apigenin and Migraine-Disorders

Herbal treatments are often used as a treatment for migraine. Therefore, an evaluation of their safety and efficacy is important. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and Cochrane Collaboration's tool for assessing the risk of bias, a systematic literature review of randomised, controlled human trials assessing the effects of herbal treatments delivered as a single ingredient for the acute or prophylactic treatment of migraine were conducted. Studies were identified through electronic database searches on Medline (Pubmed), Cochrane Library, Scopus, and CINAHL. Nineteen studies were identified examining the effects on migraine of feverfew, butterbur, curcumin, menthol/peppermint oil, coriander, citron, Damask rose, chamomile, and lavender. Overall, findings on the efficacy of feverfew were mixed and there was positive, albeit limited evidence for butterbur. There were positive, preliminary findings on curcumin, citron, and coriander as a prophylactic treatment for migraine, and the use of menthol and chamomile as an acute treatment. However, the risk of bias was high for many studies. The results of this systematic review suggest that several herbal medicines, via their multifactorial physiological influences, present as potential options to enhance the treatment of migraine. However, further high-quality research is essential to examine their efficacy and safety as a treatment for migraine.

Migraine is a chronic recurring headache for which no complete treatment has been found yet. Therefore, finding new treatment approaches and medicines is important. In this review, we consider the probable mechanism of action of a traditional and ethnic formulary of chamomile extract in sesame oil as a new topical medication for migraine pain relief. Chamomile oil is prepared in Traditional Persian Medicine by boiling aqueous extract of chamomile in sesame oil. To optimize the procedure, we can use a Clevenger-type apparatus to extract the essential oil and add it to the end product. The preparation includes both essential oils (chamazulene and bisabolol oxide) and polyphenols (a flavonoid such as apigenin and its derivatives). It probably possesses pain relief effects for migraines because of the following properties: (1) chamazulene and apigenin, which inhibit iNOS expression in activated macrophages and can lead to the prohibition of NO release and synthesis; (2) chamomile flavonoids, which have a strong inhibitory effect on endogenous prostaglandin E2 (PGE2) levels in RAW 264.7 macrophages and can play the role of selective COX-2 inhibitor; (3) chamomile polyphenols, which possess anti-inflammatory effects due to the inhibition of pro-inflammatory biomarkers in THP1 macrophages and which can reduce inflammation in neurovascular units (NVU) at the site of migraine pain; (4) chamomile, which has neuroprotective effects because of reduced NO levels; (5) sesamine in sesame oil, which possesses an anti-inflammatory effect. These effects are supported by main pathophysiological theories of migraine such as neural and sensitization theories. Chamomile oil is a traditional formulation still used in Iran as an ethno-medicine. Because of the mentioned mechanisms of action, it can be hypothesized that chamomile oil is a novel medicine for the relief of migraine pain.
