It's doubtful that the 500g tub is the full-on, concentrated, pure form of hing, RD (that comes in much, much smaller quantities, as it's so intense that just a pinch is most definitely all you need).
I'm guessing that it's more akin to the Natco hing I've got sitting alongside the wee jar of pungent stuff. If so, then it has other ingredients added (Gum Arabic, Ground Rice, Turmeric) and isn't anywhere near as strong.
When a recipe calls for a pinch of hing, I use half to one teaspoon of the Natco.
The contribution it makes is that as it cooks its pungency diminishes and it takes on an onion/garlic flavour hit. It's aslo supposed to be extremely good for the digestion, and makes you impossibly attractive to women.
