The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases) states: When a disease has just healed, Qi and Blood are still deficient, and Body Fluids have not yet recovered. Engaging in labor immediately causes relapse. If speaking or thinking excessively, it leads to...
The *Yimen Fang* (Prescriptions from the Medical Gate) states: It is discussed that: For one hundred days after the initial recovery from warm diseases or severe illnesses, consumption of pork, intestines, blood products, fatty fish, and greasy foods is prohibited. Also avoid chestnuts, various fruits, and hard-to-digest solid foods. The Stomach Qi is still cold and weak, unable to tolerate diarrhea. Without purgation, death is inevitable; with purgation, survival is possible. Caution is essential.
After the initial recovery from illness, only congee should be eaten. It is better to eat little and remain slightly hungry than to overeat. Do not eat arbitrarily. Even if craving food, do not provide it. As time passes, gradually introducing meat such as muntjac, deer, pheasant, and rabbit is advisable.
To treat relapse caused by rising early and overeating after heat diseases have just healed:
Gardeniae Fructus (10 pieces), two sheng of water, decoct to obtain one sheng, remove dregs, and take in one dose. Keep warm to induce slight sweating, which is ideal. This clears all types of relapse.
Another prescription: Burn Tortoise Carapace and Plastron, grind into powder, take one fangcun bi (square-inch spoonful). (Same as in *Ge Shi Fang*.)
The *Ge Shi Fang* treats relapse due to premature labor and improper diet after severe illness has just begun, causing exhaustion and a desire to die:
Take a small amount of Hufen (Lead Carbonate) with water.
Another prescription: Burn rice baskets, grind into powder, take one fangcun bi.
The *Duanju Fang* (Short Drama Prescriptions) treats relapse due to dietary labor:
Puerariae Radix (five liang), decocted in five sheng of water to obtain two sheng. Cool and divide into three doses.
The *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) treats relapse due to dietary labor:
Semen Armeniacae Amarum (five pieces), vinegar (two sheng), decoct to obtain one sheng, take to induce sweating.
Another prescription: Burn human feces to ash, take one fangcun bi with water.
