藥用價值:
此屬植物多數品種葉片含草酸,葉具檸檬香氣,可少量食用,在可鎖定大量草酸的營養鹽中不可大量食用其葉,特別是鈣鹽,易導致礦物質缺乏症,煮熟後會降解其所含草酸。具有內風濕、關節炎、痛風、腎結石、胃酸過多症傾向的人群食用會加重其病症需謹慎。
補充:根是澀的,用作輸液對治療出血有好處,根在早春收貨並風乾待用。用葉子做成的湯可以治療一些皮膚病。{來自維基百科}(原文如下)The root is astringent. An infusion is useful in the treatment of bleeding. The root is harvested in early spring and dried for later use. A decoction of the leaves is used in the treatment of several skin diseases.
