I know this was posted ages ago , but was wondering if you found a solution?

I use tea tree deo, its natural and has a regular and a extra strength one. Its the thursday plantation people or what ever they are called, the ones who make the oil. The also do shampoo etc.

There is also available (probably from health shops or some chemists) some sort of deoderant made from a natural crystal?? ...i use to use it years ago, but have seen it around still. You can get it in raw rock form, or shaped into a deo stick or mixed with water in a spray pump. It does not have any added perfume nor smell of its own...

just a couple of suggestions I thought of after reading this post just now
