REHMANNIA GLUTINOSA EXTRACT 10:1 (ROOT)

Rehmannia glutinosa, commonly known as Di Huang in Traditional Chinese Medicine (TCM), is a revered perennial herb native to China. This 10:1 concentrated extract is derived from the plant's root, a part traditionally utilized for centuries due to its profound therapeutic properties. The processing method, often involving steaming and drying, transforms the raw root (Sheng Di Huang) into a potent form (Shu Di Huang) believed to enhance its nourishing qualities. Rehmannia is a cornerstone ingredient in many classic TCM formulas, such as the renowned Liu Wei Di Huang Wan, where it is valued for its ability to 'nourish yin' and 'enrich the blood.' Its distinct sweet and slightly bitter taste reflects its complex phytochemical profile, making it a foundational botanical for holistic wellness applications.

Scientific investigation into Rehmannia glutinosa extract reveals a rich array of bioactive compounds responsible for its diverse health benefits. Key active constituents include iridoid glycosides like catalpol and a series of rehmanniosides (A, B, C, D), along with acteoside and various polysaccharides. Research indicates that catalpol, in particular, exhibits significant neuroprotective effects and plays a role in modulating inflammatory pathways. Rehmanniosides have been studied for their potential impact on glucose metabolism and their antioxidant capacity. These compounds collectively contribute to the extract's traditional uses, supporting kidney and liver health, modulating immune responses, and exhibiting anti-inflammatory activities, thereby promoting overall vitality and systemic balance.

Rehmannia glutinosa 10:1 extract is highly versatile for supplement formulations, commonly found in capsules, tablets, and powdered blends. Its application extends to products targeting kidney and liver support, metabolic balance, blood sugar management, and anti-aging protocols. Quality considerations are paramount, with reputable suppliers often standardizing extracts for key compounds like catalpol to ensure consistent potency and efficacy. Clinical and preclinical studies have explored its benefits, with evidence suggesting its role in mitigating diabetic nephropathy symptoms by improving renal function and reducing proteinuria. Furthermore, its anti-inflammatory properties, attributed to its iridoid glycosides, have been observed in various models, underpinning its use in immune-modulating and inflammatory support formulas. Rehmannia is frequently combined with other synergistic herbs like Goji berry, yam, and cornus fruit to enhance its traditional effects.
