Has anyone heard about Red Tea, or used it?

I been told that Red tea, also known as "rooibos," has a host of benefits, including immune system health, helps reduce aches and pains, stomach cramps, headaches, allergies, asthma, insomnia, eczema, high blood pressure,and cancer fighting properties. Research has shown that rooibos is not only good for your immune system, it has weight loss benefits too. Brewed, Rooibos looks red but doesn't really taste like tea – it has a slightly sweet and fruity flavor. I been thinking about buying some, and was wondering if anyone has tried it, and what you think about it - LINK
