According to the Compendium of Materia Medica, various vitamins in green onions can ensure the normal secretion of human hormones and effectively stimulate sexual desire, thus "strengthening yang and nourishing yin". I often stir-fry green onions, and then soak ginseng, medlar and black tea in water every day. The effect is quite good, because it is simple to operate and has no natural side effects. If I continue to take it, it will fundamentally improve renal function, warm kidney and strengthen yang, and greatly replenish vitality, and the price is not expensive!
