>I'm starting to buy Artisan teas from a vendor in Shanghai.

Actually, I've heard many people say that buying these teas can be
harmful to your health because they have to add certain things into the
teas when making them; plastics to hold the shape of the "seed pod",
dyes, etc. Most people I've talked to only view the teas and never
drink them. I mean, it is just a bunch of flowers.
