Liquorice Versus Sugar-Water Gargle for Prevention of Sore Throat
Licorice may reduces the risk of post-operative sore throat according to recent studies by a team of scientists based at the Vienna Medical University (Ruetzler et al).
The investigation tested the hypothesis that pre-operative gargling with liquorice solution prevents postoperative sore throat and post-extubation coughing in patients intubated with double-lumen tubes.
A Randomized, Double-Blind Comparison of Licorice Versus Sugar-Water Gargle was evaluated.
Data suggests that the incidence of postoperative sore throat was significantly reduced in patients who gargled with licorice rather than sugar-water: 1
The study concludes that licorice gargling halved the incidence of sore throat. Pre-induction gargling with licorice appears to be a simple way to prevent a common and bothersome complication.
