According to *Nashii Bingyuan* (Chao Yuanfang's Treatise on the Causes and Manifestations of All Diseases), regarding the condition of "Red Wandering Swelling" in children: If a child has weak muscles, wind-toxic heat qi will invade due to deficiency. The heat-toxin contends with blood and qi, causing the skin to turn red and swell. This wind follows the movement of qi and wanders without fixed location, hence it is named "Red Wandering Swelling".
*Benshao* records treatments for children suffering from red and white wandering swelling.
Use shrimp, crushed and applied as a poultice. (Shrimp without whiskers or those that turn white when boiled should not be eaten; those living in paddy fields and ditches have slight toxicity, and internal use carries significant toxicity.)

The resulting frost forms like pearls; scrape off the medicinal powder. For cases involving irritability and thirst, refer to the subsequent formula for relief.
