Castor oil- alkaline or acidic?

When I first tried castor oil on my skin it produced a blister-like bubble on my arm that when mashed let out a clear fluid. When I did it again, I got another bubble and then no more. I used it under my arm and it cleared up some acne-like blemishes.

Now, I will undertake to remove a mole. I have read that moles are on the skin because of the body is pushing acid away. Anyway, what does anyone have to say about castor oil in regards to acid/alkaline issue? Tweet
