Rehmannia extract, derived from the root of Rehmannia glutinosa, has become one of the most sought-after botanical ingredients in the global nutraceutical and pharmaceutical industries. With the global rehmannia extract market valued at over USD 312 million in 2025 and projected to grow at a steady pace through 2032, demand from supplement manufacturers, functional food developers, and traditional medicine formulators continues to rise. If you are sourcing this ingredient in bulk, finding a reliable wholesale supplier is essential to ensuring consistent quality, competitive pricing, and regulatory compliance.
What Is Rehmannia Extract?
Rehmannia glutinosa is a perennial herb native to China and has been a cornerstone of Traditional Chinese Medicine (TCM) for centuries. The root is processed into extracts — most commonly in powder form — that are rich in bioactive compounds such as catalpol and other iridoid glycosides. These compounds are associated with a range of health-supporting properties, including adrenal support, blood sugar regulation, and anti-inflammatory effects. In recent years, rehmannia extract has also gained traction in skincare formulations for its moisturizing and skin-repairing benefits.
The extract is typically available in standardized ratios such as 5:1, 10:1, or 20:1, and can be specified by active marker content such as catalpol percentage. The powder format dominates the market, accounting for nearly 69% of global sales, due to its versatility in capsules, tablets, powdered beverages, and functional food blends.
Who Sells Rehmannia Extract Wholesale?
The global supply chain for rehmannia extract is largely concentrated in China, where the raw herb is cultivated and processed. Numerous manufacturers in Shaanxi, Xi'an, and other provinces offer wholesale quantities. However, quality and reliability vary significantly among suppliers. For international buyers — particularly those in North America, Europe, and emerging markets — working with a supplier that combines manufacturing capability with global logistics, quality certifications, and local warehousing is a strategic advantage. This is where Cactus Botanics stands out.

- Manufacturing Location and Capacity: Does the supplier have direct manufacturing control, or are they a trading intermediary? Direct manufacturers typically offer better pricing and quality consistency.
- Certifications: Look for GMP, ISO, organic, and other relevant certifications that align with your target market's regulatory requirements.
- Testing and Documentation: Ensure the supplier provides comprehensive certificates of analysis (COA), including active compound content, heavy metals, and microbiological data.
- Supply Chain Stability: A supplier with multiple sourcing and production locations can better manage raw material price fluctuations and supply disruptions.
- Logistics and Support: International shipping experience, warehousing options, and responsive customer service are critical for smooth procurement.
