I am not sure about the exact year , but this product came in the markt with a bang !
a lot of advertising on TV and Radio in eighties , it was a kind of mixture ( Unani medivine) for elderly people to remain healthy .
The Ads were quite funny , showing a small girl singing to her grand father( a comedy characther with fake hair and beard ) :
Nana Ji merey Nana Ji
Dekhiye main kya lai
Shahiii , Shahiii
Tayyebi Ki Shahi !! 
I remember that Shahi became very popular .
