It's really interesting. My Cousin (son of the same Uncle) is an oral surgeon and the only "legitimate" Doctor that I've encountered that wholeheartedly endorses the value of this type of therapy. He's seen it work over and over again his entire life, and in his 20 years in practice regularly refers patients to his Dad.

It's another one of those slowly disappearing talents that modern medicine views as too archaic. When people like my uncle are gone, so is all that knowledge and skill. It's a real shame
