A coffee enema is a type of colon cleanses used in alternative medicine. 
During the procedure, a mixture of brewed, caffeinated coffee and water is inserted 
into the colon through the rectum. 
Coffee enemas are thought to stimulate bile flow and the production of glutathione, a detoxifying antioxidant.

"咖啡灌肠" 是肠道排毒的一种原始方式，就是利用咖啡的酸性刺激肠壁，促进大肠蠕动，排出宿便解毒，肠毒是万病之源，经常清理肠毒是健康的基本保证 。

【咖啡灌腸10大健康益處】(1) 稀釋肝門靜脈血流，讓膽汁也跟著被稀釋。(2) 茶鹼和可可鹼，也就是咖啡主要的營養保健成分，可讓血管擴張，對抗腸道的發炎反應。(3) 咖啡的棕櫚酸鹽能夠強化GST，而這正是負責移除血清中許多毒性自由基的酵素。(4) 灌腸液本身會刺激內臟神經系統、促進蠕動，以及將稀釋的毒性膽汁從十二指腸輸送到直腸。(5) 由於具刺激性的灌腸液會停留最多１５分鐘，而且體內所有血液大約每３分鐘就會通過肝臟１次，因此咖啡灌腸代表著一種透過腸壁進行血液透析的形式。(6) 減少血清毒素，以去除受損正常細胞（巨分子）的慢性障礙。(7) 改善細胞的鉀離子含量。(8) 減少細胞的鈉含量。(9) 藉由改善水結構而減少細胞腫脹。(10)增加細胞粒腺體的數量和活性，供應細胞產生能量和修復所需的微量營養素。
