In one study, people who regularly experienced cluster
headaches rubbed a capsaicin preparation on and inside
their nose on the same side of the head as their pain.
Within five days, 75 percent reported less pain and fewer
headaches. If you suffer from cluster headaches, ask
your doctor about prescribing a capsaicin treatment.
