Product Description
Reliable Astragalus Root Powder Manufacturer & Bulk Supplier
Greenherb operates a GMP-certified processing facility specializing in Astragalus Root Powder. We source raw roots from certified cultivation bases practicing sustainable agriculture to minimize environmental impact. Our low-temperature dehydration and cryogenic milling process preserves heat-sensitive polysaccharides and saponins without oxidation. We provide full export documentation and technical support for seamless integration into your supply chain.
Why Choose Greenherb Astragalus Root Powder
- Polysaccharide Preservation – We utilize a proprietary low-temperature concentration process that preserves the native polysaccharide structure, ensuring our astragalus root extract delivers consistent functional value.
- Solvent-Free Processing – Unlike liquid extracts, our powder is produced via physical dehydration and mechanical micronization, leaving zero solvent residues and meeting clean-label standards.
- pH-Stable Saponin Profile – Our process stabilizes the natural triterpene saponins, preventing the rapid degradation typically seen in astragalus products exposed to heat and light.
- Microbiological Control – Low-temperature drying (<50°C) reduces water activity to inhibit microbial growth, extending shelf life without irradiation.
- Particle Size Engineering – We offer customized mesh sizes (80 to 300 mesh) to optimize flowability for tablet pressing or instant dispersion in beverages.
- Oxidative Stability – Nitrogen-flushed packaging prevents the oxidation of sensitive phenolic compounds during storage and transit.
- Export Documentation Support – Shipments include COA, MSDS, Organic Certificate, and Non-GMO affidavit to facilitate customs clearance.
- Logistics Coordination – We work with specialized freight forwarders experienced in handling root powders, ensuring moisture-proof delivery.
- Direct Factory Pricing – Eliminate distributor markups with transparent pricing for bulk quantities and long-term supply agreements.

Product Introduction
Astragalus Root Powder is a traditional medicinal ingredient derived from the dried roots of Astragalus membranaceus. By utilizing a physical grinding process rather than chemical extraction, we retain the full spectrum of water-soluble polysaccharides, saponins, and dietary fiber. This astragalus root supplement serves as a functional food ingredient, offering a concentrated source of immunomodulatory compounds. It is designed for formulators seeking a clean-label ingredient with high phytonutrient density for food, beverage, and supplement applications.
Production Process
Greenherb employs a controlled physical processing sequence:
-
Root Authentication – Harvesting of 4-year-old roots, followed by macroscopic and TLC identification to confirm species integrity.
-
Washing & Sanitization – High-pressure air and water cleaning to remove soil and surface contaminants without leaching soluble nutrients.
-
Low-Temp Dehydration – Belt drying at controlled temperatures (<50°C) to remove moisture while preserving heat-sensitive compounds.
-
Cryogenic Grinding – Milling under liquid nitrogen atmosphere to achieve ultra-fine particles without heat damage.
-
Sieving & Blending – Classification by mesh size and homogeneous blending for batch consistency.
-
Laboratory Testing – QC verification of microbial load, heavy metals, and nutrient markers.
-
Secure Packaging – Double-layer PE bags with desiccants, sealed within fiber drums.
