Quality, Sourcing & Product Evidence
SanYuan Herbs treats quality as a recorded relationship between a product, its materials, its batch and the evidence that applies to it.
We separate sourcing records, product specifications, batch traceability, COAs, laboratory reports, first-party tests and market-specific product records instead of hiding everything behind a generic “quality” badge.
Short Answer
How does SanYuan Herbs approach herbal product quality testing? We separate supplier and sourcing records, product specifications, batch/lot traceability, COAs, independent laboratory reports, first-party tests and market-specific product records. A test result is presented only as evidence for the material, product, batch and conditions it actually covers.
What “Quality” Means at SanYuan Herbs
Different questions require different evidence. Identity, specification, traceability, testing, product performance and market readiness should not be collapsed into one generic “premium quality” statement.
Is it the material claimed?
Common name, scientific name when claimed, plant part, material form and formula identity should remain aligned with the product.
What exactly was ordered?
Grade, species, size, formula, physical characteristics and other specifications belong in the record when they matter.
Can it be linked to a supplier and lot?
Supplier, purchase reference, supplier lot, SanYuan lot, product batch and SKU create the chain.
What was actually tested?
Relevant contaminant or microbiological testing should name the sample, scope, issuer, date and result.
Was the property measured?
Low-smoke, warming, wavelength, adhesion, bag integrity or compatibility should be backed by method-specific evidence.
Does the current product match its market record?
Labels, instructions, warnings, specifications and regulatory identity should match the current SKU and target market.
Our Evidence Levels
Not every SKU needs the same evidence depth. The important part is showing what level actually exists instead of presenting every supplier record as if it were a repeated independent laboratory dataset.
Purchase / Supplier Record
Supplier, item/material name, date and purchase/lot reference.
Supplier Specification
Material grade, declared species/part, dimensions, composition or origin where supplied.
Identity / Product Verification
Material identification, formula version, label/BOM match and product image.
COA
Analytical or specification results connected to material, lot, issuer and date.
Independent Laboratory Report
A separate laboratory performs an appropriate analytical or physical test.
Repeated First-Party Dataset
Multiple samples/batches with repeatable methods, photos, results, limitations and review.
Ingredient & Material Sourcing Records
Useful sourcing records should separate material identity, supplier identity, material origin, processing country and the lot references that connect the purchase to a finished product.
Botanical Identity & Formula Control
Common names can refer to several taxa or plant parts. Formula and label control keep the public product identity synchronized with the material and evidence that actually apply.
Useful identity & formula records
FORMULA_VERSION++
→ recheck public ingredient copy
→ recheck label
→ recheck allergen status
→ recheck evidence links
→ recheck product schema
Batch Traceability
Public evidence does not need to reveal confidential pricing or personal data. It should reveal enough linkage to establish which product, batch, report and date belong together.
Testing, COAs & Laboratory Reports
A COA may be issued by a supplier, manufacturer, laboratory or another qualified source. Public evidence should identify who issued it, which lot/batch it covers and what it actually reports.
Report the analytes and measured result
Where relevant, testing may include lead, cadmium, arsenic or mercury. Public evidence should show the actual analytes, units, limits/specifications and result.
Show the panel, method and scope
If a screen is performed, show the sample, defined panel/method, reporting limits where available and the actual result.
Product and market determine the specification
Records may include total counts, yeast/mold or specified pathogens when appropriate. Do not publish one universal limit for every product type.
Not all useful evidence is lab chemistry
Examples include low-smoke incense, warming-patch temperature/adhesion, foot-soak bag integrity, body-oil records and device model measurements.
Allergens & Label Verification
For foods, the current formula, allergen declaration, any supported cross-contact statement and the final market label should be reviewed together.
Current Formula
Use the formula/BOM version that actually applies to the live SKU.
Allergen Declaration
Declare allergens from the current product record and market requirements.
Cross-Contact
Only publish facility or cross-contact statements when supported by supplier/facility evidence.
Gift Sets
Each food component keeps its own allergen information inside a bundle.
Quality by Product Type
Food, incense, external-use products, body oils and devices have different evidence priorities. P023 organizes the framework; SKU pages and evidence libraries own the specific facts.
Herbal Foods & Drinks

Change Control & Recall Readiness
Quality includes knowing when old evidence no longer applies and having records that support correction, withdrawal or recall actions when required.

What should the record system support?
Published Testing & Evidence
P023 is the trust/navigation hub. Individual public COAs, lab reports, first-party tests and evidence records belong in the Testing & Evidence Library.
Evidence Library Framework
Process StandardPublic evidence cards should include Evidence ID, Product/Material, Batch, Evidence Type, Issuer/Lab, Date, Status and Limitations.
Questions to Ask When Reading a Test Report
A generic “Lab Tested” icon gives very little information. Stronger evidence makes the product, batch, sample, method, result, specification and limitations visible.
Frequently Asked Questions
The FAQ avoids universal testing claims and points back to exact product, batch and evidence scope.
How do you test Chinese herbal products?
The test depends on the product and risk. SanYuan Herbs links testing to a specific material, SKU or batch and records the issuer or lab, test scope, date, result and limitations whenever a test is used publicly.
Are all batches tested for heavy metals?
Do not assume a universal panel. The Evidence Library should state exactly which batch was tested and for which analytes.
Are your herbs pesticide-free?
A pesticide test covers a defined method or panel. SanYuan Herbs should publish the actual scope and results rather than use an unlimited “pesticide-free” claim without evidence.
Where do your herbs come from?
Source information is published to the level supported by purchasing and specification records. Supplier location, botanical origin and processing country are treated as separate facts.
What is a COA?
A Certificate of Analysis reports specifications or analytical results for a defined material, product or batch. The issuer and applicable lot should be visible.
Is a supplier COA third-party testing?
No—not automatically. The evidence type should say whether the document came from a supplier, manufacturer or independent laboratory.
How do you handle formula or supplier changes?
Material changes trigger a review of labels, product copy, linked evidence and affected claims before old evidence is reused.
Do you have a recall process?
SanYuan Herbs’ quality data structure should make product and lot records usable for correction or recall actions when required. Market-specific legal procedures depend on product and country.
