Tannic Acid to Harden Blisters and Calluses
Tannic Acid Natural History and Blister Care
Hikers and rowers share a common affliction, namely blisters. As a rower on an 8 person crew I have to contend with blisters all the time. They can form while using rowing machines or while using oars on the water (it's a mark of pride to compare cheese-grater like hands). Hikers often get blisters on their feet from ill fitting shoes and socks (first thing to do is make sure you never we new hiking shoes long distances and get good socks, yes, pay $15 for a good pair of wicking socks). I've had people complain of blisters from riding horses, high heels, and more. One of the solutions I use, which I want to share with you, is the use of natural plant tannins or tanic acid.
