I believe that most of your moms always tell you to drink a glass of salt water/rinse your mouth with salt water if you have a sore throat because salt can reduce inflammation.

This method has actually been proven (medically) to be really effective and it really can help to reduce inflammation. They have also tested on other medical values of salt and found out that: If you have pain in your joints/spine/body, you can simply try out this method which can help to relieve the pain (especially for old people who have rheumatism). Simply fry the salt let it settle down for a while before applying on affected areas.

And if you have a problem of Hair Loss, you can simply prepare a pail of salt water and rinse your scalp/hair with it (it takes about 2 weeks to a month). It will not help in growing of new hair but can prevent. After tedious/strenuous exercise, soaking your feet with salt water can help to prevent cramps and pain and also prevent from skin irritation. Hope it will be of help to you.
