• Medicinal plants operate through synergistic action that cannot be understood by isolating and studying their chemical constituents.
Unsubstantiated claims. Illogical too. There is no real support for tis synergistic action, and just as much for antagonistic action. Secondly If they cannot be understood then how is this person making such a claim unless he has studied all medicinal plants and compared them to all the action of their individual isolates.
Here is a guy who I believe supports the idea of synergistic action. Read up on the link. It is just to good.
