Not as far as I'm aware, I was given to understand that he genuinely accepted it, even went to the World Health Assembly and promoted it, amongst other 'alternative therapies' - either way, the way to deal with troublesome patients is to spend a little time to find out why they're so desperate for treatment, not to fob them off with pseudoscience.

As evidence, I cite the homeopathy garden in the Dumfries Hiouse estate - a few miles from my gaffe.
Ye, old Chairlie has done some remarkable things with the ex-ancestral pile; though he's had some daft ideas as well - creating a Scottish version of 'Poundbury' called 'Knockroon' has been less than successful.
Dumfries House seems to be an attempt by him to plump up his popularity as 'Duke of Rothesay' up here - and to some extent, amongst the literati, he has successded - though most of the locals treat him as a joke to be pitied
Chairlie and Cmalla have a flat in Dumfries House, which they use as an alternative to Sandringham or Balmoral.
