This time of year I start having allergy problems, particularly when I spend time outside working in the dusty leaves. I wake up the next morning kind stuffy, my ears burn and my throat hurts. Several years ago I started using a neti pot to help with my allergies so I wouldn’t have to take medication. I am now a HUGE fan of the neti pot and I use it all the time. It not only keeps my allergy symptoms at bay but it’s extremely useful for keeping colds/flu away and for helping with congestion when you have a cold/flu.
Many sources will tell you to only use kosher salt for your neti pot, but I use sea salt (usually Real Salt brand). I don’t like the idea of using refined salt in any application. Some people swear by using Himalayan salt, I just use what I have around for cooking so I don't have to buy a special box.
