Where can you buy agave nectar?

Just try gargling with salt water. 1/2 tsp to 1/2 gl of warm water. It acts as astringent and cleanses the throat. Can repeat every couple of hours, and don't swallow the salt. Can increase your Vit C and echanaecia to enhance immune system. If you have post nasal drip causing the sore throat, might want to treat that as well (I use benadryl...works great).
