In response to the above. NO !!!
DO NOT TREAT BURNS WITH ZHENG GU SHUI !
Zheng gu shui is a muscle relaxant. It burns the skin. On any kind of open wound, it will burn like hell!
REPEAT: ON ANY KIND OF OPEN WOUND, IT WILL BURN LIKE HELL !!!!!
To soothe burns, use ointment, first aid cream, face cream, petroleum jelly, even cold water, etc.
Chinese grandmas used to use soy sauce to soothe a burn.
Two Chinese folk remedies for burn wounds are to apply olive oil, sesame oil, or to apply talcum powder on the burn wounds.
For scrape wounds, crotch wetness and itch, water chestnut flour, baby powder, talc, all work equally well in drying out wounds and wetness. However, regular flour of wheat becomes wet when applied and do not serve to dry out wounds. Conceivably, in an emergency, wheat flour used for baking could serve to soothe a burn wound.
