with some Honey,drink it warm , gargle
with salt water ,put a couple of spoons of salt ina glass of warm water and gargle like you do mouthwash,I would do it a couple of times a day.I believe Llarangitas can take a little while and if you had a nasty case of it, so maybe it will be clearing as I type,Hope you are better soon.
