In this study, participants are asked to:
* Apply an adequate amount of Canvert-M roll-on to the areas of the forehead, temporal, behind the ears, and base of the neck, at the onset of a migraine attack. (If the participant's headache persists after 30 minutes, a second dose can be used.)
* Record the date when the headache occurred.
* Record the severity of the headache at various time points (before using Canvert-M, and then at 30 minutes, 60 minutes, 120 minutes, 4 hours, and 24 hours after using the Canvert-M roll-on) based on the 4-point scale.
* As much as possible, avoid using any other analgesics for two hours after applying Canvert-M. However, if the headache persists after two hours, the participant may use another medication and should record the name(s) of the drug(s) taken.
* Record a general evaluation of the effectiveness of the investigational product using a simple Likert-type verbal scale.
