Another great book is "Guaranteed Potency Herbs Next Generation Herbal Medicine" by Daniel B. Mowrey, Ph.D. Keats Publishing, Inc. New Caanan, CT. This is a really good book, very scientific (which means, to those of you not used to reading scientific literature, that it is VERY informative but a little dry, but this is the least driest of scientific literature that i have read in a long time). It only discusses a few herbs, those which a significant amount of scientific research has been done on and which the Western Medical Science community has grudgingly begun to accept. Namely, Billberry, Butcher's broom (which i take for non-rheumatoidal arthritis), Centella, Echinacea, Gingko (the tree which thrives on pollution, which is why there are so many in NYC), Ginseng, Milk Thistle, and Tumeric. Like I said, it's main focus is on 'guarunteed potency herbs.'
The author laments, however, that not enough scientific research has been done on echinacea.
On page 60, under 'Route of Administration' the author states; "The guarunteed potency echinacea is currently available only as capsule." It doesn't mention how this capsule is prepared. I would assume that it is either powdered (no mention as to either root or leaves, but i assume root) or freeze-dried (scientifically known as 'lyophilized').
The author states under the heading 'Toxicity;' "Echinacea does not appear to be toxic even at very high doses. Incidentally, heavy use of echinacea may induce temporary infertility in the male." And then the author goes on to the reason why.
To anyone that is interested, there are 39 references to scientific articles at the end of the echinacea section. i will send a xerox copy of this index to anyone who emails me for my address and then sends me a self addressed stamped envelope. There are a few references to the isolation of the polysaccharides in echinacea. You can discover their methods of extraction, if you wish. Also, I have lots of scientific literature at my disposal, i will help anyone find an article if they want (but i have time limits, don't expect expediency, please).
This is a great book for the herbs in it, especially in dosage and delivery. For echinacea it suggests that mega-doses are not necessary, only moderate doses. (in other words, increased efficacy was not found by increasing the dose). It's suggestion is two to four 125mg capsules per day. A few weeks on then a few weeks off. It states that this is the recommendation of most European manufacturers of echinacea.
