It sounds like an allergic reaction to aluminum chlorohydrate, it has been said to be very toxic. There have been numerous studies done that have found a link between more traditional deodorants and breast cancer. With that said, I have tried most of the natural deodorants on the market and the only two that actually work are: Kiss MY Face make sure it is the "Active Life" kind or it won't work as well. (The cucumber and green tea is my favorite). The other one that works great is Natures Gate "Autumn Breeze" is my favorite scent. All the other brands mentioned work so long as you are in a nice air conditioned room. By try jogging for an hour, or gardening/cleaning out the chicken coop on a warm spring day and you can forget it you might as well not wear anything, at least for me anyway ha ha. You can buy these from Amazon.com if you don't have a local retailer/health food store. Hope that helps.
