I had food poisoning once, it was terrible, some of the worst pain I've ever felt. I literally felt like I was going to die. Vomiting and crapping out the same thick black fluid, huge painful knots in my stomach. Managed to find a tiny amount of herb (had thought I'd run out, but there was a little bit left), smoked it, and instantly calmed down the nausea to the point where I was at least able to stand up, walk down the street and hail a taxi to take me to the nearest clinic. So can definitely testify to that particular aspect of herb. Several wombmen I know also say it helps with period pains, but obviously I have no direct experience of that.
