Don't take this as me being argumentative, I'm not trying to be! But it's a common misconception that nature can only offer so much and then man's medicines have to step in. Man's medicines are often synthetic versions of the healing properties found in plants, and often aren't as effective. The reason synthetic versions are created isn't because they're safer - on the contrary, they usually have very dangerous side effects as we see on the information leaflets - it's so the medicines can be patented and therefore are profitable. If they could patent medicinal plants to sell then they wouldn't bother making a synthetic equivalent. Healthcare in its broadest sense isn't about healing, it's about making money. Take cannabis for example... the most medicinal plant on the planet with no harmful side effects, no deaths ever, which can cure multitudes of diseases from epilepsy to cancer, and yet the public are warned that it's a 'dangerous drug'. Same for the medicinal properties of magic mushrooms, which are excellent for treating neurological illness, amongst other things. Nature gives us so much and yet in our arrogance we often choose man's creations over nature's provisions... coconut oil, ginger, hawthorn, nettles, garlic, onions, herbs, dandelions, cocoa, honey, aloe vera, wheatgrass, tea tree, catnip, alfalfa, etc etc etc... All of these things are examples of powerful healing plants. If taken in correct amounts there's no need for soooo many of the prescription or over-the-counter drugs we're reliant on, and we'd see a massive increase in healing, and a massive decrease in illness. It's a fact there's a LOT less chance of being harmed by natural medicines than by synthetic ones. (And by natural medicines I mean the raw medicinal ingredients, not the so-called 'natural medicines' you can buy in shops, which I don't trust at all). This is a very interesting subject, I hope you don't mind my long reply!
