At the heart of our product lies Dendrobium nobile stem extract, also known as Shi Hu in traditional Chinese medicine or noble dendrobium extract. Sourced from the resilient stems of the orchid species Dendrobium nobile, this botanical ingredient has been celebrated for centuries in herbal practices for its adaptogenic and rejuvenating properties. What sets it apart are its unique bioactive compounds, particularly dendrobine alkaloids, which are regarded as the primary active constituents.
These alkaloids, along with polysaccharides and glycoproteins, contribute to the extract's potential to support vitality, balance, and overall wellness. In today's market, interest in Dendrobium nobile extracts is steadily rising, fueled by growing consumer demand for natural, plant-based health supplements. However, many available options lack transparency in sourcing or standardized active compounds, creating an opportunity for a more refined, high-quality solution.
Our approach begins at the origin—using sustainably harvested Dendrobium nobile stems, processed with gentle extraction methods to preserve delicate alkaloids like dendrobine. What truly sets us apart, however, is our OEM expertise tailored to botanicals with complex compositions. While many suppliers treat herbal extracts generically, we've developed specialized techniques to standardize dendrobine content without degrading synergistic compounds—ensuring every batch delivers both potency and consistency. Combined with our flexible OEM services—from custom formulation to branded packaging—we help our partners offer a premium, science-backed Dendrobium extract that stands out in a crowded marketplace.
We guarantee a minimum of 8% total dendrobine alkaloids through our proprietary low-temperature ethanol-water extraction technology. This ensures your finished products deliver reliable, clinically-relevant bioactivity.
We eliminate raw material variability by sourcing directly from GAP (Good Agricultural Practices)-certified farms in Yunnan. We cultivate specific cultivars selected for high alkaloid yield (typically >0.03% in raw stems), providing full traceability and safeguarding against contamination.
Integrating two decades of R&D into your custom formula. We offer custom ratios (e.g., 10:1 or 20:1) and carrier agents (like maltodextrin or silica) tailored to your capsule, tablet, or liquid formulation needs.
