Logonberry, yes the forum is such a comfort to me too.
I buy from.Morrisons, large tub for ?5. Coconut cooking oil. Purely coconut.
It's in the European isle with the Polish food etc. Best value I have found.
Honestly, when my IBS gives me diarohea, I am in pain. But after I have wiped with the oil on a cotton wool pad after using tissue I am in no.pain whatsoever. So if the oil prevents that pain it must be powerful.
And that vag dryness I had was torture. But the oil sorted that out.
Try it, I really hope it helps you. Also if you use It to wash with, well what I mean is put it on before you shower in the affected area. Seems to protect the skin.
