A review on therapeutic potentials of Trigonella foenum graecum (fenugreek) and its chemical constituents in neurological disorders: Complementary roles to its hypolipidemic,hypoglycemic, and antioxidant potential

Objectives: The growing rate of neurological disorders is a major concern in today's scenario. Today's research is focusing on therapeutic interventions providing benefits in these disorders. Presently, drugs of natural origin have gained more interest for the treatment of central nervous system disorders for their efficacy and less/ no side effects. This review is emphasizing the cited roles of Trigonella foenum graecum (fenugreek) and its constituents in different neurological manifestations.

Method: A review of the literature, relevant to the role of fenugreek and its major constituents including saponins and alkaloids in different neurological aspects and in delineating the health benefits, was conducted.

Results: The cited research acknowledged that fenugreek and its constituents exert positive influence on neurological health. Few studies have reported the beneficial role of fenugreek and its constituents like trigonelline in pathological symptoms of Alzheimer's disease. Similarly, other studies evidenced the neuroprotective, antidepressant, antianxiety as well as modulatory effect on cognitive functions and Parkinson's disease.

Discussion: Large populations are the sufferers of the neurological disorders, pointing the need for investigation of such therapeutic interventions which target and delay the underlying pathological hallmarks and exert positive influence on different neurological health problems. Hypolipidemic, hypoglycemic, antioxidant, and immunomodulatory effects of fenugreek and its constituents with their potential role in various neurological disorders were already reported. In future, it would be of even greater interest to further develop more effective dosage, supplementation period, and to evaluate the therapeutic potentials of fenugreek and its constituents in neurological disorders by exploring underlying cellular and molecular mechanisms.
