Although using antiperspirants will not counteract the healing effects of homeopathic treatment it is generally unwise to stop your body from sweating. Suppressing your sweat (whether it is under your arms or on your feet) can cause other problems, as sweating is one of your body’s natural ways to eliminate ‘toxins’.
A deodorant is a safer alternative as it won’t prevent your body from sweating, but it will stop the bad smells!
