Alum is a natural stone with many possible uses in the home.

You can buy alum stone in pharmacies or health food stores in its “natural” or “synthetic” versions. Of course, we recommend you buy the natural or alunite version, whose main component is Potassium-Alum or K Al3 (OH) 6 (SO4) 2.

This volcanic stone comes from magma rock. As it’s a natural product whose origin depends on the alterations of potassium feldspar in the rocks, you’ll probably notice differences in color and texture between one stone and another. Don’t worry, that’s totally normal.

Let’s take a look at how you can use this stone in your house.

1. Alum as deodorant

The most common use of alum stone is deodorant. In fact, you can read thousands of stories on the internet of people who have abandoned conventional deodorants for this natural option.

Many of these people have decided to make a change in the search for an aluminum-free option since some studies have associated the use of deodorants with aluminum to breast cancer. Some researchers have suggested that, like estrogen, which can promote the growth of cancer cells, aluminum-based products may contribute to the development of cancer. However, there is still no conclusive data in this regard.

It’s worth noting that the use of this stone doesn’t mean abandoning aluminum since this stone is a saline compound based on aluminum and potassium. So if that was your only reason for the change, you should rethink it.

It’s true that when using this stone as a deodorant you avoid alcohols, parabens, and other preservatives. Alum is totally natural and has bactericidal and antiperspirant effects. To use it, you just have to moisten the stone and rub it over your armpits, as you would with a roll-on deodorant.

Note: Be aware that alum ore may cause allergies. Stop using it if you experience a rash or discomfort.

2. Acne treatment
