Yes Fonty, if people just ate lots more fruit and veg, they wouldn't need drugs. I was reading there are so many substances in them, some discovered, some undiscovered, and isolating a substance and making a vit pill isn't the same. I expect they work in synergy.
Elderberries have a substance that stops viruses attaching, and they have made a tincture called sambucol to take for flus etc. But it is so expensive for tiny bottle. They say take so many spoonfuls daily for winter protection for immune system. It would cost the family a fortune.
Another way of fleecing the public.
I was wondering if collecting elderberries and making your own cordial would work the same way.
