Teasenz is a China-based company that ships tea all over the world, both as a retailer and wholesaler. What distinguishes their tea is that they only sell loose leaf tea (no tea bags), and they only sell pure tea (no blends). They guarantee that all of their teas are authentic and shipped direct from China. They also have a great shipping rate of $5 flat rate shipping to anywhere in the world for packages weighing less than 4.4 pounds.
Teasenz only sells Chinese tea, not teas from other countries. You can find lots of different varieties of Chinese teas such as black tea, green tea, white tea, oolong tea, and herbal tea. The herbal teas include goji berry tea, rose flower tea, honeysuckle tea, and many other pure teas. The descriptions on the website explain the different health benefits of the herbal teas. Personally, I'm tempted to try some of the different green teas to see which I like best.
I was glad to hear about Teasenz, and they would also be a good site to check out for gift ideas for friends who like tea. Their tea ware collection includes infusers, strainers, tea pots, and much more.
