【应用】        1.肾虚腰痛、阳痿遗精、尿频及宫冷不孕。本品辛以润燥,甘以补虚,为平补阴阳之品,功能补肾阳、益肾精以固精缩尿。如菟丝子、炒杜仲等分,合山药为丸,治腰痛(《百一选方》);与枸杞子、覆盆子、车前子同用,治阳痿遗精,如五子衍宗丸(《丹溪心法》);与桑螵蛸、肉苁蓉、鹿茸等同用,治小便过多或失禁,如菟丝子丸(《世医得效方》);与茯苓、石莲子同用,治遗精、白浊、尿有余沥,如茯苓丸(《和剂局方》)。

【古籍摘要】        1.《神农本草经》:“主续绝伤,补不足,益气力肥健。”“久服明目,轻身延年。”       
 
2.《本草经疏》:“五味之中,惟辛通四气,复兼四味,《经》曰肾苦燥,急食辛以润之。菟丝子之属是也,与辛香燥热之辛,迥乎不同矣,学者不以辞害义可也。”       
 
3.《本经逢原》:“菟丝子,祛风明目,肝肾气分也。其性味辛温质粘,与杜仲之壮筋暖腰膝无异。其功专于益精髓,坚筋骨,止遗泄,主茎寒精出,溺有余沥,去膝胫酸软,老人肝肾气虚,腰痛膝冷,合补骨脂、杜仲用之,诸筋膜皆属之肝也。气虚瞳子无神者,以麦门冬佐之,蜜丸服,效。凡阳强不痿,大便燥结,小水赤涩者勿用,以其性偏助阳也。”
