[QUOTE=Brazilwood] One point I would emphasize though...in my spiritual belief, I think God's creations are perfect and he gave us a solution for every need. Whether the solution is found in plant life or our own faith, every sickness has a cure. Many are healed with placebo's. So, the power of the mind itself can heal and work miracles. Doctors nor Scientists have an answer for that.[/quote]
I am more of a skeptic than you are, that much is certain, but that doesn't mean anything about 'smarts'. It is a field I've been studying for a few years, though.
The placebo effect is undoubtedly real, and the power of the body to heal itself is nothing short of amazing. Where that comes from is a matter for personal interpretation; I just see the amazing diversity and complexity of nature, of biology, of psychology blending together.
[quote] I understand your point Mattia about isolating the active ingredients to make them more standardized in potency. As you pointed out..even wood properties differ within the same species depending on their origin. Brazilian Rosewood from Bahia is VERY different from Brazilian Rosewood from Santos due to soil conditions, amount of rainfall, sunlight, elevation..etc. So, the same would go for medicinal properties in plants. The variation in strengths would definitely be different from one region to another. To standardize this would just make good sense.[/quote]
Indeed. Standardizing growing conditions might help, but plants will remain variable. And there's a real problem with variability when it comes to amounts of (highly) active natural ingredients vis: toxicity, which I'll address below.
[quote] One point you made though Mattia I would choose to question is eliminate the toxicity of some of the plants. Doctors and Scientists really understand so little (though they might believe otherwise), I think it's highly possible the toxicities of the plants can actually be the cure. The toxic contents of the plant may be what actually kills the virus or gene that causes the illness. Chemotherapy is an excellent example. Who would think that something so invasive to the body, and makes a person so sick, that it could have any positive results. We really have lots to learn when it comes to medicine. I believe many plants hold the key...we just haven't done the necessary testing to gain enough knowledge. I'm just thankful there are those far more intelligent than myself to sort through it all. I don't depend on my intelligence, I depend on my faith in God to walk me through another day.

Couple of things: very few (let's almost say 'no') effective antivirals have been found anywhere, ever. There are drugs that slow or limit viral spread, but to date, nothing much that can actually get rid of a virus, particularly retroviruses which enocde themselves into DNA. I also can't foresee any medical means (ie, natural plant extracts) to undo genetic ailments, purely because of the complexity associated with genetically carried diseases/ailments. Even gene therapy remains, for now, largely a pipe dream when it comes down to most syndromes/diseases. If we're talking genetic conditions that symptomatic approaches can't heal, medical technology, if anything, is most likely to provide answers.
Also, Scientists and Doctors (the good ones, anyway) are painfully, fully aware of the limits of their knowledge. They are, however, perfectly lousy at communicating with the public, as a rule, and mainstream science reporting (newspapers, TV, etc.) is so rife with innacuracies that I cringe almost every time I read/watch science reporting in mainstream media.
The awareness of the limits of knoweldge is where the drive to discover more, the experimentation, the fundamental and applied research comes in. We use a lot of drugs that we don't know the working mechanisms for. We know they work better than placebos and we do the best we can to ensure they don't have (too many) undesired side-effects, but we don't really know why or how they work. Paracetamol is an example of a drug that's been used for many, many years, but whose mechanism of action is anything but fully understood. The reason scientists want to elucidate the mechanism of action is that it provides insight into how a certain substance does something, both positive (desired effect) and negative (undesired side-effect), which could lead to more efficiently targeted drugs that can be used at higher (more effective) doses without the nasty side effects.
Re: toxicity, it's well known that a number of toxic elements can have beneficial effects, so I don't worry about that in terms of medical research. In fact, pretty much every drug in use is toxic to some degree; after all, you're messing about with the body's delicately balanced internal systems. One of the key stages in any pharmacological research is investigating its pharmacokinetics (how it distrubutes in the body) and pharmacodynamics (how it works, and how toxic it is). There has to be a balance between the toxic effects (undesriable) of a substance and the desirable effects. Chemo is a textbook example of an extremely toxic treatment; that level of toxicity is only acceptable because of the effect it can have, and the seriousness of the disease it is designed to treat. I wouldn't worry too much that things get thrown out purely because of toxicity, because if they're found to have some effect, even with HUGE side effects, the race is on to isolate that positive effect the substance has from the negative without (if possible) affecting its potency.
