The *Shenghui Fang* records that infants, after sweating, are injured by wind-pathogenic heat-toxins. These pathogens contend with the blood and qi, causing heat energy to evaporate outward, resulting in redness and swelling of the flesh accompanied by high fever.
To treat redness on an infant's body that spreads to the upper cheeks, beside the mouth, or under the eyes, appearing red like rouge, with the advancing skin becoming rough and peeling, gradually spreading further: this is caused by stagnant hot blood in the Heart. The treatment method involves using the sharp point of a small knife to lacerate the affected area to allow blood to exit, followed by administering Danshen San (Salvia Decoction).

Grind the above into powder. Take one qian of powder, add one small lamp of water, ten leaves of Zhuye (Bambusa Leaves), and half a qian of Zhuru (Bambusa Caulis in Sterile Condition). Decoct until five fen of liquid remains, filter out the dregs, let cool to a warm temperature, adjust dosage according to the child's age, and take at any time.
