9. Don’t Look for Water in a Cactus
You know not to drink your urine while lost in the desert, but surely a cactus is a good source of water, right? WRONG again!
Unless you know with 100 percent certainty that the cactus you have stumbled upon is the non-toxic fishhook barrel species, you will put your life in serious risk by drinking from a cactus.
Even if you’re positive a cactus is non-toxic, the moisture inside is far from drinkable. It’s a gooey, pulpy mess that tastes so bitter that you likely couldn’t eat/drink it.
The so-called water inside these desert plants is actually a very noxious substance. More often than not, drinking it will cause vomiting and stomach pain.
It is also likely to lead to heat stroke and, once again, you’ll be really fortunate if you recover from that after lying on the hot desert ground for a while without any shade.
