I was suffering from a terrible sinus headache. I tried the tomato tea remedy, but to no avail. Then I gave the steamed ACV/water mixture a shot. It has worked wonders. What a relief! I simply inhaled the fumes lightly after bringing one part ACV and one part water to a boil. I did this once last night, and it brought much relief. After waking this morning, I still had a bit of a headache so I did it once more. Now the sinus headache is practically gone. I highly recommend this remedy, especially for people whose stomachs cannot tolerate in taking some of the other remedies.
