Benefits
Before an infant develops smallpox, fetal toxins remain in the internal organs and may erupt due to seasonal epidemics, potentially resulting in black, sunken, or inverted lesions.
Instructions for Use
At that time, mix the powder with pig’s heart blood or rabbit’s blood until smooth, then dissolve it in hot wine and take it while warm. In spring and autumn, take 1 pill per dose at 2 fen strength to gradually dispel the smallpox toxin, resulting in a sparse eruption; if an epidemic of smallpox occurs and the body develops a fever, immediately grind and take 1 pill, and the toxin will be expelled through the stool; if black, sunken, or inverted lesions appear, take 1 pill, and it will revive the dying.
Note
If taken after the seventh day of the smallpox eruption, it may deplete vital energy.
