Pseudostellaria heterophylla is widely listed on B2B marketplaces, but listings vary enormously in quality and honesty. This roadmap condenses what an international buyer actually needs to do to source dried Tai Zi Shen root reliably from China.

1. Shortlist by origin, not by price

Start with suppliers who can state a specific growing origin — down to the county — and show evidence of it. Origin-first shortlisting removes most of the risk before price is even discussed.

2. Verify the botanical identity

Confirm in writing that the material is Pseudostellaria heterophylla (Miq.) Pax, dried root tuber. This excludes Panax ginseng and Codonopsis pilosula confusions at the contract level.

3. Ask for a sample before anything else

A sample tells you more than any listing: root integrity, colour, cleanliness, odour and moisture feel. Evaluate samples side by side from several suppliers and keep reference samples for future lot comparison. You can request a sample from us with your enquiry.

4. Define your specification

Put your requirements in writing: botanical identity, form, grade/sorting level, foreign matter tolerance, moisture target, packaging and testing scope. A serious supplier will respond with what they can document per batch — not with invented round numbers.

5. Check the documentation chain

Ask which documents come with a shipment: COA, botanical identification, origin documentation. Our guide to checking a COA walks through the test items that matter for dried roots.

6. Start with a measured first order

First orders are about validating the chain — sample, documents, shipment condition — more than optimising price. Once a lot arrives matching the approved sample and COA, scale with confidence.

Red flags: no verifiable origin, no sample policy, specification sheets with suspiciously perfect numbers, and “ginseng” listings that avoid the botanical name.

We follow exactly this process with our own buyers: origin evidence first, samples and batch documentation second, pricing third. Start with the product page or send us your requirements directly.
