How about Shen Lingjian Spleen and Stomach Granules? Can I take it for a long time? I saw that the instructions of Kun medicine Shen Lingjian Spleen and Stomach Granule only said that invigorating spleen and stomach can enhance immunity? Chinese medicine believes that the spleen and stomach are the "acquired foundation" and the source of qi and blood metaplasia. Your poor physique from childhood lies in the weakness of the spleen and stomach and the lack of sources of qi and blood. In Huangdi Neijing, it is written that "righteousness should be kept inside, and evil should not be done". Righteousness is what we call immunity now, and it is the composition of essence, which comes from the essence and qi and blood of food metaplasia. So you want to improve your immunity and resist the virus by strengthening your spleen and stomach. Although the instructions of Kunming traditional Chinese medicine Shenlingjian Spleen and Stomach Granule do not directly state that it can improve your immunity, it is really suitable for you. How about Shenling Jianpi Wei Granule? On the basis of the classic ancient prescription Shenling Baizhu Powder, Radix Glehniae is changed into ginseng, which makes the medicine more moist and can be taken for a long time.
