Recently, in the field of natural herbal health and the functional food ingredient market, Couch Grass Extract Powder (scientific name: Elymus repens extract)—an extract derived from traditional medicinal plants—has continued to be the focus of attention in the health industry and herbal raw material sector, thanks to its natural effects in maintaining urinary health and relieving inflammation, as well as its characteristics of "safety, mildness, and easy compounding". As a "urinary-regulating herb" used for thousands of years in traditional medicine in Europe and Asia, Couch Grass Extract Powder not only inherits the natural advantages of botanical medicines but also retains core active ingredients through modern extraction processes. It plays a unique role in urinary health products, herbal dietary supplements, and mild skincare products, providing plant-derived solutions for consumers pursuing natural health.
Its core active ingredients include triterpenoid saponins (e.g., Elymoside A, B), polysaccharides, flavonoids, and volatile essential oils. Among them, triterpenoid saponins are the key substances for exerting urinary-regulating and anti-inflammatory effects, while polysaccharides provide mild mucosal protection and auxiliary immune regulation for the extract. Verified by modern pharmacological research and traditional applications, relying on its three core advantages of "urinary regulation, anti-inflammatory soothing, and mucosal protection", Couch Grass Extract Powder has demonstrated clear efficacy in three major fields—urinary health maintenance, herbal anti-inflammatory care, and mild skin soothing—becoming a "characteristic functional ingredient" among natural herbal raw materials.
In the field of urinary health, the core efficacy of Couch Grass Extract Powder stems from its dual effects of "diuresis" and "assisting in stone dissolution", a characteristic that highly aligns with the application wisdom of "promoting water circulation" in traditional medicine. Modern studies have shown that the triterpenoid saponins it contains can support urinary health through two mechanisms: On one hand, it can gently promote the production and excretion of urine in the kidneys (diuretic effect), increasing urine volume while diluting the concentration of crystalline substances (e.g., calcium oxalate, urate) in urine, thereby reducing the risk of crystal deposition and stone formation. On the other hand, triterpenoid saponins can bind to tiny stone particles in urine, reducing the adhesion between particles, assisting in the excretion of tiny stones with urine, and at the same time reducing the frictional irritation of stones on the urinary tract mucosa, alleviating urinary discomfort (e.g., painful urination, frequent urination, incomplete emptying of the bladder).
Clinical observation data shows that daily intake of dietary supplements containing 500-1000mg of standardized Couch Grass Extract Powder for 4-8 weeks can help people with mild urinary discomfort (e.g., poor urination due to prolonged sitting, seasonal urine concentration) increase urination frequency (an average increase of 1-2 times per day) and reduce urine osmolarity. Meanwhile, the urinary discomfort score (e.g., stinging, burning sensation) of the subjects decreased by 30%-40%. Currently, many European herbal health brands have used it as a core ingredient in products such as "urinary health capsules" and "herbal diuretic tea bags", which are particularly suitable for people who sit for a long time, middle-aged and elderly people, and consumers who need daily maintenance of urinary health.
The anti-inflammatory effect of Couch Grass Extract Powder is not only applicable to the urinary system but also demonstrates mild advantages in the care of mucosal and soft tissue inflammation. Its active ingredients—triterpenoid saponins and flavonoids—can inhibit the release of inflammatory factors (e.g., TNF-α, IL-6) in the body and reduce the accumulation of inflammatory cells (e.g., neutrophils) at the inflammatory site, thereby alleviating local redness, pain, and burning sensation. In traditional applications, couch grass extract is often used to relieve inflammation of the throat mucosa (e.g., sore throat, dry throat) and mild discomfort of the gastrointestinal mucosa (e.g., post-meal bloating, mucosal irritation). In vitro experiments show that a 10% concentration of Couch Grass Extract can inhibit the inflammatory factor IL-6 by 28%-35% without cytotoxicity, proving that its anti-inflammatory effect is mild and safe.
In the field of mild skincare, relying on the mucosal protection effect of its polysaccharide components and anti-inflammatory properties, Couch Grass Extract Powder has become a "natural auxiliary ingredient" in skincare products for sensitive and damaged skin. The polysaccharides it contains can form a thin moisturizing protective film on the skin surface, reducing transepidermal water loss (tests show that lotion containing 2%-3% of the extract can increase the moisture content of the skin's stratum corneum by 15%-20%), while alleviating damage to the skin barrier caused by external stimuli (e.g., ultraviolet rays, dry environment, skincare product ingredients). Triterpenoid saponins, on the other hand, relieve common discomforts of sensitive skin such as redness, burning, and itching by inhibiting local inflammatory reactions of the skin. Compared with traditional chemical soothing ingredients (e.g., allantoin, panthenol), Couch Grass Extract Powder combines three functions: moisturizing, anti-inflammatory, and barrier protection. Moreover, as a plant-derived ingredient, it is more in line with the "Clean Beauty" consumption trend and is favored by people with sensitive skin and natural skincare brands.
