耳鳴、蟬鳴聲

《虛證—蟬鳴聲型耳鳴》

若耳鳴聲屬於「蟬鳴聲」，則應與年老精衰、腎元虧乏，以致耳竅失養，發為耳鳴、耳聾有關。中醫典籍《靈樞經•脈度》中就提到，「腎氣通於耳，腎和則耳能聞五音矣」之說，以及「髓海不足則腦轉耳鳴」的紀錄。

治療方針：所以調理上，會以滋補腎陰、益氣活血為主。

推薦茶飲：

★核桃黑米粥

材料：核桃仁7顆、黑豆5公克、黑芝麻5公克、黑米5公克、白米5公克、枸杞20顆、山藥2片。

做法：製作前一天先把食材用冷水泡軟，第二天加入適量的水熬粥，以中火熬煮大概15分鐘，至水變黏稠的時候關火，用蓋子悶1小時後就可以使用。

作用：核桃、黑豆、黑芝麻、黑米、枸杞、山藥等食材有滋陰補腎、益氣活血的作用，適合年老精衰、腎元虧乏的耳鳴患者食用。

減緩耳鳴發作這樣做！時刻揉按4穴位，自我保健不求人

除了針對造成耳鳴發生的2大類型加以解說，郭祐睿中醫師也推薦經常有耳鳴困擾民眾，不妨可以養成時時扣擊耳門、聽宮、聽會及翳風4個保健穴位的習慣，每次搓揉1分鐘，到有酸脹感為止，就是很好的居家自我保養方式：

★聽宮穴：位於面部、耳屏前，下頜骨髁狀突的後方，張口時呈凹陷處。主治耳鳴、耳聾。

★耳門穴：位於頭部側面耳前，耳珠上方稍前的缺口，在聽宮穴上0.5寸，是治療多種耳疾重要的首選穴位之一。

★聽會穴：位於面部，在聽宮下方，張口有凹陷處。《百症賦》中「耳聾氣閉、全憑聽會、翳風」的記載，也是治療耳鳴的重要穴道。

★翳風穴：位於耳垂1後方，當乳突與下頜角之間的凹陷處。《扁鵲神應針灸玉龍經》日：「若人患耳即成聾，下手先須覓翳風。」所以搭配耳門、聽宮、聽會，四穴一體按摩，適度刺激能輔助改善耳鳴現象。
