Can I use it in my garden?


Probably. These so-called 'deodorant stones' are often a sparingly
soluble form of potassium aluminium sulphate (the mineral alunite), so
you could use them as a source of slow-release potash or slow-release
aluminium. I've seen it suggested that alum can be used to 'blue'
hydrangeas, so crushed-up 'deodorant stones' might work just as well
(or as badly). Expensive way of doing it though.

If you look on the ingredients of many under-arm deodorants, you'll
see that they contain an aluminium salt of some sort, and 'deodorant
stones' work in the same way.

Won't make the comfrey water smell any sweeter though!
