Why should pilose antler be eaten three days before the winter solstice?

The reason why pilose antler should be eaten three days before the winter solstice is because after the winter solstice, the yang spirit begins to rise and the day gradually becomes longer, which is the key solar term for the transformation of yin and yang. At this time, taking pilose antler can better nourish the body.

Pilose antler refers to the ossified young horn of sika deer or red deer, which is a valuable Chinese herbal medicine. Ancient doctors believed that the essence of deer lies in the horn, while velvet antler is the bud of horn, and its qi is not vented, so it is the most powerful for strengthening yang and benefiting blood.
