They have raised concerns about a psychic television medium that says "ghost doctors" can cure pain due to arthritis.
Jeanette Wilson, former bank manager, is turning to the UK to make statements, including the possibility of suppressing the need to wear spectacles, while spreading messages against vaccination.
Mrs. Wilson, originally from the United Kingdom, but based in New Zealand, told a recent public in Chester that he would only "talk about the camera" on the "best for scar tissue", so that "business standards are not converted in all."
His ongoing tour includes dates at the Hotel Village in Birkenhead, Wirral, where customers can pay £ 20 for a two-hour "psychic surgery" demonstration.
In a part of the show, Mrs. Wilson speaks to a woman who complains that she has arthritis and tells the audience: "I've been doing this for 25 years, I have not yet met anyone that anything Arthritis can not be completely eliminated.
"I have seen all kinds, I have seen people with really distorted fingers that look horrible, they return to normal."
In another section, he asks the public to check a YouTube video that says he helped a woman suffering from degenerative disease of multiple sclerosis.
During the Chester show, Mrs. Wilson explains to the public that a deceased surgeon, named Dr. Augusto de Almeida, "works with her" to cure people.
In a segment, talk to a woman with chronic ankle pain due to an old injury.
She says: "So everything that happens with healing is not very difficult for healing. White viscous because the energy extracted from the patient, the healing receptors, do not contaminate my energy fields.
"Because the guides that work with me I have a team of guides that work with me. They are the ones that move their hands, they are the ones that sometimes cause words to emerge here, give lessons."
The middle and 56-year-old author also promotes products that include purple rice powder, an add-on that those responsible say they benefit from health, available at € 85 for each bath from their website.
In a part of his Chester series, he suggests that the elderly people recommend "purple dust" to "keep their vibrations" and say to a member of the public: "We need you in purple dust, right?"
The criticism of the affirmations of Ms. Wilson has been shared by The Good Thinking Society charity, which promotes scientific skepticism and is concerned that some of its guests avoid the main medical treatment.
Michael Marshall, director of the project in society, told ECHO: "We are worried that Mrs. Wilson's program could encourage sick and vulnerable people to come so that they can do so called healing, without proper proof That these cures are effective.

"Those patients may be convinced of thinking that the solution to their health problems does not reside in the advice of their doctors or in any qualified medical professional, but in the healing powers that Mrs. Wilson claims to have and the expensive products they see.
"Given that there has never been any evidence that someone can be cured through a connection with the so-called spiritual world, patients who trust their health to anyone who says they use psychic energy to treat any illness or risk of injuring the bad weather. Wasting their money and even boosting their conditions. "
Marshall raised more concerns about a booklet that was delivered at the fair that contained links to anti-vaccination websites, suggested that vaccines in New Zealand were linked to Alzheimer's disease and that 5G technology was " weapon ".
He said: "We are also very concerned that the deceptive and potentially dangerous claims made by Mrs Wilson regarding the safety and efficacy of vaccines could persuade people not to vaccinate their children.
"At a time when we are seeing a resurgence of diseases that can prevent vaccines, the spread of the wrong information against the vaccine could endanger the health of children."

Marshall told ECHO that he had referred to Mrs. Wilson's activities to business standards.
Mrs. Wilson, who appeared on a television show in New Zealand called "Dare to Believe," told ECHO that his critics "reported badly" on his activities and made "false statements" against her.
He also said: "The reference to talking outside of a camera on a scar tissue product made me very careful not to violate the commercial standards indicating to people about a product that I have used and seen that they do not see me.
"I am aware of the commercial standards of the United Kingdom and I work with them."
