Pain in the heart region in infants and young children does not originate from the Heart itself, but rather from pathogenic factors invading the vessels governed by the Heart. The Shaoyin (Lesser Yin) channel belongs to the Heart, which serves as the master of the five zang organs and six fu organs.
If injured by cold pathogens, cold evil clashes with the meridians and collaterals, thereby causing pain in the heart region.
To treat pain in the heart region in infants and young children, if one observes that the child uses their hands to rub the chest and abdomen frequently and cries even after rubbing, this indicates unbearable pain in the heart region. It is appropriate to administer Shaoyao San (Peony Powder).
Chi Shaoyao (Radix Paeoniae Rubra), Renshen (Radix Ginseng, remove the radix tip), Baizhu (Rhizoma Atractylodis Macrocephalae), Huangqin (Radix Scutellariae), Chuan Dahuang (Radix et Rhizoma Rhei, crushed and lightly stir-fried) (each 1 fen).
Grind the above-mentioned herbs into a coarse powder. Administer 1 qian per dose. Add one small cup of water,
boil until reduced to 0.5 cup. Strain the decoction. Administer at any time, adjusting the dosage according to the child's age and size, and serve warm.

Grind the above-mentioned herbs into a coarse powder. Administer 1 qian per dose. Add one small cup of water,
boil until reduced to 0.5 cup. Strain the decoction. Administer frequently while slightly warm, adjusting the dosage according to the child's age and size based on clinical judgment.

boil until reduced to 0.5 cup. Strain the decoction. Serve warm at any time, adjusting the dosage according to the child's age and size based on clinical judgment.
For treating pain in the heart region in infants and young children with intermittent thirst, use Peng'ezhu San (Curcuma Zedoaria Powder).
Peng'ezhu (Rhizoma Curcumae Zedoariae), Renshen (Radix Ginseng, remove the radix tip), Guixin (Cortex Cinnamomi), Huangqin (Radix Scutellariae), Sheng Gan Dihuang (Radix Rehmanniae Recens, dried), Muxiang (Radix Aucklandiae), Gancao (Radix Glycyrrhizae, stir-baked until slightly red and crushed, each 1 fen).
