What the citation covers
The accepted botanical name with its author, the plant family, the recorded common names, and the distribution. Four facts. That is the whole scope, and every source record in this catalogue states the limit in the same words.
What it does not cover
How the plant is prepared, what it tastes like, how it is graded, which region’s version is considered best, what it is called in a market, or anything about a human body. All of that remains TeaHQ’s own writing with no external source behind it, on all 150 records.
Why the boundary is enforced rather than trusted
An authoritative citation next to an unsupported sentence looks like support for both. Every taxonomy reference in this catalogue is scoped to naming and distribution in the data itself, and a test fails the build if one is ever attached to a whole record.
The correction runs both ways
The authority lists no English common name at all for cardamom, and its only English name for oregano is 'wild marjoram'. That is not a reason to stop using either word. A taxonomic database governs binomials; trade words are a different kind of fact with a different kind of authority behind them.
What is still unsourced
Seventy-seven botanicals have no external citation of any kind, and every page says which it is. The gap is recorded rather than hidden, and it is the largest single piece of outstanding work in the catalogue.
