Hoodia for weight loss

My friend asked me for my opinion if taking Hoodia would be a good idea or not. She says she wants to lose weight fast but finds it difficult as she loves to eat. She watched a program on tv in which they recommended Hoodia, type of Kalahari cactus that's known to help suppress appetite. Oh yes, i've heard of Hoodia before. Many of my girlfriends take that to stay slim. They never told me where they bought theirs from but i know they got it from some tv program too. If she wants to try Hoodia, then by all means. I now how hard it is for fat ladies to find clothes that fit and she will be happy to shad a few kilos.
