Mangosteen peel (mesocarp) for viral infections on young children

My daughter started to get some warts on one of her fingers. Applied crushed mangosteen peel without pericarp (removed hard outer layer). Within 1 day she was healed. She said there was a tingling which is a good indicator that the mangosteen (and whatever active ingredients) is getting under the skin.

I have noticed that this treatment is not as effective (but still effective) for adults and think it is due to our thicker skin.

Children appear to be healed.
