You can generally find this coming as a crystallized stick, and this is one of the most natural deodorants that you can find. It is inexpensive and has a shelf life of about a year so you can be certain that you will be getting value for money.
Hyperhidrosis - How to make Herbal tea deodorant? These are the recipes...
Make a tea utilizing such antibacterial herbs as peppermint, sage, or coriander. When it is cool, dilute it with mineral water, add a few drops of your favorite essential oil, and apply on your underarms, and other sweat prone areas for cooling freshness.
The herbs I've listed below are good either by themselves or mixed with the other herbs I've mentioned. You will notice that I have only given you a small list of herbs to choose from and that's because the herbs to actually reduce sweating are not as numerous as those that can induce sweating!
It should also be noted that I haven't given you any specific directions on what to do with any of the herbs, except in the “Herbal teas” section, for the very simple reason that I am not a qualified herbalist.
