Cacti contain significant stores of water that can be used as an emergency source in the desert. You cannot drink water from a cactus because it is toxic and will make you sick. If you are lost in the desert or abandon, your best chance is to hunker down in the shade somewhere and hope for the best. It's complete t v media myth that, yoi just get the water from the cactus. The last thing you want to do is to eat the inside of a cactus, no matter how juicy it may seem to you - it has alkali poison in it.
