Perlite is puffed up volcanic glass that is added to soil to provide extra aeration. Perlite is porous and allow water to drain well so it's a perfect addition to plants that require well-draining soil like cacti or succulents. 

You can easily modify potting mix to better suit individual plants by adding perlite to potting mix.
