I agree with Escoce that you personally may or may not want the dust form of tea, but it can be used in the home. Using it is a little different from leaf teas. If you are used to steeping whole leaf (or at least, large piece) tea and then pouring through a wire mesh tea strainer, you will find that the tea dust goes straight through the mesh. You need to strain it through something finer.
Many (most?) tea bags are made of a sort of filter paper, some are made of very thin silk. You can place a clean square of silk in your tea strainer (large enough that it completely covers all the mesh with some to spare) and pour the tea through that, or you could also use a paper coffee filter if you have those available.
There is also something called a tea sock which is basically a tube of thin fine-mesh fabric (sometimes silk, sometimes nylon or polyester) closed at one end. If you use this, you put the tea dust in the "sock" and steep the tea using the tea-sock the way you might use commercial tea bags.
