What is the urdu name of bee pollen?

There isn't one single, universally accepted Urdu name for bee pollen. The most likely and understandable translations would be descriptive phrases rather than a single word. You could use something like:

* شہد کی پھولوں کی پالیں (Shahd ki phoolon ki palian): This translates to "pollen of honey flowers."

* مکھیوں کا پھولوں کا گھوارہ (Makhiyon ka phoolon ka ghuwara): This means something like "bees' flower dust/powder."

These options convey the meaning clearly. You'd likely need to explain what bee pollen is if using these phrases with someone unfamiliar with the product.
