1, patients with poor spleen and stomach function are not suitable. Although Liuwei Dihuang Pill is a medicine for nourishing yin, people with poor stomach function will hinder digestive function after eating it. Therefore, even if you are a kidney-yin deficiency, but the spleen and stomach function is not good, it is not recommended to take it.

2. Those who have no symptoms of kidney yin deficiency are not suitable. The symptoms of kidney yin deficiency are soreness of the waist and knees, vexation, dizziness and tinnitus, etc. Although Liuwei Dihuang Pill has the function of tonifying the kidney, healthy people will not have any side effects if they eat less, but if they take it for a long time, they are likely to have symptoms such as full abdomen and not wanting to eat.

3. Patients with severe kidney-yang deficiency are not suitable. The manifestations of kidney-yang deficiency are pale complexion, cold waist and knees, and weak constitution. Many patients with erectile dysfunction think that it is caused by kidney deficiency, and then they take Liuwei Dihuang Pills, but they often get the opposite effect, because the kidney is only an organ of the urinary system and has nothing to do with sexual function.

4. Healthy people For normal people, if there are no obvious symptoms of kidney yin deficiency, it is not suitable to take Liuwei Dihuang Pill. People with weak spleen and stomach can choose to eat it half an hour after meals, so as to avoid the damage caused by frequent use to the gastrointestinal tract. Also, the eating method of Liuwei Dihuang Pill should change according to the changes of health, and it cannot be taken daily like vitamins.
