Yes the cayenne pepper works wonders. so does baking soda because of its alkalinity. (bacteria love an acidic environment) But I highly recommend putting a roll of toilet paper in the freezer for when you need it, and boy will you need it. I felt like i was giving birth to a marine distress flare on the toilet.
Also something that is of "enormous" help. WARMTH. keep the neck area warm as possible with a large towel. and sleep with it on all night. you'll be amazed at what a difference it makes. White blood cells in your saliva love love loves warmth, and they are more active in a warm environment.
SO WHAT WORKS FOR ME. First gargle apple cider to quickly remove the flem to expose the bacteria or virus, then hit it with baking soda. the baking soda makes the infected area alkaline. then hit it with the cayenne pepper. then wrap up the neck area with a towel and sleep with it on. If that doesn't work, I'll be dammed !
