Actually it is minus 5 stars...the Most bogus so called doctor in Kolkata. I would rate him as Fraud. The center looted more than Rs. 25,000 from us for 6 months package to cure my daughter's susceptibility to cold and infections and also speech delay. After treatment of 4 months I had to stop the medicines, as my daughter's health was deteriorating and she was becoming very irritable...NO improvement in anything. If you want to get robbed by frauds, then go to this center.
