Is Prescribing medicines through online portal illegal in India?

This is a two part question-

Buying medicines online may be legal, provided a valid doctor's prescription is uploaded and is assessed by an authorized merchant, prior to despatch/sale of medicines in question. 

Prescribing medication online becomes complex because the medical laws only allow a licensed practitioner to prescribe medication here also there are different classes of medication some which are allowed to be sold over the counter, and others which are 'controlled.'

we would need some more details of the business model to understand what the company actually intends on doing.
