Rama Prasad prescribed the medication to a three-year-old which contained quantities of the toxins which are unacceptable by Australian standards.
The Health Care Complaints Commission has found there was no evidence for this treatment.
It also said that as a “non-registered health practitioner” he misrepresented being a doctor.
Mr Prasad also provided care without the necessary qualifications and prescribed Ayurvedic medicine that he had a financial interest in without disclosing it.
Ayurveda is a pseudoscientific alternative medical system with roots in India.
“Sadly, this is not uncommon, there are a lot of these types of quack practitioners out there that are really preying of families, particularly of young children who have just been diagnosed with autism,” Nicole Rogerson, CEO of Autism Awareness Australia said.
The Commission has deemed Mr Prasad “poses a risk to the health and safety of members of the public”.
He is now “permanently prohibited from providing, or causing to be provided, any health services, either in paid employment or voluntarily, to any member of the public”.
