Thanks for the warning about it spreading, I'll sink a container & put in there. I dont think, if it works (and I've heard it does) that my daughter will worry about the taste/smell. She suffers with awful migraines sometimes despite being on daily medication for them. If taking half a dozen stinky leaves does the trick I know which I'd do. As for the arthritis, my mum used to take f/few tablets from a health shop. I'm not sure whether it is a pain reliever or a preventative or what but I already have arthritis in a couple of joints so I figure it's worth a go. My mum has given up alsorts of foods which are supposed to be bad; tomatoes, rhubarb etc but I thought I'm giving the stinky stuff a go first before such drastic measures!
