I can understand your stance and where you are coming from on why you or any supplement maker comment in this matter....
Consider this a rant against the healthcare system:
Probably 5% of doctors will know what cissus is when you mention it. The vast majority of doctors, even those who know what it is, will knock it simply because of it's mode of sale (i.e. a "supplement"). The ones who have no clue what it is MIGHT take a minute to look it up, and will of course zoom in on the 1 potential side effect that was identified by 1 doctor in Rome.
