Generally speaking, TCM sees children as possessed of fragile internal organs and lacking their full allotment of blood and qi. At this stage of life, supplementation is largely aimed at facilitating digestion. During our energetic adolescent years, it's hard to over supplement. In our middle years, when our bodies go into decline and we find ourselves often tired, the focus shifts to tonics for the blood and qi.
一般來說，兒童時期，臟腑嬌嫩、氣血也不飽滿，此時「進補」以健脾胃、助消化為主；精力充沛的青年時期，則不宜過度補養；體質轉衰、經常過度疲勞的中年時期，則應補氣血；器官老化、正氣不足的老年時期，不能躁進，得少量、持之以恆的補益。
