In general, deer antler is not suitable for children because it has a significant effect on kidney yang and is considered by Western medicine to contain sex hormones. If children eat deer antler, it can lead to precocious puberty. Precocious puberty in children often leads to early appearance of secondary sex characteristics and early bone age in children, which can lead to psychological development and can affect the final height of children if the bone age closes early, so it is not suitable for healthy children to eat deer antler under normal circumstances. If a child has obvious symptoms of kidney yang deficiency, such as short stature or if the child is often cold or frightened, deer antler can also be taken to nourish the kidney yang.
