Teas in general are good for health as these have antioxidants (Flavonoids and Catechins) that scavenge free radicals. Our body ceates free radicals as a bi-product of liviing. These free radicals attempt to oxidize lipids, contributing to old-age diseases. Catechins have been shown to be more effective scavengers than other antioxidants like vitamin C and E, making them very good for human systems.

Teas in general are anti-bacterial, anti-viral, anti-depressant and boost immunity against cancer and other diseases. They also control bad cholesterol and artery clogging, lower blood pressure, relieve stress and help in digestion. Some teas also prevent tooth cavities and have anti-aging properties. However, the extent of health benefits varies based on various factors :

Presence of anti-oxidants in the tea, which in turn depends upon the way tea is processed and fermented. For example, White and Green teas are least processed, and have high levels of anti-oxidants than Black teas. Oolong tea is somewhere in between.

Whole leaves' are less oxidized (and therefore have higher levels of ani-oxidants) than 'Broken leaves', 'Fanned' and 'Dust'. Most of the common teas available in the market are made of 'Dust'

Organic teas are better as these don't have pesticides.

Once milk is added, tea loses its health properties to large extent.
