Huangdi Neijing says: Yang in spring and summer, Yin in autumn and winter. In winter, I mainly take drugs that nourish yin and moisten dryness. However, after the sun is born (that is, after the winter of solstice), medicinal materials can be used to raise yang, and the effect is the best at this time.

There are many drugs to help yang, which can be made into soup or soaked into medicinal liquor. Suggestion: soak ginseng and pilose antler in wine ~ ~ ~
