I took EpitanMan off ignore and ended up in a childish fight. Guess I haven't grown up yet.
All of what I am about to say is subject to confirmation. There are other complementary medicines/plant extracts out there that contain notable amounts of polyprenols. Mainly Chinese ones. Pine needles are not the only nor richest source of them. Ropren is, as far as I know, the product with the highest concentration of polyprenols, but I can't state that for a fact.
I will confirm this info later, when I have dug it up again.
Cheers Bill
