I have tried both Rooibos and Green Tea, cannot abide either. I don't like sweet hot drinks so I think that is why I dislike the Rooibos as well as fruit teas. Green tea just tastes muddy to me but my son assures me it is a brilliant hangover cure. I have not had tea since my diabetes diagnosis as I have been carried away with coffee with cream.
I like both camomile and mint tea but at bedtime I drink valerian plus tea for a good night sleep.
