Lung cancer patients can take ginseng, but there is a premise that it should be applied selectively. Ginseng is a traditional Chinese medicine, and it is also a medicine to support and strengthen the root, which is useful for fatigue, weakness and low metabolic function of the body caused by many reasons. In the treatment of lung cancer, it is mainly used to improve the immune function, and also has a certain protective and therapeutic effect on the leukopenia caused by radiotherapy, which is related to the ginsenosides in it. However, from the perspective of Chinese medicine, there are different varieties of ginseng, and different varieties have different efficacy, so lung cancer patients should use them according to their own characteristics. Commonly available ginseng is generally warm in nature to replenish the vital energy, including red ginseng and Korean ginseng, which have stronger warming effect on Yang. For patients with lung cancer who have been weak for a long time, easily cough and shortness of breath, they can consider using ginseng or even red ginseng. However, if the lung and stomach yin deficiency is manifested and there is bitterness in the mouth, dry throat and poor sleep, it is appropriate to choose American ginseng. If the manifestation of yin deficiency is more obvious, dry mouth, easy to catch fire, and dry stool, it is not suitable to take ginseng or red ginseng, so it should be used selectively, and it is better to apply it under the guidance of a Chinese medicine doctor.
