What are natural ways for treating 'sweaty hands'?

OTC roll on: deodorant. There are also excellent mediciations and if severe botox has been shown to be helpful- get examined.

None: Try an antiperspirant. If this is not satisfactory, see a dermatologist. "Natural" does not indicate that any product is safe or effective: it is a meaningless term meant to swindle you. Poison ivy, lead and carbon monoxide are all examples of natural substances.
