Feeling a cold coming on in scratchy thoat /sore throat. what can i do to fight this?

Common cold?: Rest, fluids, healthy diet and time will fight this as effectively as anything else available assuming it is viral. If you see a doctor they may want to culture or test your throat for strep.

Sore throat: If you have a significantly sore throat w swollen tonsils / lymph nodes – see your medical provider ; get a strep throat test ; culture. Saltwater gargles are helpful. Mix a tsp of salt in 8 oz of warm water – gargle w this several times/day. You can gargle w aloe vera juice a couple of times per day. A mix of chamomile tea w honey ; a small amount of lemon juice is good.
