caused by qi deficiency in Chinese medicine, while anorexia and dyspepsia are all manifestations of spleen and stomach dysfunction, so the appearance of the above symptoms is mainly related to spleen qi deficiency. For this syndrome, medications that benefit qi and strengthen the spleen (regulating the qi of the spleen and stomach) can be used. Red ginseng belongs to the category of tonic drugs in traditional Chinese medicine, which has the effects of tonifying the vital energy (replenishing the body’s root qi), strengthening the spleen and lungs (strengthening the functions of the spleen and lungs), generating fluids and quenching thirst (promoting the production of fluids to alleviate thirst), and tranquillizing the mind and stimulating the intellect (stabilizing the mind and promoting intellectual development), so it can be used to treat symptoms caused by deficiency of the Spleen-Qi. However, this drug is strictly prohibited to be used together with quinoa and wulingzhi. Consultation with a doctor is recommended for specific use.
