The difference between red ginseng and Radix et Rhizoma Ginseng is that red ginseng can be used for treating deficiency of the body, cold limbs and weak pulse, while Radix et Rhizoma Ginseng can be used for treating deficiency of the spleen and lungs, poor appetite and tiredness, coughing and asthma. Red ginseng has the effects of tonifying vital energy, restoring the normal pulse and preventing deficiency, benefiting qi and blood ingestion (preventing bleeding by tonifying qi), which is beneficial to the treatment or improvement of deficiency, cold limbs and weak pulse, qi not ingesting blood, and discharging blood from menstruation, but it is not suitable to be used with quatrefoil and wulingzhi. Dangshen is good for tonifying the spleen, benefiting the lungs, nourishing the blood and promoting the production of fluids, which is good for treating or improving the symptoms of spleen and lung qi deficiency, poor appetite and tiredness, coughing and asthma, insufficient qi and blood, yellowish color, palpitations, shortness of breath, thirst and internal heat (internal heat accompanied by symptoms such as overeating and excessive drinking and urination), but it should not be used in conjunction with quatu. It should be noted that Chinese medicine emphasizes the use of Chinese herbs for evidence-based purposes, so Chinese herbs should be used singly or in combination with Chinese herbs under the guidance of the doctor’s evidence-based guidance, and should not be used blindly without authorization.
