Linden,
Yes, like NSSG said,all those are for getting rid of candida/yeast issues. Ad BTW, be careful using those as they can cause a rebound effect and actually make you much worse initially.
A few on this forum have reported using these and found it put them into a flare or excarcebarted their symptoms. If you do decide to go ahead with them, use only ONE at a time, and do it slowly.
There are lots of other factors you could tinker with and try as well:
Diet modification, supplements, probiotics, etc.... Fr a whole listing, you can check out the link in my sig.
Good luck, and I hope it works for you.
