Ultrasound Used to Measure the Response of Colonic Motility to Essential Oils
Some essential oils, including peppermint oil (P0) and citral, have been shown to antagonise the ‘in vitro’ stimulation of carbachol on the guinea pig ileum, the magnitude of this effect being directly related to the solubility of the oil(1) Further studies have shown that the same oils reduce spontaneous ‘motility’ of the proximal colon in the intact dog. Also, in patients with Irritable Bowel Syndrome (IBS), PO significantly reduced abdominal symptoms in a double-blind cross over trial(3), while anecdotal reports suggest a use for PO in reducing colon spasm during colonoscopy and in reducing colic during whole bowel irrigation.
