Really, I've looked into this before. Saffron wine not only has the basic functions of promoting blood circulation, removing blood stasis, cooling blood and detoxicating, relieving depression, calming nerves, beauty beauty, preventing cardiovascular and cerebrovascular diseases, and regulating liver and kidney functions, but also can tonify kidney, produce sperm, invigorate spleen and qi, nourish blood and activate collaterals. It is mainly used to treat kidney deficiency and blood deficiency, dizziness and lumbago, anorexia, insomnia, irregular menstruation, etc. For saffron products, I recommend the brand Huayurong.
