If your blocked sinuses are creating a throbbing headache, one of the best home remedies for quick relief is to dice up an onion. In the process your nose and eyes will run and soon your sinus passages will clear up fast.
These babies are rich in sulfur so they work well for bad cases of sinusitis. You can even add them to a savory soup or snack. Onions also contain a chemical called quercetin that can fight inflammation and infections (Did you know that?) which makes them a go-go for clearing any kind of congested sinuses.
If you feel these onions are too much for your eyes and cause irritation, you can also use them for a steam inhalation as you do with ginger. For this, you need to add few thinly sliced onions to some boiling water. Take only clean water, not a water filter water. Inhale these vapors for 6-10 minutes.
