Herbal Jelly is a black coloured slightly bitter form of jelly, made of all natural ingredients. A chinese form of food, it is tasty to some, but others find it too bitter. Honestly to me, it isn't that bad, actually pretty good! Herbal Jelly is said to be a cold food, so eat it in the summer when you need to cool down.
It's found in (usually) chinese stores in forms of a drink, just jelly, and more.
'Hey mom, it's really hot. Can you buy some herbal jelly at the store?'
'I LOOOOVE herbal jelly! Try some!'
