There is a working list of cure claims on the wiki, under "Success Stories." I haven't had time to find a source for them all. The only other potentially antibacterial cure claim is for grapefruit seed extract spray, which is touted in another forum.
I would add urea and allantoin as potential antibacterial keratolytic agents (keratolytic= soften and break down the outer layer of skin) that have not been experimented with very much. Coincidentally, fly larvae produce both of these.
Looking up maggot debridement therapy :P I came across this sentence about hyperkeratosis:
"In pathologic desquamation [skin shedding], the stratum corneum becomes thicker (hyperkeratosis), imparting a "dry" or scaly appearance to the skin, and instead of detaching as single cells, corneocytes [biologically dead cells] are shed in clusters, forming visible scales."
So something is binding these dead cells together, right? What could it be?
