I'll just explain my personal opinion for your reference: I strongly disapprove of using supplements for adult children, except for clearing, regulating and supplementing. Unless children are weak in qi and blood due to some diseases or genetic factors, it will be counterproductive to provide them with food or medicine, and precocity is only one of the disadvantages. There are several specific stages in the growth and development of children. As long as children have good habits of work and rest, ensure the nutritional balance of daily food, and properly supplement sufficient calcium, iron, zinc and various vitamins, it is enough to ensure the healthy and normal development of children. Of course, although your child has eaten the bone-and-bone tea of Cordyceps sinensis, after all, it is a tonic, and occasionally eating it will not have any adverse effects.
