But he is being taken to court by trading standards officers under the Cancer Act of 1939, which bans advertising offers to treat cancer and carries the threat of a three-month jail sentence.
He says he found 17 years ago he could 'stimulate a healing response' in patients using the laying-on of his hands and has since treated 'tens of thousands' of people and animals, with 13,700 waiting for his services at up to £30 a session.
He also claims he can cure people around the world using 'distance healing'.
This is the BBC Watchdog show in which they run tests to see what people do. In this case, the person whose website makes great claims was asked to determine the problem with a horse.

Not only does Adrian Pengelly claim to have magic hands he also says he can talk to the dead.
He was taken to a house with quickly rigged special effects to make noises and open a cupboard. Adrian became convinced there was a ghost and he had to go.

He soon repeated his claim to be able to cure up to 65 per cent of cancers. But then, shockingly, tried to dissuade Helen from having chemotherapy.
