  "content": "Controversial 'Treatment' at Battersea Park Clinic Raises Alarm\n\nAlastair Jessel, who operates the Battersea Park Clinic in south London, has drawn scrutiny for offering a highly controversial and scientifically unproven \"treatment\" for cancer. This method involves enclosing naked individuals in plastic bags and exposing them directly to chlorine dioxide gas. While chlorine dioxide is touted by some as a \"miracle cure\" for various ailments, including cancer, HIV, Covid-19, and autism, there is no credible scientific evidence to support these claims.\n\nJessel discussed this unusual practice on a podcast earlier this month, stating, “Having people naked in a bag, which in a clinic situation is probably what a lot of doctors have to face, but as an entrepreneur sitting in front of a naked person in front of me is something I hadn't sort of planned on doing in the last few years, but what it's achieving has been really quite incredible.”\n\nAndreas Kalcker's 'Protocol G' and Its Dangers\n\nTypically, users of chlorine dioxide ingest several drops of the solution daily. However, Jessel is administering a different, rarely used \"protocol\" first proposed by Andreas Kalcker, a German man who has been a primary advocate for the bleach-like solution in recent decades. This treatment, known as 'Protocol G', entails sealing people naked in a plastic bag from the neck down before exposing them directly to undiluted gaseous chlorine dioxide.\n\nJessel revealed on the podcast that he had consulted a private messaging group of other chlorine dioxide influencers to see if anyone had attempted Kalcker's so-called Protocol G, receiving no responses. He admitted, “Protocol G, obviously, is probably the most dangerous protocol out of all of them,” adding, “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.”\n\nNotably, Kalcker's website, which details the uses of Protocol G, makes no mention of cancer treatment. Kalcker told TrendKia, “Properly applied, with the straightforward precaution of avoiding vapor inhalation, it is a well-tolerated procedure.” He dismissed Jessel's description of the treatment as dangerous. While declining to comment on the efficacy of this treatment for all cancers, he did state that for skin cancer, Protocol G would be “directly relevant.”\n\nMedical Experts Issue Warnings\n\nCaroline Geraghty, a senior specialist information nurse at Cancer Research UK, expressed serious concerns regarding this \"treatment.\" She stated, “Currently there is no scientific evidence that chlorine dioxide gas exposure is a safe or effective treatment for people with cancer. 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.”\n\nJessel did not respond to a detailed list of questions from TrendKia, instead simply writing, “I can only refer you to protocol G in Dr Andreas Kalcker’s book Forbidden Health. That is all I do.”\n\nJessel's Background and Contradictory Claims\n\nJessel, whose father received a knighthood from the British royal family, previously worked as a stockbroker and owned a tile business before venturing into ice-cream entrepreneurship. Despite lacking any medical or scientific background, he registered the Battersea Park Clinic with Companies House in December 2021. Initially, the clinic offered treatments using scalar waves, based on an unproven pseudoscientific concept suggesting invisible energy can heal various ailments.\n\nIn an interview on The It’s All Good Show, Jessel claimed he became an expert in alternative therapies by watching “probably 150 to 200 hours worth of videos on how to heal people holistically.” Discovering that only 70 percent of his clients benefited from treatments like scalar waves, Jessel began exploring other options, including red-light therapy and a hyperbaric oxygen chamber, which tennis star Novak Djokovic used during a visit to the clinic last summer. A Facebook post on the Battersea Park Clinic account featuring Jessel with Djokovic has since been deleted, though a post on Jessel’s personal Threads account remains online. Djokovic did not respond to a request for comment.\n\nJessel claims that his most significant discovery came in 2024 with chlorine dioxide. In an interview with US anti-vaxxer Robert Yoho last year, he declared himself “the UK’s Mr. Chlorine Dioxide” and asserted that his clinic had “become the go-to holistic place if you have cancer.”\n\nHe told The It’s All Good Show that he believes cancer has nine causes, including stress and an unhappy marriage. “We all have cancer growing up every day, but our immune system keeps destroying it,” Jessel said. “When you get stressed, when somebody at work stresses out, when your wife or your husband drives you absolutely mental, and you get stressed, that's when the cancer appears.”\n\nInvestigations and Legal Challenges\n\nJessel initially distributed bottles of chlorine dioxide to his clients for treating cancer and Covid. However, according to Jessel, his practice was raided by the Food Standards Agency and Trading Standards in December 2024. He alleged to Yoho last year, “Big Pharma had sent someone with a concealed recording device to secretly record my staff discussing chlorine dioxide.”\n\nTrendKia reviewed an email from July last year from a Trading Standards officer, which confirmed that bottles of chlorine dioxide were found displayed in the clinic. A subsequent visit found no bottles for sale, and an employee informed an undercover officer that the clinic no longer offered it as a treatment. The Food Standards Agency and the Trading Standards officer who led the investigation last year did not respond to requests for comment.\n\nThe UK’s Cancer Act 1939 prohibits non-medical professionals from advertising cancer treatments or cures. Around the time of the Trading Standards investigation, references to chlorine dioxide’s efficacy were removed from the clinic’s website, though archived versions still show them. The clinic’s Facebook page continues to promote chlorine dioxide, including a link to a talk by Pierre Kory, a prominent anti-vaxxer previously praised by Kennedy.\n\nConcerns from Victims and Activists\n\nFiona O’Leary, an activist based in Ireland who has long highlighted the dangers of chlorine dioxide and reported Jessel’s use of the chemical to Trading Standards last year, voiced her distress. She stated, “Vulnerable cancer patients are being experimented on, gassed with bleach, naked. It's hugely upsetting for those who have experienced cancer in their families, to see this happening and the authorities doing nothing to stop it.”\n\nNatalie Passant, whose father underwent treatment at the clinic for advanced prostate cancer in 2024, spending approximately $5,000 before his passing in February 2025, found Jessel's claims hollow. She remarked, “They are manipulative and guiding very vulnerable people away from medical advice and encouraging them to invest a lot of money in these treatments.” While Jessel did not respond to TrendKia’s questions regarding Passant’s father’s treatment, he did reply to her criticism on a Google Review. Jessel wrote, “I never encouraged your father to forgo essential medical treatment such as radiotherapy. We do not treat, heal or cure anyone and at no point did I ever sit down with Nigel and give him ‘advice.’”\n\nHowever, Jessel, who has described his own clients as “quite stupid” regarding their ability to self-administer chlorine dioxide treatments, has repeatedly contradicted this statement in podcast appearances where he openly discusses treating, healing, and curing his clients. Jessel told Yoho last year, “We are treating lots of people for lots of different illnesses. I would say now, probably 50 percent of my clients have cancer.” The Care Quality Commission, Wandsworth Council, and the Medicines and Healthcare Products Regulatory Agency did not respond to TrendKia’s requests for comment.\n\nWhat this means for you\n• Across India: Individuals seeking alternative cancer treatments should exercise extreme caution and always consult with qualified medical professionals before trying any unproven remedies, as these can be dangerous and delay effective care.\n• In London: Residents should be wary of clinics offering unconventional treatments and verify their scientific backing and regulatory approvals to ensure their safety and avoid potentially harmful practices.\n\nQuestions & Answers\n\n1.
