I'm a little concerned about the availability and use of unlicensed "chinese" medicines.
Not because they don't work, as invariably, idoctrinate enough of the stuff with viagra, prednisolone etc, and you will get the desired effect you're after.
At a cost.
I pump poisons into people for a living, wherever I can, I try not to.
- but at least the crap I use has been tested to some degree.
(And yes I know, the westernised sh1t isn't perfect.)
