Well, i understood what An-D was trying to say, a more natural, nature based chemical compound vs a human made synthetic compound. Sure, there are plenty of toxins in nature but most of these are in relation to and concentrated with animal or plant defense mechanisms, and i don't know about you but i'm not in the habit of smearing cobra venom all over my clothes anyways...
And i certainly would prefer smearing something like beeswax on my skin rather than something like Grangers no matter how safe and non toxic the companies that make this stuff tell me it is.
Human made synthesized chemicals or nature distilled isolations and concentrations on the other hand, whole long list of toxicity in many different areas and applications. I'm not saying i don't use the latter, course i do, but i think limiting exposure is also a good idea too.
