Com on, brainwashed. If Big Medicine spent as much time finding natural cures as they do on Big Pharma stuff, vaccines would never have been developed.
Wtf do you actually understand that a huge amount of medicaments are "natural"...
What are you even talking about? Of course they are natural. Everything in the universe is natural. So far, nobody has even figured out how to think extra-universally.
So, what is the difference? The difference is that medicine is simply a small part of a thing that is natural. For example. Vitamin C is an extract or "made" substance that is natural. It might be a poison, but because of the kind of substance it is, it is so extremely non-toxic, even in rather large doses, that it is essentially harmless.
Other extracts from nature might not be so non-toxic. And that is part of where the medical goes nuts with what they are doing. They extract normally not-toxic substances from plants or animals. These substances are normally non-toxic because of their place in nature, where they are balanced by other substances to be non-toxic. Once out of their natural environment, they become toxic when "fed" to people.
If medicine stopped there, it might be border-line okay. But it is when they chemically make substance that are generally not found in nature, and feed those to people, they become dangerous.
Use nature as it was meant to be used. Leave the substances in their natural form. To get vitamin C, eat the orange or cherry, so that you get the whole benefit, and also the natural protection from any potential toxicity.
