I have a question I hope the good people on this forum can answer:
I have read a lot about the merits of Coconut Oil on this forum and some other places. The thing is I am on Nitro that has been prescribed by my doc. I don't want to upset her by abandoning her treatment but am keen to try the Coconut Oil. Has anybody tried using both together, or has anybody just switched and found it made an imrovement?

If you want to try coconut oil there is no reason you need to drop the nitro. Just space them far apart from one another in terms of application so that the effect of nitro. isn't diluted. Coconut oil didn't work for me topically. It actually caused me a lot of irritation. But I do include it in my diet for its health benefits. And there are, as you mention, people on the board here who have had good success with it. Can't hurt to try it, but it doesn't have to be an either or with the nitro.
You can just use them both.
