as with any thing to do with medical ... one needs to be aware of any kind of side effect.
As for ME i have always done the herbs. DH does what the dr will give him. i go to the dr and fine out what is wrong if i don't know and then go grazing. In my life time i have only taken maybe three kinds of precibed meds, and only two over the counter.
but like i said one needs to be aware of what they take where it is herb or from the dr.
