Tian Qi is also known as Panax ginseng, and its main effects are to invigorate blood, stop bleeding, and replenish blood. Children should not take Radix Panax notoginseng as it may cause excess Yang energy in children and lead to fire, especially skin pimples, throat inflammation and so on. For children, the human body is a tender limb, and many organs are immature, so there is no need to improve blood circulation through Tian Qi at this time, because the vascular condition of children is very good, and the application of Tian Qi is not beneficial to the body, but more likely to increase the hormonal disorder of the human body, especially the appearance of secondary sexual characteristics in adolescent children, which will cause certain problems. When children are approaching adulthood, that is, between 18-20 years old, if they feel short, they can consider applying a small amount of Tian Qi orally to increase the possibility of height, but otherwise try not to use it.
