A London clinic offering chlorine dioxide “Protocol G” for stage 4 cancer has drawn alarm after the method reportedly seals patients—naked from the neck down—in plastic bags and exposes them to undiluted chlorine dioxide gas, even as the provider admits it is
On the podcast. the operator of a south London clinic described what happens during the treatment: people are sealed naked from the neck down inside a plastic bag and then exposed to the gaseous form of chlorine dioxide. He also said he hadn’t planned on doing it in a clinic setting. The person administering it called the approach “dangerous.”.
The clinic is the Battersea Park Clinic, run by Alastair Jessel. He is treating patients with stage 4 cancer using a method he says is “quite incredible. ” despite acknowledging the risk of putting a person in a bag in a clinical setting. Jessel’s description comes from earlier this month. when he spoke on a podcast popular among believers who treat chlorine dioxide as a miracle solution—used. they claim. for illnesses ranging from cancer and HIV to Covid-19 and autism.
Jessel administers what he calls a different “protocol” than the typical one. The common approach, he said, involves users ingesting several drops of chlorine dioxide solution each day. His method is instead based on a little-used protocol first put forward by Andreas Kalcker. a German man who has promoted the bleach-like chemical for decades.
Protocol G. as Jessel says it is carried out. includes sealing people naked in a plastic bag from the neck down and then exposing them directly to undiluted gaseous chlorine dioxide. Jessel said he had asked a private messaging group of other chlorine dioxide influencers if anyone had ever tried Kalcker’s so-called Protocol G and that nobody responded.
“Protocol G, obviously, is probably the most dangerous protocol out of all of them,” Jessel said. He added: “Nobody’s ever done it. So I don’t know whether I’m the first person in the UK to do it, but I’m definitely a rarity.”
On Kalcker’s website, however, Protocol G is not described as a cancer treatment. Kalcker instead tells WIRED that “Properly applied. with the straightforward precaution of avoiding vapor inhalation. it is a well-tolerated procedure. ” and he dismisses Jessel’s characterization of the process as dangerous. Kalcker will not comment on whether Protocol G works for all cancers. but he says that in relation to skin cancer. the protocol would be “directly relevant.”.
Cancer Research UK disputes the premise that anyone can treat cancer this way. “Currently there is no scientific evidence that chlorine dioxide gas exposure is a safe or effective treatment for people with cancer. ” said Caroline Geraghty. senior specialist information nurse at Cancer Research UK. She added: “Taking unproven treatment or remedies for cancer instead of those that are medically approved could affect how well the treatment works and have dangerous side effects. It’s incredibly important that people speak with their cancer doctor, GP, or specialist nurse before trying any alternative remedies.”.
When asked for further details about the treatment, Jessel did not respond to a detailed list of questions. He instead wrote: “I can only refer you to protocol G in Dr Andreas Kalcker’s book Forbidden Health. That is all I do.”
The wider chlorine dioxide “miracle cure” movement has existed for decades. and it is built on claims that the substance can treat a wide range of illnesses and disorders. These chlorine dioxide solutions have been sold under different brand names. including Miracle Mineral Solution. with no credible evidence supporting the claims.
Still, momentum has grown again in recent months. Over the last year, interest in chlorine dioxide has surged after US health secretary Robert F. Kennedy Jr. mentioned it when questioned about President Donald Trump’s Operation Warp Speed during his Senate confirmation hearing in January 2025. Around the same time. a year ago. the Food and Drug Administration removed a warning about the substance from its website. The FDA says the removal was part of a routine process of archiving old pages. but the change has had an effect—emboldening the bleacher community.
The human stakes in all of this are hard to miss: patients described as being treated for stage 4 cancer are being sealed in bags and exposed to undiluted chlorine dioxide gas. even as the person administering the approach says it is dangerous. and cancer specialists say there is no scientific evidence it is safe or effective.

So basically they’re putting sick people in a bag and doing bleach gas?? That’s insane.
I saw something about chlorine dioxide and thought it was like a “detox” thing. But if it’s undiluted gas and they’re naked in plastic bags… yeah no. How is this not immediately shut down?
Wait “protocol G” like… letter G? That sounds made up. Also stage 4 cancer patients already have it bad, so blaming the bag seems obvious but like, maybe it’s actually the chlorine stopping the disease? Idk I’m not reading all that. Just sounds like people are being used for content.
They said it was “dangerous” and he still did it in a clinic? Sounds like one of those influencer cult medical things where they say it’s a miracle. If it’s on a podcast, it’s probably half conspiracy, half desperation. Also how can they say undiluted chlorine dioxide gas like that and not expect lawsuits or worse? I don’t trust any “protocol” that involves sealing somebody in plastic.
