London Clinic Gasses Stage 4 Cancer Patients With Chlorine Dioxide as UK Regulators Cite No Authorization

Summary
Battersea Park Clinic in south London is putting stage 4 cancer patients naked in sealed plastic bags and exposing them to chlorine dioxide gas, a bleach-like chemical its operator calls the "most dangerous" protocol.
Alastair Jessel said he adopted the little-used "Protocol G" promoted by Andreas Kalcker even though no scientific evidence shows chlorine dioxide gas is safe or effective against cancer, according to Cancer Research UK.
UK regulators said chlorine dioxide has no relevant marketing authorization as a medicinal product, while the Care Quality Commission said it could not act because it found no listed healthcare professional involved.
The clinic had already drawn scrutiny after a 2024 Trading Standards investigation found chlorine dioxide bottles on display, and archived website pages and social posts continued promoting the substance for cancer.
The case highlights a wider revival of chlorine dioxide pseudoscience, which campaigners say is exploiting vulnerable patients; one family said a relative spent about $5,000 at the clinic before dying in 2025.

The Battersea Park Clinic Incident: Deadly "Miracle Cures," Patient Exploitation, and the Urgent Need for Stronger UK Health Regulation
Overview
In 2024, The Times uncovered the dangerous activities of the Battersea Park Clinic, operated by Alastair Jessel from his home in Battersea. Jessel, who had no medical training and was formerly an ice cream entrepreneur, promoted a so-called 'miracle cure' called 'Protocol G' to terminal cancer patients. This risky treatment involved sealing patients inside plastic bags and exposing them to chlorine dioxide gas, a hazardous industrial chemical. The clinic’s practices, exposed by the investigation, highlighted serious risks to vulnerable patients and sparked immediate regulatory scrutiny and public concern over patient safety and medical ethics.
