Deer antler is a warming tonic for kidney yang, which Chinese medicine refers to as a blood and flesh sentient product, unlike other medicines for kidney yang. Because it is an animal medicine, it is closer to the body’s composition, unlike herbal and stone medicines, so its effect of tonifying kidney yang and kidney essence will be very strong. But in general, deer antler is yang, hot and warm, while wolfberry nourishes yin and nourishes the yin of the liver and kidney, so deer antler and wolfberry go together as one yin and one yang, one for yin and the other for yang.
