“…For centuries, MO has been used in traditional Chinese medicine (TCM), traditional Persian medicine (TPM), Ayurvedic medicine, Arabic medicine, and medieval European medicine for treating diverse health conditions, such as insomnia, migraines, neuroses, and hysteria, among others ( Shakeri et al, 2016 ). In the modern pharmacological studies, various human clinical trials ( Kennedy et al, 2002 ; Akhondzadeh et al, 2003 ; Kennedy et al, 2003 ; Kennedy et al, 2004 ; Kennedy et al, 2006 ; Cases et al, 2011 ; Alijaniha et al, 2015 ; Ranjbar et al, 2018a ; Ranjbar et al, 2018b ; Haybar et al, 2018 ; Heydari et al, 2018 ; Soltanpour et al, 2019 ; Araj-Khodaei et al, 2020 ; Noguchi-Shinohara et al, 2020 ; Shirazi et al, 2021 ), animal models ( Coleta et al, 2001 ; Guginski et al, 2009 ; Ibarra et al, 2010 ; Yoo et al, 2011 ; Taiwo et al, 2012 ; Feliú-Hemmelmann et al, 2013 ; Lin et al, 2015 ; Ghazizadeh et al, 2020 ; Talebi et al, 2022 ), and in vitro studies ( Kennedy et al, 2003 ; Awad et al, 2007 ; Awad et al, 2009 ; López et al, 2009 ; Sahin et al, 2016 ) have investigated the neurotherapeutic effects of MO extract, with most studies reporting its antidepressant, anti-stress, anxiolytic, anti-insomnia, and anti-oxidative stress (neuroprotective) properties. According to reported evidence, the neuropharmacological effects of MO extract are due to its various biological properties, i.e., its GABAergic properties (upregulation of γ-amino butyric acid (GABA) through GABA-transaminase (GABA-T) inhibition ( Awad et al, 2007 ; Awad et al, 2009 ; Yoo et al, 2011 ), GABA A receptor affinity ( Salah and Jäger, 2005 ; Abuhamdah et al, 2008 ; Sahin et al, 2016 )), modulation of the serotonergic pathway ( Dimpfel and Suter, 2008 ; Lin et al, 2015 ), and inhibition of acetylcholine esterase (AChE) ( Perry et al, 1996 ; Ferreira et al, 2006 ; Dastmalchi et al, 2009 ) and monoamine oxidase (MAO) enzymes ( Ulbricht et al, 2005 ; López et al, 2009 ; Taiwo ...…”
