This natural clay does EVERYTHING.
When I just started to use natural deodorant, and smelled horribly, I did an 'armpit detox', using bentonite clay, apple cider vinegar and tea tree. It worked really well and definitely made me smell less bad. Still, the natural deodorants I used weren't that fantastic, but now I've found one that does work for me, guess what ingredient is in there that the others didn't?
You guessed it - Bentonite Clay.
Bentonite clay is a natural clay formed from volcanic ash, containing many minerals such as calcium, magnesium, and iron. Bentonite clay comes from Wyoming, USA. A very similar European version is called Montmorillonite, which comes from France.
When mixed with water (or apple cider vinegar in my case), it forms a clay. Do to its adsorbing qualities, you can use the paste to remove impurities on your skin, such as excessive oils and dirt. It can help with acne as well. You can also ingest bentonite clay (1 teaspoon per day, dissolve in water) to remove toxins from your body, although it hasn't officially been proven to help. It can treat constipation and remove diarrhea when ingested.
It also does work wonders for rashes, such as a rash from poison ivy, or diaper rashes.
There are even more things bentonite clay can do, such as remove lead (from water supplies for example), lower your cholesterol and is one of the ingredients in cat litter to absorb liquids and keep the litter from smelling to bad. Apparently Bentonite Clay can also help with weight loss, but I don't recommend losing weight by taking only bentonite supplements, it's a lot healthier to loose weight when you eat less calories and do more exercise.
