I have been wanting to try OP with castor oil. I am put off by the taste and the fact that actually did use it 16 years ago to induce labour with my second child. It was not a pleasant experience and even 16 years on the smell of castor oil brings back unpleasant memories.
But I would really like to try OP with it. I am thinking of maybe adding a little peppermint oil to it, to make the experience a bit more pleasant. And it's so darn thick, how does that work out?
