到手香簡介

到手香於台灣民間傳統用藥中,主要用於治療發炎,特別是對於耳炎有很好的療效[1],但目前並未有任何研究文獻針對到手香的可能抗發炎成分進行分析。由於並無研究文獻證實,且使用方式並不正確,因此使用到手香而引起的中毒案例,陸陸續續的在新聞報導中被報導出來。輕微的可能產生過敏現象,最嚴重的案例曾出現多重性器官衰竭,因此在使用上須特別注意安全。

外觀簡述

多年生草本,全株密被粗毛肉質。

枝葉具特殊香氣,葉對生,心形或闊卵形。

穗狀花序,頂生或腋生,小花唇形,淡紫色,萼5枚,雄蕊4,柱頭2裂。

果實

小堅果長卵形。

使用情況

到手香在台灣民間用藥中,主要用於治療耳炎、喉嚨不舒服、外傷[1];治中暑嘔瀉、胸脇苦悶、寒熱頭痛、心腹疼痛、癰腫、疔瘡[2];印尼的傳統用藥則將到手香做為催乳劑,用於哺乳婦女,增加泌乳[3]。

活性研究

  • 1. 泌乳(lactagogue)[3, 9]
  • 2. 抗瘧疾(antimalarial activity):給予感染瘧疾的albino小鼠到手香水萃取物,250及500 mg/ml在24、48、72及96小時都有顯著的降低瘧原蟲量。相較現用的藥物chloroquine,250及500 mg/ml的藥物抑制率分別為67.9%及76.2%[10]。

毒性研究

  • 症狀
    • 皮膚紅疹、全身發養、水泡性紅腫並脫皮、結膜炎、口腔潰瘍並出血、解尿困難,合併出現膽妄症及肝功能異常等多重器官衰竭。

  • 有毒成分

1. carvacrol[11, 12] 2. tthymol[12]

  • 中毒劑量
    • 未知

  • 機轉
    • 未知

  • 基因毒性
  • 1. ECarvacrol (10, 30, 50及70 mg/kg b.w., 6h, 12h及24h)顯著提高結構染色體(structural chromosome)及總染色體(total chromosome);Carvacrol (50及70 mg/kg b.w., 24h)同時也導致numerical chromosome aberrations顯著上升;Carvacrol (70 mg/kg b.w., 6h; 50, 70 mg/kg b.w., 12h)也表現出與urethane (400 mg/kg b.w.)相類似的降低mitotic index (MI)的能力。Thymol引起結構染色體(80, 100 mg/kg b.w., 6h; 100 mg/kg, 12h)、總染色體(60, 80及100 mg/kg b.w., 6h; 100mg/kg b.w., 12h和24h)及numerical chromosome aberrations (40, 80及100 mg/kg b.w., 6h和12h; 80, 100 mg/kg b.w., 24h)顯著異常。Thymol (60, 80及100 mg/kg b.w., 6h; 40, 60, 80及100 mg/kg b.w., 24h)相較urethane顯著降低MI[11]。
  • 2. Ccarvacrol (0.1 microM)及thymol (0.1 microM)以Aems試驗測試基因毒性,結果顯示經代謝後的給藥組相較控制組,回復率提高1.5-1.7倍,但並無顯著差異[12]。
