How can salt be used in the following cases? Problem Use of common salt In your toothache One day when you suffered suddenly from vomiting and diarrhoea In your throat pain A leech bites in your leg Preservation of ripe tamarind If a symptom like low blood pressure is found in someone

Salt water is a natural disinfectant, and it can help loosen food particles and debris that may be stuck in between your teeth. Treating a toothache with salt water can also help reduce inflammation and heal any oral wounds. To overcome from vomiting and diarrhoea, we must take a small amount of solution made from a little salt and sugar at regular intervals. It helps in the rehydration of salts in the body. Gargling with warm salt water can help soothe a scratchy throat and reduces throat pain. The salt pulls the mucus out of swollen, inflamed tissue and helps relieve the discomfort. A leech bites in your leg can be removed by adding salt on the leech. When leeches are doused in salt, it creates an osmotic pressure that draws moisture from their cells and kills them. Salt is used in the preservation of ripe tamarind because, it removes water from the cells of tamarind through osmosis. Hence, it creates an environment where bacteria cannot grow. If a symptom like low blood pressure is found in someone, we should give salt water. On increasing salt content, our body holds on to water to dilute it. This extra water increases the blood volume, therefore heart works harder to push more liquid through blood vessels. This increases the blood pressure of the body.
