Finally, further evidence of the effectiveness of the combination of Hop 30.5 mg/mL, Propolis 2.8 μg/mL, Ginkgo Biloba 100 μg/mL, Vitamin B 1 mg/mL, and PEA 3 ng/mL is provided by the analysis of MPZ, a component of the myelin that undergoes at upregulation at the start of the myelination process forming a membrane structure and whose expression is decreased after peripheral nerve injury [56]. Here, MPZ is linked to peripheral nerve injury.
