“LL-37 is proven to heal wounds in people.”

Not established

The reviewed evidence does not establish this statement. This does not prove it can never be true.

The first 34-person leg-ulcer study reported possible benefit. A later study assigned 149 people to LL-37 or placebo. Of those people, 148 received a study treatment. It found no clear benefit for the full group. A 25-person diabetic-foot-ulcer study found a limited sign of new tissue growth, but no clear changes in other measures. These results do not prove general wound healing.
