Die Da Yao Jing was used all over Indo when I spent significant time surfing and diving there in the late 90's. It was the go to treatment by both surfers and divers for every cut, scrape and wound to keep you in the water and seemed to work from minor wounds to quite nasty back lacerations where surfers had been dragged over a reef or held down on one in some of the pumping surf.
I did get told it was illegal in the UK and hence cannot vouch for the ingredients but was far better than just betadine
