Neuroprotective effects are the protection against anything which causes harm to the brain and spinal cord
In other words, herbal butterbur promotes neuronal integrity against the reduction in the rate of neuronal loss that cause neuro degenerative disease.
Dr. Vajda FJ, the scientist at the St. Vincent's Hospital, Melbourne in expression of neuro diseases said, "neuroprotection is an effect that may result in salvage, recovery or regeneration of the nervous system, its cells, structure and function. It is thought that there are many neurochemical modulators of nervous system damage" and " Acute and chronic nervous system damage in response to an insult may lead to acute or delayed neuronal death, apoptotic cell death, neuronal degeneration, injury and loss, and gliosis"(4).
The Mcgovern Istitute in the article related to brain disorder wrote, "Many brain disorders are chronic and incurable conditions whose disabling effects may continue for years or even decades. Thus, the overall disease burden from these disorders is much greater than would be suggested by mortality figures alone. The extent of this burden is underlined by data from the World Health Organization".
Butterbur, found in wet, marshy, damp land, including wetland, riverside, forest, etc., is a creeping underground plant, genus Petasites of 15 -20 species, belongings to the family Asteraceae, native to Northern Hemisphere.
The herbal medicine has been used in herbal medicine as an pain reliever in digestive system, including stomach, bile ducts,...... and duodenum.
The chemical constituents of Butterbur include Petioles, petasitene and pethybrene, quercetin 3-O-beta-D-glucoside, quercetin 3-O-beta-D-6''-O-acetylglucoside, and rutin, caffeic acid, alkaloids, S-petasin and iso-S-petasin, etc.
In the study to investigate neuroprotective effects in a rat transient focal cerebral ischemia-reperfusion model, and in an in vitro cerebral ischemia model, oxygen-glucose deprivation of cultured nerve cells, researchers found that application of total bakkenolides, a major bioactive constituent isolated immediately after reperfusion at doses of 5, 10 and 20 mg/kg markedly reduced brain infarct volume and neurological deficits.
Moreover, petaslignolide A (PA), a furfuran lignan isolated from butanol fraction of Petasites japonicus (Sieb. et Zucc.) (Compositae) leaves in study of the oxidative damage in the brain of mice, facilitated a significant effect at dose of 40 mg/kg in alleviated the behavioral signs of kainic acid neurotoxicity and reduced the mortality (50%) by kainic acid to 12.5%.
Administration of PA also restore the levels of antioxidants in the mice that were reduced by injection of kainic acid in compared to control.
However, further data collection on large example size and multi centers studies performed with human consumption of the whole food during the course of the disease will be necessary to complete the picture of butterbur neuro protective possibilities.
