垂钓、郊游、远足这些活动多在城外,不便携带足够的饮用水。我有个防止口渴的方法。还是从“望梅止渴”的典故受到启发,联想到生姜有辛辣的性能,于是用刀切一片厚度约3毫米的生姜,垂钓时始终含在嘴里,不嚼碎。实践证明,口中含姜后口腔唾液增多,咽喉清润,不仅止渴效果好,且对防病治病增强健康有好处。 Fishing, hiking, hiking These activities are outside the city, inconvenient to bring enough drinking water. I have a way to prevent thirst. Inspired by the story of Wang Mei Zhi Thirst, I learned that the ginger has spicy properties. I then cut a piece of ginger about 3 mm thick with a knife and kept it in my mouth when fishing, without chewing. Practice has proved that mouth with ginger oral saliva increased, throat Qingrun, not only good effect of thirst, and disease prevention and treatment to enhance health is good.
