Medical Experts Warn Against Banned ‘Self-Healing’ Coach Barbara O’Neill in UK and Ireland

Medical Experts Condemn Scheduled Tour by Banned Naturopath Barbara O’Neill

A multi-day event featuring a self-described naturopath permanently banned from providing health services in Australia is scheduled to begin next week at the City North Hotel and Conference Centre in Gormanstown, Co Meath. The upcoming lectures have triggered a coordinated warning from prominent doctors, academic leaders, and cancer charities across Ireland and the UK, who caution that the speaker’s commentary poses tangible and life-threatening risks to vulnerable patients.

Barbara O’Neill, who commands a social media audience of 3.6 million Instagram followers and 356,000 YouTube subscribers, lectures internationally on natural self-healing and remedies. Tickets for the three-day Meath event range from €70 for a single day to €195 for a three-day bundle, with premium packages priced up to €115 daily or €320 for the full conference.

New South Wales Bans O’Neill for False Cancer Claims

In 2019, Australia’s New South Wales Health Care Complaints Commission (HCCC) issued a lifetime ban preventing O’Neill from providing any health services, either voluntarily or in a paid capacity. Investigators concluded that she never held membership with any accredited professional health organization and lacked relevant health degrees or diplomas. The inquiry found she failed to keep consultation records, falsely claimed an ability to cure cancer, and treated clients in an unsafe manner.

O’Neill has previously told cancer patients their illness is a fungus curable with bicarbonate of soda rather than conventional medicine, according to investigative findings. She has also discouraged mainstream cancer treatments, vaccinations—claiming they cause autism and cot death—and antibiotics for pregnant women with Strep B. A spokesperson for the HCCC stated that while the prohibition does not apply overseas, the agency urges the public to remain wary of health misinformation.

Coordinated Warnings Issued to Irish and UK Venues

Medical professionals and charity executives addressed a formal letter to the venues hosting O’Neill’s tour. The letter was coordinated by David Robert Grimes, a science communicator and adjunct associate professor in biostatistics at Trinity College Dublin. Signatories include Orla Dolan, chief executive of Breakthrough Cancer Research; Colin Doherty, head of the school of medicine at Trinity College Dublin; Derek Power, consultant medical oncologist in Cork; Jennifer Feighan, chief executive of the Irish Nutrition and Dietetics Institute; and Susan Smith, professor of general practice at Trinity College.

The signatories warned venue operators that O’Neill spreads dangerous health fictions to susceptible audiences by using the legitimacy of respectable establishments. The letter asserts that such misinformation harms patients and that O’Neill demonstrates a remarkable callousness toward those consequences. Following the Irish dates, O’Neill and her husband, Michael, are scheduled to appear at the Founders and Future festival at Glasgow University Union.

Organizer Responses and Defense of Tour Bookings

Michael O’Neill defended the tour in statements reported by The Guardian, asserting that the Australian HCCC ban suffered from serious legal flaws and political bias related to pharmaceutical funding. He maintained that his wife never received a single patient complaint of harm.

University and venue representatives defended their hosting decisions based on contractual compliance and free expression policies. A Glasgow University Union spokesperson stated that event organizers entered into a booking contract and remain free to use spaces as long as activities align with internal policies and the laws of Scotland and the UK. Meanwhile, Prof. Liam Smeeth, director of the London School of Hygiene & Tropical Medicine, said that while he opposes outright speaker bans due to potential counter-productivity regarding free speech, he considers O’Neill’s unscientific claims capable of causing great harm.
