When sourcing rehmanniae powder extract in bulk, the manufacturing facility behind the product matters as much as the extract itself. Cactus Botanics operates a GMP-compliant production ecosystem that spans from raw botanical sourcing through final packaging, giving supplement brands, functional food manufacturers, and cosmetic formulators a reliable supply chain for this traditional botanical ingredient.
What Is Rehmannia Powder Extract?
Rehmannia root extract powder is derived from the tuberous roots of Rehmannia glutinosa, a plant with deep roots in traditional herbal practice. The extract is rich in iridoid glycosides, polysaccharides, and trace minerals, making it a versatile ingredient for dietary supplements, herbal formulations, and functional food products. Cactus Botanics supplies this extract in bulk powder form, processed under controlled conditions to preserve the integrity of its bioactive compounds.
GMP Manufacturing: From Raw Root to Finished Powder
Cactus Botanics maintains GMP-certified production lines that follow standard operating procedures at every stage. The process begins with botanical identity verification of incoming Rehmannia glutinosa raw material. Qualified roots are cleaned, sliced, and dried under controlled temperature and humidity. Where applicable, a traditional processing step involving rice wine infusion is applied to enhance the extract's properties before extraction.
Extraction uses water-ethanol methodology optimized for polysaccharide and iridoid yield. The liquid extract then passes through concentration, purification, spray drying, and sieving to produce a uniform fine powder. Each batch is assigned a unique lot number for full traceability from raw material to finished product.
Quality Control and Testing
Every batch of rehmannia glutinosa extract produced at Cactus Botanics undergoes a comprehensive quality control program. In-house laboratories equipped with HPLC, UV, and GC instruments verify active compound profiles and detect potential contaminants. The testing protocol includes:
- Heavy metal screening (lead, arsenic, cadmium, mercury)
- Microbiological testing including total plate count, yeast, mold, E. coli, Salmonella, and S. aureus
- Loss on drying and ash content analysis
- Identity confirmation via TLC and microscopy
- Residual solvent analysis where applicable
A Certificate of Analysis (COA) accompanies every shipment, and third-party testing is available upon request for clients who require independent verification.
