64+ Peer-Reviewed Citations

Medical Sources

Every claim Pureami Tea Company makes is grounded in published, peer-reviewed medical literature. Below are the sources — all available free at PubMed.com.

Our Commitment to Transparency

The three names — Myricetin, DiHydroMyricetin, and Ampelopsin — all refer to the same flavonol. Search any of them on PubMed.com and you will find a substantial body of evidence. Qing Yun Moyeam produces this compound at 30–40% by plant weight, versus 3–6% for ordinary grades.

We do not cherry-pick studies. We have never made a claim not supported by the published literature. All citations below link directly to their source on PubMed or the original journal.
