Treat all injuries caused by metal blades or arrowheads, as well as contusions and sprains, even cases of death-like state from dog bites. Immediately apply the following powder to the wound. The blood will transform into yellow fluid; applying the powder again will revive the patient without pain. In cases of internal injury where blood enters the zang-fu organs, decoct child's urine (Tongbian), add a small amount of wine, heat it, and mix with one qian (approx. 3-5g) of the powder. Take orally for immediate effect. For livestock injured by horn thrusts where intestines protrude but are not damaged, immediately reduce them into the body, suture the wound using mulberry bark thread, apply the powder to stop bleeding and revive instantly. For postpartum women suffering from fainting due to retained lochia, malignant blood rushing to the heart, dead fetus in the womb, or death due to retained placenta, provided the heart region remains warm, immediately take one qian of the powder mixed with child's urine. This will expel foul matter resembling pig liver, preventing wind-blood and blood-qi disorders for life. If blood above the diaphragm transforms into yellow fluid, it can be vomited out or discharged via urination, which is very effective.
