The International Herb Symposium
We’re honored and grateful that almost 2000 participants joined us online for the 15th Annual IHS. Thanks to the addition of the online learning platform, more individuals than ever before have been able to access teachings! At the same time, we’ve deeply missed getting to gather with you in person – which is why we’re very excited to be launching the 16th International Herb Symposium as a hybrid event — taking place both online and in person at Wheaton College campus in Norton, MA, on June 9-11, 2023!
