If you have a soar throat eat garlic because garlic contains an antibacterial and antiviral agent and even you can get garlic pills which comes very handy...
what you are referring to is sore throat, mainly caused by viral infection. Gargling every few hours with hot water in which a pinch of salt and turmeric added provides relief. Also chewing a clove of raw garlic with a pinch of ajwain and a fresh betel leaf is very soothing to throat.
