Gold has strong immune-boosting properties

That’s why king’s in ancient times used to keep contact with gold.

There is a description of SUVARNA-PRAASHAN in our scriptures where we prepare tasty paste having gold ash in it.

Few herbs in it are:

Vekhand + Desi cow ghee + Natural honey in unequal proportion + gold ash & many other herb.

This combination is had during PUSHYA-NAKSHATRA where effect of having such immune-boosting is maximum. So baby is made to have it in that time.
