Saw Palmetto

Serenoa repens

Serenoa repens，通常称为锯棕榈，是一种原产于北美的植物，传统上被土著人用于各种目的。然而，它们在医学中的具体传统用途并未详细记录。科学证据表明，特定的锯棕榈提取物可能改善头发生长参数并减少自认为脱发的成年人的脱发，基于一项系统性回顾。对于良性前列腺增生（BPH），一些研究指出某些配方或联合疗法可能存在潜在益处，但结果变量较大。一项研究表明，在接受锯棕榈提取物治疗的人中，与安慰剂相比，头发数量和脱落显著改善且无不良反应。此外，锯棕榈提取物与阿尔夫唑嗪的组合在降低下尿路症状方面表现出更大的改善效果，从第三个月开始便可见到明显的效果。对于这种植物未记录有重大安全问题或药物相互作用。
