Mark Blumenthal hosts his famous “Stump the Herbalist!” session at the Natural Products Expo West in Anaheim this week from 2:45 to 4:00 on Thursday March 17, in Room 204B at the Convention Center. In addition to Mark as moderator, the session features well-known herbalists Christopher Hobbs, Brigitte Mars, Ed Smith, Mindy Green and Roy Upton. Mark always creates a collection of useful, obscure and esoteric questions, and the herbalists offer straight and, at times, whimsical answers. When none of the panel knows the answer, the audience is invited to answer. At the end, an herbalist (or the audience as a total) is selected as the winner. Everyone learns and has fun at the same time. Over the years this session has proven to be one of the most enjoyable and entertaining sessions for Expo attendees. Please try to attend even for part of the session.
