> green and black tea if made fom the same leaves would be same caffeine and same fluoride.. black is just green cut first, which allows the leaves to oxidise, developing the flavour.
> However teas are made form different leaves, and trees ..so the actually amount of fluoride and caffeine does vary between teas. They don't state the fluoride content, some state naturally lower caffeine.. or pesticide freeI wasn't talking about *flouride*; I'm not really concerned about that. I'm talking about the active *flavinoids* (call them catechins, phytochemicals, active herb components, whatever) that exert some chemical effect on my body.
A large fraction of these flavinoids are destroyed when black tea is oxidized and processed. This would account for the more potent effects of green tea -- effects that I've experienced.
