Immediately mix mustard seed powder with water to fill the umbilicus, then apply heat through a cloth layer using a hot object. Recovery occurs upon sweating.

Burning *Atractylodis Rhizoma* (Cangzhu) and red dates frequently can prevent epidemics. Alternatively, place the inner garment of a person in the early stage of illness into a steamer and steam it for the time it takes to burn one incense stick; the whole family will remain uninfected. Or, frequently bathe with decoction made from peach branches growing towards the east to avoid infection. Alternatively, finely chop pine needles and take them warm with yellow wine, three times daily. Additionally, burn red dates, *Artemisiae Scopariae Herba* (Yinchen), and *Rhei Radix et Rhizoma* (Dahuang) in the room every morning. Or, take one jin each of *Atractylodis Rhizoma* and red dates, pound into a paste, and form pills the size of marbles; burn one or two pills daily. Or, soak one large *Cyathulae Radix* (Guanzhong) in a water vat and add a small amount of alum. Or, bake *Plantaginis Semen* (Cheqianzi) between papers, grind into powder, and take two qian mixed with water. Or, throw a pinch of black soybeans into the water vat every morning so the whole family remains uninfected. At the fifth watch (early morning), secretly drop a large handful of black soybeans into the well without being seen; families drinking this water will not be infected.

Additionally, slice raw *Rhei Radix et Rhizoma*, place in a container, seal with paper, and steam it inside the rice pot when cooking meals.

Grind realgar (*Realgar*) and *Atractylodis Rhizoma* together into fine powder. Mix with sesame oil and apply to the nostrils.
