There is no such thing as the fastest way to treat a man’s spleen and kidney yang deficiency (deficiency of yang qi in the spleen and kidneys). A man’s spleen and kidney yang deficiency can be diagnosed and analyzed by using proprietary Chinese medicines such as Sengyang capsule and Shengwuga capsule for conditioning. 1. Sengyang capsule: it has the effect of warming the spleen and kidney, and is used to treat the symptoms of lumbar and knee soreness (the feeling of soreness and weakness of the waist and knee) and cold limbs (fear of cold, cold limbs) caused by spleen and kidney yang deficiency. Adverse reactions such as the development of dry mouth may occur after taking the medicine. It is contraindicated for minors, people with yin deficiency and fire exuberance (deficiency of yin essence in the body and hyperactivity of deficiency fire) and pregnant women. 2. Sentinel capsule: It has the effect of benefiting qi and strengthening the spleen (regulating the qi of the spleen and stomach), and also has the effect of tonifying the kidney and tranquilizing the mind. It is used for symptoms such as weakness, lumbar and knee pain and insomnia due to spleen and kidney yang deficiency. Its contraindications and adverse reactions are not clear. When using the drug for treatment, it is necessary to be guided by a Chinese medicine practitioner to recognize the evidence and not to use the drug arbitrarily, so as to avoid adverse consequences.
