CLAIM: MMS cures HIV. Jim Humble claims it cured "96- 97%" of a test group of 500 people with HIV in Malawi.

VERDICT: Hefin Davies of the Food Standards Agency: "We are not aware of any research that shows MMS is effective in treating HIV, or in fact in any other condition it is claimed to cure."

CLAIM: The claim that MMS cures HIV cannot be proved to be right or wrong because "you can't prove that a person has no HIV virus in their body".

VERDICT: Catherine Moore, a virologist at Public Health Wales: "This is not true because people with HIV can be and routinely are tested for the virus using molecular tests that show evidence of viral genes in the blood."

CLAIM: MMS can destroy cancer and the nausea caused by the drug helps patients "clear out the poison" through vomiting and diarrhoea.

VERDICT: Davies: "Again, there is no evidence MMS cures anything, and definitely not cancer."

CLAIM: When you get nauseous, you know the MMS is working. The website states: "You will be able to know if it is going to help you if you can continue to pass the nausea point and increase the drops."

VERDICT: Davies: "Given what the product actually is - bleach - we would expect people to be sick."

CLAIM: That the combination of sodium chloride and oxygen used in MMS is "harmless" and creates sodium chlorite, "the most powerful killer of pathogens known to man".

VERDICT: Davies: "It certainly is one of the most powerful. That is why we use it in bleach - and why it is actually very harmful to us."

CLAIM: It kills pathogens but leaves "friendly" bacteria alone.

VERDICT: Davies: "This is one of the unfortunate claims that people like this make. "A while back we found apricot kernels being sold, which produce cyanide in your stomach and that too was claimed to only target cancer cells."This is, of course, impossible. Unfortunately, while MMS will kill bad bacteria, it will also kill everything else too."
