Raw apple cider vinegar? I love the stuff! (for the effect it has on my health, not for the taste, *shudder*). I can sniff even a few drops out in my drink, so instead of trying to make a yummy drink I just mix one tablespoon of vinegar with two tablespoons of water, add a few drops of stevia to make it more bearable, and shoot it down followed by a big gulp of water or juice.
My mom also soaks a cotton ball and tapes it to the place overnight to get rid of planter's warts.
I've heard it's really good for skin care as well. I've tried brushing some on my face with a cotton ball after cleansing, or adding some to a sugar scrub or lotion. I didn't notice any amazing results with that, but nor did anything bad seem to happen.
I've also used it instead of conditioner in my hair, which worked really well but my hair is so thick that it took too much time! It didn't seem to be doing any better than natural conditioners, (which are quicker), so I just quit.
