Severe Kidney-Yang deficiency can be recovered in about 1-6 months with proper treatment and medication. Supplementation of kidney yang is best carried out in winter so that the effect will be more satisfactory. For medicines to regulate kidney yang, the more common ones are Jin Gui Ren Qi Pill, Yu Gui Pill and calcium supplements, strong body medicines, like the more popular Ren Bao tablets and so on, all of which can regulate kidney yang. Personally, I would recommend taking a small amount of wine by Zi He Che and Cordyceps sinensis, etc., orally every day, which is very beneficial to the regulation of kidney yang. Men have a greater need for kidney yang, which is mainly reflected in their sex life. For impotence and premature ejaculation caused by kidney yang deficiency, it will take a long time to adjust, usually not only with drugs, but also through spiritual therapy to save.
