Wiki is wrong =-)
Wiki should say
"It has also been shown that hydrogen peroxide, ..snip.., can slow wound healing if used chronically"
I use it on my patients involved in car accidents/major trauma constantly, is a wonderful disinfectant, and as Ponder said, it does cauterize the wound a bit. Just use a 3% solution and dilute it by half.
For future reference for large scrapes that wont stop bleeding
-Mild: wash, parrafin gauze->gauze->bandage open after 1 day
- Moderate: Wash, parrafin gauze->gauze->bandage; Elevate and direct pressure for 15minutes. Cold compress on top of area. Open after 2hours, if still bleeding ->doc
-Severe /squirting bleeding that "pumps" -> doc
