Does the ma Huang in diet pills even work?

Yes, but it is dangerous. Do not use it.

Update: Pure Ma Huang Pills works a lot better then diet pills that have Ma Huang in them. Pure Ma Huang can really suppress your appetite which it can be good but have a high protein diet to suppress that stomach ache that comes a long with it. I eat a heavy protein diet including this pure Ma Huang pill. I seen major weight loss from it. After awhile I just take the pill and continue to eat a good protein or weight loss food diet.
