>>23498911they are just getting sick from matcha or they get the ground up shit in teabags and brew it for too long.
I drink green tea most mornings on an empty stomach and its never made me nauseous.
black tea often causes vomiting when consumed on an empty stomach because of the tannins and the same thing can happen with Matcha or improperly brewed or cheap green tea.
green tea is pretty low in tannins but Matcha is powdered so you are basically consuming the leaves along with the extraction meaning you absorb all of the tannins present in the leaf.
this is compounded by the fact that caffeine is an emetic at high doses so drinking too much of anything containing it can make you puke.
properly brewed loose leaf green tea should have practically zero tannins released into the water but the shit in teabags is made from the cheapest floor sweepings the company can get which have more tannins and its also ground up which will cause more of the them and the caffine to be diffused into the water when brewing leading to higher chances of it making you feel sick or spew.
