## Top 5 Reasons Buyers Choose Our Astragalus
1. **Geo-authentic Dingxi origin** — Dingxi is documented in the Chinese
Pharmacopoeia as a primary geo-authentic (“dao di”) origin for
*Astragalus membranaceus*. We source directly from contracted growers
in Dingxi at altitudes of 1,800-2,400 meters.
2. **HPLC-verified Astragaloside IV content** — Each production batch is
tested via HPLC for Astragaloside IV content. Standard grade meets
Chinese Pharmacopoeia 2020 (≥ 0.04%); premium grade available on request
(≥ 0.08%).
3. **Sulfur-free option for regulated markets** — Standard processing keeps
SO₂ residue below 30 ppm. Our optional sulfur-free workflow uses ambient
drying and is suitable for EU and US supplement-grade applications.
4. **Manufactured at a US FDA-registered facility** — Our facility maintains
FDA registration under 21 U.S.C. 350d, with China Food Safety GMP
(GB 14881), ISO 22000, and CQC-HACCP certifications.
5. **Tiered MOQ supports brand development** — From 1 kg samples for
R&D teams to 500 kg+ production runs and full container loads (2-20 tons)
for established brands.
## Geo-Authentic Origin: Why Dingxi, Gansu
Dingxi sits on the northeastern edge of the Tibetan Plateau in central
Gansu Province. The combination of high altitude (1,800-2,400 m),
calcium-rich loess soil, large diurnal temperature variation, and
semi-arid climate produces *Astragalus membranaceus* roots with
characteristic structural density and high marker compound content.
The Chinese Pharmacopoeia documents Dingxi as one of the primary
geo-authentic (“dao di yao cai”) regions for Astragalus. Local farming
cooperatives in Anding District, Longxi, and Weiyuan counties have
cultivated this species for generations, with harvest timing in
autumn (October-November) when the root reserves of polysaccharides
and saponins are at their seasonal peak.
We maintain procurement agreements with selected cooperatives in this
region, allowing batch-level traceability from field to finished product.
## Manufacturing & Quality Control
Production at our Pingliang facility follows a 15-step workflow:
1. Raw material inspection and origin verification
2. Cleaning (removal of soil and foreign matter)
3. Sorting by diameter and quality grade
4. Moistening (humidity-controlled softening)
5. Slicing (2-3mm standard, or custom thickness)
6. Initial drying (low-temperature, ambient airflow)
7. Final drying (controlled humidity to ≤ 12%)
8. Sifting and removal of fines
9. Visual inspection
10. Sampling for laboratory testing
11. Astragaloside IV content verification (HPLC)
12. Pesticide and heavy metals testing
13. Microbial limits testing
14. Final packaging in food-contact compliant materials
15. Pre-shipment quality inspection
Our 12-member QC team conducts testing in a CNAS-affiliated laboratory
representing ¥9 million in equipment investment, including GC-MS for
pesticide analysis and ICP-MS for heavy metals quantification.
## Testing & Compliance Documentation
Each shipment includes:
– **Certificate of Analysis (COA)** — botanical identity, moisture,
active compound content, microbial limits
– **Pesticide Residue Report** — GC-MS analysis covering 50+ pesticide
compounds against USP <561>, EU 396/2005, and ChP standards
– **Heavy Metals Report** — Pb, Cd, As, Hg, and optional extended panel
– **Microbial Limits Report** — TPC, yeast/mold, *E. coli*, *Salmonella*
– **Phytosanitary Certificate** — issued by Chinese inspection authorities
– **Certificate of Origin** — from China Council for the Promotion of
International Trade (CCPIT)
– **Sulfur Dioxide Residue Report** — for sulfur-free shipments
– **Packing List and Bill of Lading**
– **Optional: Pesticide testing to specific buyer-requested panels**
## Industry Applications
Astragalus root slices are used as raw material in:
– Dietary supplement formulations — capsules, tablets, powders, tinctures
– Functional beverage and herbal tea products
– Traditional Chinese Medicine clinical prescriptions and patent formulas
– Cosmetic botanical extracts (skincare formulations)
– Pet supplement raw materials
– Herbal extract powder bases for further processing
## Packaging & Export Options
| Format | Capacity | Use Case |
|——–|———-|———-|
| PP woven bag (standard) | 25 kg | Container load, palletized export |
| Food-contact compliant HDPE drums (21 CFR 177.1520) | 50 / 100 / 200 kg | High￾protection bulk shipment |
| Vacuum-packed cartons | Custom | Retail-ready, private label |
| Branded private-label bags | Custom | OEM brand owners |
| FBA-prep cartons | Custom | Amazon FBA direct preparation |
All packaging materials are food-contact compliant. We do not use
“FDA-approved” labeling because FDA does not approve packaging materials
in the same way it approves drugs; instead, we ensure compliance with
applicable food-contact substance regulations (21 CFR 174-186).

## Frequently Asked Questions
### What’s the difference between Astragalus (Huang Qi) and Hedysarum (Hong Qi)?
Astragalus (*Astragalus membranaceus*) and Hedysarum (*Hedysarum polybotrys*,
called “Hong Qi” or “Red Astragalus”) are two distinct botanical species
often confused in trade. Both appear in the Chinese Pharmacopoeia under
separate monographs and should not be substituted without proper labeling.
Astragalus has wider international recognition; Hedysarum is geo-authentic
to Gansu Province with limited supply outside this region.
### Can you provide sulfur-free Astragalus?
Yes. Our sulfur-free Astragalus uses ambient drying without sulfur dioxide
fumigation, maintaining SO₂ residue below 30 ppm — well within EU and US
import limits for dietary supplement raw materials. A separate sulfur dioxide
residue report is issued for each sulfur-free shipment alongside the standard
COA.
### What is the typical Astragaloside IV content?
Standard-grade Astragalus root slices contain Astragaloside IV at ≥ 0.04%
measured by HPLC, meeting Chinese Pharmacopoeia 2020 requirements.
Premium-grade lots reach ≥ 0.08% and are available with batch-specific
documentation. Content can vary with harvest year, region, and processing;
we provide per-batch test data on request.
### Do you ship to the United States and European Union?
Yes. Our facility maintains US FDA registration, and we have shipped to
North American supplement brands consistently since 2018. For EU shipments,
we provide phytosanitary certificates, heavy metals and pesticide residue
reports compliant with EU Regulation 396/2005, and country-specific
documentation as required.
### How is Astragalus traditionally used?
In Traditional Chinese Medicine, Astragalus root is one of the most
commonly referenced tonic herbs and appears in numerous classical formulas.
Modern applications include use as a raw material in dietary supplements,
functional foods, and herbal tea products. We do not make health claims;
end-product formulators are responsible for applicable regulatory compliance
in their target markets.
