A mum of three in the UK is being investigated after allegedly giving her autistic son bleach enemas to cure him of autism – a shocking practice which also has links to Australia.

A church with two chapters in WA and NSW promotes bleach-based 'miracle cures' for conditions such as HIV, malaria, cancer and autism.

The Genesis II Church, which has its headquarters in a "compound" in the Dominican Republic, calls itself a non-religious "church of health and healing" which works to "benefit mankind" through "bringing health and healing to the sick" using "technologies … blocked by the American Medical Association and US Food and Drug Administration".

The church is a proponent of using MMS — a potentially lethal solution of sodium chlorite (found in household bleach), acid and water used for cleaning or water purification — to "cure" chronic conditions.

The sale of MMS as a health product is illegal in Australia, and the Therapeutic Goods Administration (TGA) said it "poses a serious health risk if consumed by humans".

The Australian Medical Association have also previously called for such "magic potions" to be banned, following the hospitalisation of four Victorians in 2014.

But, Genesis continues to advertise the drops online even listing sellers of the solution (including one in Australia) and encouraging people to pay $US200 to access an MMS video training course.

Concerning testimonies on the Genesis website are allegedly written by some of the "five million" people who have recovered from illnesses by using such "cleansing waters", including the mother of a sixteen-year-old boy.

"My 16-year-old son recovered from Autism by the use of Kerri Rivera's MMS/CD (chlorine dioxide) protocol", the testimony reads.

"I am now convinced that older kids and adults, tough nuts can all recover from autism as evidenced by so many recoveries in various CD forums".

The mother-of-three in the UK is currently under investigation by British police and social services after being reported for her comments on a secret Facebook group. There is no suggestion that she has links to Genesis church.

9Honey’s Jo Abi, whose nine-year-old son, Giovanni has autism, is calling on the authorities to do more.

"It’s so disappointing to hear about people talking about a cure for autism", she said.

"It isn’t a disease. It doesn’t need a cure.

"Clearly this particular 'cure' is ridiculous. Hopefully the authorities step in to put a stop to it.

"I would never try and fix or cure my son because he is perfect just the way he is."

9Honey contacted the Genesis II Church but they declined to comment on MMS and the treatment of autism.
