People have been warned about a viral video from a Saudi doctor claiming to have found a cure for COVID-19.

The warning came from Health Ministry spokesman Dr. Mohammed Al-Abd Al-Aly after the doctor in the video said he had found the right medicine for COVID-19 using different herbal components. He also said that his medicine had been clinically tested on 100 critical cases after he was given permission to carry out the experiment.

“We would like to clarify that the Kingdom has specialized bodies and controls for research,” Al-Abd Al-Aly tweeted. “In case there are sound scientific results, the research passes through professional accreditation and scientific publication after their evaluation. We warn against any claim that violates the controls, and those who carry it will be held accountable according to the regulations.”

Al-Abd Al-Aly has previously warned against such rumors and the use of home remedies that could do more harm than good.
