Hey there traveller... just wanted to second what you have have said about "natural" not necessarily being 'safer' or 'better'...

I say to the (adult) students I teach every every year that synthetic medicine is mostly based on the qualities/ingredients found in nature...

Some of our best healers, and best poisons are found in plants, and people have found it expedient to reproduce them in laboratories.

Remember when you are talking with a doctor and she (or he) asks about medication , tell them about vitimins, supplements, and herbal medicines you take... as they can interfere or alter the way that prescribed/synthetic medicine works - and vice versa...
