Most Chinese orris reaches Europe
through two or three intermediaries, and the field it came from is rarely named. We are trying
the opposite: one named block, a batch log that a buyer can read, and analytical results
published as they are produced — including the batches that disappoint.

Three things you can check
A field with an address
Yaozhou District, Tongchuan, Shaanxi. Semi-arid loess, deep and free-draining, at
800–1,000 m. Not a trading desk — a block you can visit, photograph, and sample.
Low-input by rule, not by claim
Zero artificial irrigation. Zero post-emergence herbicide. Fermented sheep manure as
the only basal nutrition. All three are written into the SOP and appear in the batch log
you receive.
Supervised, and honest about the limits of that
Field protocol and analytical method are reviewed with the Aromatic Iris Research Group
at Xi’an Botanical Garden (Shaanxi Institute of Botany). That is a technical collaboration,
not a certification — and we will not describe it as one.

Download the documents, not the brochure
Three files, sent to your work email. No newsletter,
no list, no follow-up sequence.
- Technical data sheet (PDF) — full specification, analytical method, packaging and export documentation.
- GACP batch log, redacted example — what actually arrives with a lot, before you ask for it.
- COA template (PDF) — the certificate format we issue.
We use your address to send these files and to answer you. Nothing else.
Publishing from this block
We write about the parts of orris supply that are
usually left unsaid: why the crop is permanently short, what soft rot costs a grower, and how
to read a COA. Six pieces are in draft; the first publishes in Q4 2026.
- Why orris is always short: the three-year cycle, by the numbers
- Rain-fed vs irrigated orris: what soft rot actually costs a grower
- Reading a COA for orris root: five numbers that matter
- ISO 18054 is written for oil, not root — and why your QC should care
- Loess vs Tuscany: two soils, two irone profiles
- What a GACP batch log actually looks like
