Product Description
Food Grade Free Sample Pure Rehmannia Extract
Introduction:
Rehmannia Extract is derived from the root of Rehmannia glutinosa, a perennial herb native to China and East Asia, where it has been a cornerstone of traditional herbal medicine for centuries. Known as Dihuang in Chinese medicine, this adaptogenic root contains a unique profile of iridoid glycosides (such as catalpol and rehmannioside), phenethyl alcohol derivatives, and oligosaccharides that contribute to its multifaceted therapeutic properties. Unlike many botanicals, Rehmannia undergoes specific processing methods (raw or steamed) that significantly alter its bioactive composition and clinical applications. Modern research has validated its traditional use for supporting adrenal function, blood health, and kidney vitality, with emerging evidence highlighting its immunomodulatory and anti-aging potential through activation of the Nrf2 antioxidant pathway. The extract's ability to modulate both Yin deficiency patterns in traditional medicine and oxidative stress markers in contemporary research makes it a rare bridge between ancient wisdom and modern science.

Applications of Rehmannia Extract
Rehmannia Extract is extensively formulated in adrenal support and stress resilience supplements, where its adaptogenic compounds help regulate cortisol rhythms and HPA axis function. The nutraceutical industry incorporates processed (steamed) Rehmannia into blood tonic formulations targeting healthy iron metabolism and circulation, particularly in women's health products. Its nephroprotective properties make it a key ingredient in kidney health supplements, often combined with astragalus and poria in traditional synergistic formulas. Emerging applications include longevity supplements, where its oligosaccharides demonstrate senotherapeutic potential by reducing cellular senescence markers. The cosmetic industry utilizes raw Rehmannia extract in anti-aging serums for its ability to enhance skin hydration and reduce glycation end-products. Traditional Chinese medicine clinics continue to prescribe customized Rehmannia formulations for managing heat/fluid imbalance patterns, while modern functional medicine practitioners employ standardized extracts for metabolic and immune support. As research progresses on its epigenetic modulation effects, Rehmannia is gaining recognition beyond traditional markets, though quality standardization remains essential due to significant variations in processing methods and bioactive content across commercial extracts.
