Autistic child

I saw this autistic (around 2 year old) boy few weeks ago. He was crying continously while waiting for his mom. He was very restless and clapped his hand continously.
I gave him diluted chammomile 5 ml TDS for 10 days.
Surprisingly when he came next to see me he was very calm. There was good eye contact. Mother informed he is now able to eat by himself, able to climb stairs and the best part is that he was able to call his mother – mama. Her mom was very happy with his achievement and want to continue the meds.
Amazing Dr Tariq!..tqsm sir!
