Chimaphila umbellata
Petit sous-arbrisseau toujours vert des forêts nordiques utilisé par de nombreuses tribus amérindiennes pour les affections urinaires, les rhumatismes et les maladies de la peau.
Chimaphila umbellata (pipsissewa) is a small evergreen subshrub traditionally used by Native Americans for urinary tract infections, rheumatism, and skin conditions. Its primary active compounds include the antimicrobial arbutin, the anti-inflammatory triterpenoid ursolic acid, and the naphthoquinone chimaphilin, along with tannins and flavonoids that contribute to its astringent and diuretic properties. Modern evidence is limited (Level C), but it is employed as a urinary antiseptic, anti-inflammatory, and mild diuretic.
Arbutin, a hydroquinone glycoside, is hydrolyzed in the gut to free hydroquinone, which is then conjugated in the liver and excreted in the urine, where it exerts antimicrobial effects against uropathogens. Ursolic acid inhibits cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX), reducing prostaglandin and leukotriene synthesis, thereby providing anti-inflammatory activity. Chimaphilin demonstrates antimicrobial and mild analgesic actions, while tannins precipitate proteins on mucosal surfaces, producing an astringent effect that may reduce inflammation and irritation in the urinary tract. The diuretic action is likely mediated by flavonoids and other phenolic compounds that increase renal blood flow and glomerular filtration rate.
