Plant molecules' benefits can be achieved through environmental hormesis without side effects.

“the problem with molecular hormesis is that those molecules which are often from plants canonically have other side effects in the human body just like Pharmaceuticals if you go to a pharmacy and you get any drug at a pharmacy that drug is going to come with a package insert of side effects nobody thinks about the side effects associated with plant molecules we're only sold a bill of goods these molecules are entirely good for us but they're molecules they're exogenous molecules they can have effects in human physiology but they're also going to have unintended side effects this is the package insert for plant molecules so in my work I have argued that the benefits do not out away the risks in many cases of these plant molecules they are in fact often plant defense chemicals”

“i think we find that the benefits are outweighed by the risks that the net benefit is not there that it's a negative because there are so many side effects to these plant molecules”
