Will Boiling Water Ruin Green Tea?

A person I know had to get tested for toxins at work regularly and at some point showed really high arsenic levels. At which point they had to figure out what poisoned him. He worked in material science but no materials he handled would have given off arsenic to his body. After some investigating, they found out that the Pu'Erh tea he consumed was the culprit. They tested the tea in a lab and after he stopped drinking it, his levels became normal. So that might not kill.you but I guess having these toxins in you body cannot be good either.

Since then I try to only buy teas which are lab-tested. When I lived in Germany I bought my teas at sunday. Tbey tell you harvest, growing conditions and many more things and they also claim to lab test the tea badges.

I haven't found anything comparable in the US yet.

Boiling isn't going to do anything about arsenic.

Sure, just wanted to add a data point about food poisoning yourself with tea.

Colloquially, "food poisoning" refers exclusively to (per Wikipedia) "Foodborne illness (also foodborne disease and food poisoning); any illness resulting from the spoilage of contaminated food by pathogenic bacteria, viruses, or parasites."

You might want to use water with high level of iron though. My grandfather used to use arsenic to brew cider because its local water had really high levels of iron.

Personally, I wouldn't count on it, see:

Presumably you typo'd the elements here?

Oh wow. Wonder if they tested the same tea at the place he bought it from too.

Just in case... you know... the tea from there didn't have the arsenic in it. (!)

Of course, if he lived by himself that's unlikely to have been a problem. ;)
