Mantequilla for burns 1
What is up with everyone's abuela always saying to put butter on burns? I was always skeptical of this one even when I was a kid. Putting butter on a burn can actually set you up for an infection, so don't do it ... EVER! Save it for your toast, por please.
Mayonnaise for lice 2
Rubbing mayonnaise on piojos will suffocate some, but it won't kill the eggs. Plus guacala!
Toothpaste for acne 3
I totally did this as a teenager. Once I put toothpaste all over my face and fell asleep. When I woke up, my whole face was swollen because toothpaste has ingredients in it that can actually irritate your skin. So then I had pimples and a swollen face, but at least I smelled fresh.
Petroleum jelly as lube 5
Mamas, you should only ever be using water based lubes. Petroleum jelly in your hooha sets you up for a bacterial infection and that's not sexy.
Coffee for hangovers 6
I love coffee, LOVE IT, but the reason it's not good for you when you have a hangover is that too much alcohol the night before leaves you dehydrated. Too much coffee the next morning is going to further dehydrate you. So sip on a tiny bit of coffee if you must, but chug on water.
Garlic for yeast infections 7
Some people say that if you have a yeast infection and you put a clove of garlic in your vagina it will help the infection go away, but putting a piece of garlic up in there might actually make your infection worse. And what if it gets stuck in there? Then you have to go to the doctor and say, "I have a yeast infection and I think I may have lost a piece of garlic up in there too."
