Guardian investigation profiles Barbara O’Neill wellness event

scienceOct 18, 2026883

The Guardian sent an undercover reporter to a five-day wellness conference at the De Vere Cranage Estate hotel in Cheshire where Australian influencer Barbara O’Neill promoted anti-medical advice, telling one audience member with lupus “keep away from the doctor” and dismissing antibiotics, vaccines and scientifically proven cancer treatment. O’Neill advised treating a tumour with a castor oil compress applied externally, and delivered long, scientific-sounding explanations about the glycocalyx while also mixing Bible verse into sessions on the immune system. Tickets for the residential retreat cost up to £1,300 and the reporter observed four sessions in one day, including a session titled Barbara Under Attack. O’Neill has 3.6 million Instagram followers and 1.7 million on Facebook and was banned from providing health services in Australia in 2019 after authorities found she made misleading, dangerous claims that posed a risk to public safety. Prominent doctors and scientists told the Guardian her advice is dangerous and could kill, and experts in the UK and Ireland have warned venues against hosting her appearances. The Guardian’s account shows how O’Neill has shifted from Australia to unregulated events overseas where her teachings reach large audiences despite the Australian ban.

I have 20 years on this idiot and COPD, and I'm pretty sure I'll still outlive him. The good thing about people like this is that it's self solving problem!

I work in a nuclear facility, he can come sit in one of the shielded cells holding nuclear sources if he really wants a full-body dose (if he can convince the RSO to allow him)

Such people who dismiss science, antibiotics, vaccines are a threat. Their advice fatal.

If you listen to influencers instead of medical doctors, maybe it's best to let nature take its course.

“Sometimes scans are not right,” replies O’Neill, who advises the woman to treat the tumour with a castor oil compress – kitchen roll soaked with high viscosity oil from the castor plant – on the outside of the body. www.theguardian.com/society/2026...

"...O’Neill says she is driven by God, who she believes spoke directly to her..." Another 'supposedly reliably apparently religious based evil/deranged person' literally putting a spell on gullible and desperate people.
