Dynamic Accumulators, Part II

Back in February of last year, I wrote about Dynamic Accumulators and speculated about the source of much of the information that circulates about dynamic accumulators.  Since then, I’ve had an educational and enjoyable email exchange with Robert Kourik who has confirm that he is the source of material like that shown at http://oregonbd.org/Class/accum.htm.  He worked with the information that was available at the time.  Just after the book was published he discovered Dr. James Duke’s Phytochemical and Ethnobotanical Databases – http://www.ars-grin.gov/duke/ and quickly realized that much of what he had written in about dynamic accumulators was inaccurate.  Some plants in his table did accumulate the nutrients ascribed to them but many did not.  And more importantly unlike Duke’s data, his chart did not contain parts per million information which makes it impossible to focus on the best accumulators.

There was only one edition of Mr. Kourik’s book so there was never an opportunity to revise the data.

Hopefully, Mr. Kourik will update his original information.

Note: In addition to James Duke’s database,  Mark Pedersen‘s Nutritional Herbology : A Reference Guide to Herbs contains hard data such as this for comfrey.
