Flavone that modulates mast-cell activation, microglial signaling, and inflammatory cascades including NF-kB activity.
Saw palmetto berry extract contains fatty acids (lauric acid, oleic acid, myristic acid) and phytosterols (beta-sitosterol) that inhibit both isoforms of 5-alpha-reductase (types I and II), reducing conversion of testosterone to dihydrotestosterone (DHT). It also exhibits anti-androgenic activity by competing with DHT at androgen receptor binding sites. Additional mechanisms include: inhibition of cyclooxygenase and 5-lipoxygenase (anti-inflammatory in prostate tissue), induction of apoptosis in prostate epithelial cells, and relaxation of bladder smooth muscle via alpha-1 adrenergic receptor antagonism.
