"Sap from the common garden weed petty spurge appears to treat non-melanoma skin cancers, experts are reporting in the British Journal of Dermatology.
The plant sap has been used for centuries as a traditional medicine, and the researchers wanted to put it through its paces in a proper clinical trial.
After a one month, 41 of the 48 cancers had shown a complete clinical response to the treatment, meaning no trace of the tumour could be found on clinical examination."
