Dan I would like to comment on your statement of potentcy. The standard for pharmaceuticals is measured in miligrams which varies in potentcy by numbers obviously the higher the number, the higher the dosage, the stronger the potentcy. The higher the miligram for one person could kill another. For example I'm on 10 miligrams of methadone this same dosage given to you could possibly put you in the hospital with an overdose causing some kind of complication. What I'm trying to get at is how does one measure the potency of herbal medicine?
You put a salt and warm water mixture in something that looks like a little teapot. Then pour it through one nostril and let it drain out the other. You have to practice a little, but once you get the hang of it, it can ease allergy or cold symptoms and may even help you get rid of a cold quicker. Just make sure you use distilled or cooled boiled water and keep your neti pot clean.
Try relaxing magnesium (200 to 400 mg) to reduce the muscle tension and spasms that can cause your noggin to throb. But not any type will do. Make sure the supplement contains at least 200 mg of active elemental magnesium. Because magnesium is more preventive than curative, the treatment works best on, say, premenstrual headaches because you can predict when they're coming and take a dose a day in advance. Those with kidney problems should consult a health care practitioner before taking magnesium. (Here are 3 more natural remedies for your headache.)
