I've been a tea fan for many years, and even I learned new things from this zine! So cool. I always thought it was enough to just boil the water, not knowing it could work better if it got hotter! Exciting stuff, I'll try some things out!
Less hot! Less hot than boiling water! I'm sorry if I made this unclear, but the temperatures I gave should be all way below boiling water (which is at 100°C and 212°F afaik). The only time when I recommend boiling the plant is when making tea from plants you've gathered yourself, but that's for another zine.
