Speakers, Ralf Oettmeier, M.D., and Josef Vizkelety, M.D., DDS, of the Alpstein Clinic, in Switzerland, will give a comprehensive overview of the Alpstein Clinic concept from 6 to 8:30 p.m., May 21, at the Residence Inn Cambridge. This concept focuses on the most important pillars of whole-body medicine and dentistry: diagnosis of root causes, purification and release, regeneration and rejuvenation, and harmonization and awareness.

In addition, the two will discuss key themes from their recent book, Say Yes to LIFE! which offers clarity, innovative treatment approaches and hope for those suffering from chronic illness and cancer. This will be an interactive discussion with questions from the audience being encouraged by the presenters.

Bioregulatory health care is an innovative approach to holistic health care that combines medical and dentistry expertise to provide whole body care for a patient that includes mind, body and spirit. For people with chronic illness and cancer, this is an approach that can offer them relief from symptoms as well as get to the root cause of their issues to better treat the disease from multiple angles, not just with medication or invasive therapies.

Cost: $15 advance/$20 at the door. Special ticket package: $45 includes the book. Location: 120 Broadway, Six Cambridge Center, Cambridge. For more information, call 508- 748-0816 or visit bit.ly/SYTLTour.
