chamomile is good for sleep
black tea is good for not sleep
green tea for your appetite (and also improves fertility?)
white tea is uncured and unfermented, good against cancer
oolong tea lowers cholesterol
elderflower tea for the cold
lemon balm tea is good for stress
ginger tea is good for nausea (really really good for nausea)
peppermint tea is for when you feel bloated
hibiscus tea lowers blood pressure (companion to smb)
rooibos tea sounds kinda funny, but there's not much research about it
sage tea is good for brain health
rose hip tea is literally made from a rose, but it helps with inflammation
pu-erh tea (sold in bricks and cakes) supports heart and skin health
I'll add more later (probably)
Also before you make the Bri'ish teeth joke, I was born American and I've never had a cavity in my life
