You can eat a whole bud cured and it will do little to nothing for you. It needs to be made available by dissolving it into a lipid and decarboxylated.
The trichomes would not melt into the liquid and if anything will just clog and stick to the side of the cup. Don't think the taste would be great.
Other THC teas I have seen in person use a capsule that had infused oil in it, or a bio-available extract that has been sprayed on the leaves/tea bag, never just cannabis leaves tried and chopped. If anything just make a none decarboxylated hash or keif extract and just eat it. Note in time it will start to decarboxylate a bit and also degrade, so keep it in the freezer if not useing it all right away.
There is a Indian drink that uses cannabis leaves, kinda like a tea, maybe take some inspiration off of that? Its legit the leaves though, not the buds.
