There is this magical sore throat gargle called Trachisan, and I consider it the best sore throat medicine ever. When I was in the US, I was using Chloraseptic spray which I considered the best for a long time. It is very easy to use, all it takes is spraying the throat few times and it will be good to go. Trachisan is much stronger in terms of relieving the pain and it lasts much longer. Right now I always have backup of Trachisan in case someone becomes sick at my home. Trachisan gargle come in 200 ML, so make sure you get the gargle and not their other products.
