I've tried coconut oil for many things including dry mouth and oral health, it works great if you can get past the taste, not that it tastes bad, but it is oil. I've also replaced my cooking oils with coconut oil for the health benefits. A lot of people think it's unhealthy because it's solid, but it surprisingly melts with body heat. I use it to see if it's too hot or too cold in my house. Coincidentally, the very degree it melts at is perfect house temperature for me.
Oils (in small amounts) are very important for the body. They don't call them essential oils for nothing. It's not enough to just drink water, cause what does that do? It rinses things away. In order to keep moisture in your body so that your organs can stay wet and function, you need oil to keep that moisture. This is why Gatorade helps keep athletes hydrated, it has a small amount of oil in it. What an unhealthy way to get it, in kook aid chemicals. I just add a scoop of coconut oil about the size of a blueberry into something I eat everyday. Fish and nuts do the same, the oil in walnuts is especially good for brain function.
Coconut oil is a cure-all! I use it as lotion on any body part, and unlike lotion, it heals scraps and bruises and is a natural germicide. I even use it in my hair (sparingly and diluted with warm water). It works as a Chapstick. Some people rub a little between their fingers then lightly pull on their eye lashes to help them grow longer. Basically it works on your entire body inside and out. But don't eat it by the spoonfuls like a former miss America did. Use it sparingly and don't take it to an extreme, a little goes a really long way.
FYI: Coconut oil makes the best popcorn- that's what movie theaters use to make their popcorn.
