In my humble retired-nurse opinion, it can be a tricky business. Herbs, though "Organic" still are made up of chemicals which can adversely effect such things as kidney and liver function. And can work against some prescribed medications. A healthy person can probably ward off most ill effects of herbal concoctions, but in an elderly or unhealthy person it might be thought of as Russian Roulette. Just my 2 cents.
as a person who more and less suffers with side effects of any given pharmaceutical medicines..they are not very safe neither
Even if the doctor prescribes something, I normally bottle out of trying it as I am too scared of the side effects.
Try him with any old herb tea GF, and see if there is any difference.
