Ayurvedic Medicines for Autism?

In the December 8th Bangalore Times, the need to research ayurvedic treatment for autism is noted:

For children identified with autism spectrum disorders, ayurveda has a range of internal medications and external treatments that are done for an average of 21 days and repeated periodically. These contribute significantly to improved social interaction, improved eye-to-eye contact, reduced hyperactivity, improved communication and also improvement in metabolism and other associated complaints…..

Many ayurvedic medicines can contain dangerous quantities of heavy metals, including lead, mercury, thallium and arsenic, a recent study in the International Journal of Environment and Health reported.

Be careful what you “treat” autism with.
