Green tea to lower blood pressure?

I have heard that drinking red tea (Roselle) may help lower blood pressure. Is this true?

No, you heard wrong. Millions of people seem to think that drinking tea is good for health. So far, there is no evidence that tea is anything more than a social beverage. Over the past 3 decades, hundreds of types of tea have been developed with hyped up health benefits. The manufacturers of tea products are simply scamming people with false claims about its health benefits. Orientals have been drinking tea for centuries and their health does not appear to be any better than Westerners. There is no harm in drinking tea but if you expect your blood pressure to drop, you are sadly mistaken. Marketing tea for health benefits is now a major scam. Every type of tea is being hyped up to cure everything under the SUN. Unfortunately, there are many gullible and stupid people who believe such crap and fall for unproven therapies.
