I've been a lifelong sufferer of allergies, sinusitus and sinus infections and I think I've finally found some relief! This dry fall has been horrible for allergies here in Minnesota and for about 5 days now I've been taking 2 tablespoons of organic apple cider vinegar (I use Bragg's) and one tablespoon of local honey in a glass of water 2 times a day. I must say I've been feeling a whole lot better! Granted, the allergies symptoms aren't totally gone but the sinus congestion is definitely much, much better. Not the most tasty concoction but hey it works for me!
I'd give apple cider vinegar and honey a try for any kind of sinus congestion!
