Under Australian rules, for a drug to get regulatory approval, you have to be able to identify the active component. A lot of traditional Chinese medicines are demonstrably efficacious, but either haven't had their active constituent identified, or have a number of active components that work together, making it very difficult to identify exactly what the active component(s) are.
Big pharma spends serious money on investigating many of these medicines. Maybe Chockstoners know something they don't, or maybe some of you are talking out your arses. |
