I don't see what's wrong with merely presenting information. No one is recommending anything to anyone. I for one am glad to have every and all possibilities brought to my attention, as who knows what might eventually prove to be effective. We can all make our own decisions about what we want or don't want to try. Better to know than not know, imho.
And that noscapine research is something that I probably wouldn't have found on my own, so I'm glad to know about it.
I can think of a lot worse things to take than a non-addictive opium derivative that not only appears to be remarkably safe, but also is anti-cancer and anti-stroke, including some of those nasty HIV and other antiviral drugs that completely trash the liver and some of them probably the kidneys, too!
But you're right abstractblue - we also have to be careful. But discussing things is one way to find out if it's something rational to take, what the cost/benefit might be, etc. If no one posted suggestions like that to discuss, we might actually make worse choices. imo!
