Migraine , migraine - like headaches , and neuralgia are a common problem today . Considerable evidence supports an association between migraine headache and vasomotor instability ,but the mechanisms are not yet known (1).
The mechanism of migraine can be described as a three- stage process :
initiation , prodrome , and headache . Although , a particular stressor may be associated with the onset of a specific attack , it appears that initiation is dependent on accumulation over time of several stressors . These stressors ultimately affect serotonin metabolism (2).
Once a critical point of susceptibility is reached , a cascade event is initiated :
.decreased tissue serotonine levels. Changes in the platelet , alteration in responsiveness of key cerebrovascular end – organs and the build up of histamine , arachidonic acid metabolites , or other mediators of inflammation (3).
Antimigraine herbal drop is a combination of several plant extracts and is able to relieve the patients from the severe headache . In a clinical trial in two groups of 35 patients with migraine headache , one group was treated with antimigraine drop for 12 weeks and another group with propranolol for the same period of time . The results showed that both drugs were equally effective in reducing the intensity , frequency and the duration of headache , however , the patients were more satisfied with antimigraine compare to propranrolol (4,5) .
The mechanism of action of antimigraine is :
Valepotriates and valerenic acid binds to GABA receptors in a similar fashion to benzodiazepines (6,7) ,
and induce sedation . The sedative action of the constituents of Valeriana officinalis overall , can inhibit the stressors by which migraine headache is initiated . Also , salicin and other phenol glycosides from Salix alba inhibit the synthesis of prostaglandins and has a potent anti-inflammatory and analgesic effect therefore ,it can relieve the patient headache effectively .
