A reading room for Chinese tea and what the evidence actually says
You heard a claim about Chinese tea and health — green tea for blood pressure, pu-erh for cholesterol — and want the honest answer before you believe it. tea.doctor pairs each traditional benefit with peer-reviewed research — catechins, L-theanine, theabrownins, caffeine kinetics. We do not prescribe. We translate, cite, and let you read the studies yourself.

Theabrownins (aged tea)
Aged sheng and serum lipids — a measured look at the 2019 paper
Shēng Pǔ'ěr · 生普洱
A Shanghai–Hong Kong research team — often mis-credited to “Kunming Medical University” in tea-shop retellings — reported that theabrownins extracted from pu'er lowered cholesterol in mice, and ran a small human pilot besides. The paper travelled far, sometimes further than the data supports. Here is what it measured, what it did not, and how aged sheng fits into the picture.
Tea and sleep
Aged tea as an evening routine — what the small studies show
lǎo chá · 老茶
Aged tea — be it a dark, brothy shou pu'er or a mellow, decade-old white tea — has quietly become the anchor of many evening rituals. But how does it sit with sleep? We sift through small-scale studies, chemical transformations, and traditional wisdom to see what can be said and what remains a quiet question.
Catechins and EGCG
EGCG bioavailability — what's measured in human plasma
Chá Duō Fēn · 茶多酚
What researchers actually find in blood after a cup of green tea — and why 200 mg of EGCG in the cup doesn’t equal 200 mg in plasma.
