For sinus headache, I create a mixture of ground ginger and water. Consistency is a matter of personal preference- I mix equal parts ginger and water and use a basting brush to put it on my forehead. If the headaches not too bad, it takes care of it within a half hour.
Regarding Ginger Root- I have found it to be excellent in opening sinuses. I drink a cup in the morning and evening. Cut thumb size piece of fresh ginger root into slices, in small tea cup, add water, microwave until just boiling. Let sit for a while; the longer the stronger the tea. Add small tsp. honey. Delicious, peppery. Lowers blood pressure also.
Have read that too much can thin the blood so be careful is on prescription blood thinners. Also have read warnings regarding gallbladder problems, if you suffer this already.
Ginger for a Sinus Headache: I don't have fresh ginger root, I have ginger in a tube. I figured, I'll try it with the ginger that I have. I put in about 1 very large tablespoon or more of ginger into a 6 or 8 oz glass, then boiled up 1 cup of water. I added some organic honey. I wasn't expecting this to work, but it worked almost immediately!
I would say it's not quite what you would get from Ibuprofen, or sudafed, but very very close, and it will take the pain away, and it's natural! I am sick of taking ibuprofen for my sinus headaches. They WORK, but, if this method works for me I would rather go this route. I have had sinus headaches for years. The pain is unbearable. It's been 20 mins since I tried it. I will keep this window open and continue to monitor if it's working or not. Ok it has been an hour. I definitely DO feel better. I would say it's worth it to do.
