Not sure about the brand. I have probably tried it before but it doesn't stick in my mind.
The only difference between loose leaf and a teabag is that you won't run the risk of swallowing some leaves if you use a teabag. I find that loose leaf tastes a bit better, but that is mainly because some teabags impart a bit of flavour from the paper they use.
Loose leaf can be prepared either by putting the leaves straight into your cup and adding hot water, or you can make it in a pot.

I see all my dead relatives seated.
I see my master seated in Paradise and Paradise is beautiful and green; with him are men and boy servants.
He calls me. Take me to him.
