Dr. Bouko Levy presented the very first seminar on Homeopathic Drainage in North America in Vancouver, BC, in 1988 and his first complete course in Toronto, ON in the early 1990’s.
This course was called “Homeopathy and the new Biotherapeutics” and included what he then called Biotherapeutic Drainage.
Dr. Bouko Levy later on renamed “Biotherapeutic Drainage” as “Homeopathic Drainage” to better reflect the nature of the substances used as drainage agents.
This course is now available online.
His books have been digitized and are available for download from this site.
