On health savings accounts

As an investment writer, I haven't checked out a health savings account much. But it certainly sounds like a good idea. I want to check out what you're allowed to spend the money on, however. If you're not allowed to spend it on vitamins and alternative therapies, then it could be a waste of money. I am afraid of having an accident and wracking up large medical bills in an emergency room, but I'm more afraid of having cancer or something else horrible like that and being told my insurance will only cover the treatments that will poison me and probably won't even work. I think conventional cancer treatment is a huge scam for the most part. I think my real health insurance is the vitamins, minerals, supplements and fish oil capsules I take.
