This comes from the web site that Webby quoted in the TMJ thread. It's
from Dr. Wartell's page of the same name:

Homeopathy

Many of our patients are being treated by homeopathic physicians. We are
aware that certain substances commonly used in dentistry can interfere
with your homeopathic medication efficacy. An example of this is the
mint flavoring used in some dental materials. If you are being treated
with homeopathic medications, please let us know, so that we can consult
with your homeopathic physician and plan to use appropriate materials
for you.

SO: what is the problem with mint based stuff in the mouth?
