Medical treatment is one choice. There are new drugs available that are designed to stop a migraine that has already gotten going. Some of the drug names are Zomig, Imitrex and Maxalt. These drugs cause the blood vessels around the trigeminal nerve to constrict and relieve the pain of the migraine. There are some homeopathic options for treating a migraine that has already gotten started.
Passionflower is a natural tranquilizer that can ease pain for some people.
It can be purchased in capsule form or oil. Try adding 15 to 20 drops of the oil to a cup of tea. Practice all precautions using passionflower that you would using any other tranquilizer. Rosemary oil rubbed into the temples may also relieve a migraine. Some people find rosemary tea soothing as well.
