By Kyle J. Norton

Whole food(herbal medicine) used as medical treatment,  linking health benefits in prevention, management and treatment of diseases has induced much interests in today renowned scientists.
But many researchers have raised question of herbal quality, because geographic differences, time of grown and harvest, etc. may effect their's potency. I do believe, these questions can only be answered by experience herbalists.

Modern study suggested that Asparagus extract (ETAS) may have a potential in improved Psychological Stress, the responded to the psychological stress questionnaires, conducted by a renowned institute indicated.

According to the randomized, double-blind, placebo-controlled cross-over trial undertaken in healthy volunteer, oral administration of ETAS (150 mg/d) consumed for 28 day, significantly upregulated the sympathetic nerve activity in reduced Psychological Stress.

Dr. Takanari J, the lead author in the study said, " ETAS significantly increased the number of answers and the number of correct answers in the U-K test, suggesting that it might improve office work performance with swiftness and accuracy under stressful conditions" and "ETAS intake may exert beneficial effects, resulting from well-controlled stress management, in healthy individuals.".

Asparagus is a flowering plant belong to species the genus Asparagus, native to the western coasts of northern Spain, north to Ireland, Great Britain, and northwest Germany, northern Africa and western Asia,  used from early times as a vegetable and medicine, because of its delicate flavour and diuretic properties.


A study to investigate the efficacy of the extract against psychological tress, standardized methanolic extract of Asparagus racemosus (MAR) (50, 100, and 200 mg/kg, per oral) administered for 7 days, in comparison to intake of Lorazepam (0.5 mg/kg, intraperitoneal) used as a positive control, conducted by the Indian Institute of Technology (Banaras Hindu University, suggested that the herbal extract improves psychological stress through a physiological modulation of the stress pathways with limited change on monoaminergic systems in comparison to controls.

The study also stated that this efficacy may also be contributed to decrease the plasma corticosterone (CORT) and norepinephrine (NE), levels which control the stress aspect during certain stressful events.

Monoamine is a neurostransmitter including dopamine, noradrenaline, adrenaline and serotonin played an important role in regulated on arousal, emotion and cognition.

Dr. Joshi T and colleagues at the Kumaun University, also expressed the usefulness of ethanolic extract of the roots of A. racemosus in ameliorating restraint stress in induced elevation of blood glucose, triglyceride and cholesterol levels, as well as stress induced variations in levels of lipid peroxidation, nitric oxide, protein and glutathione content in mouse brain..

Taking together, Asparagus and its extract may consist a potential effect in reduced psychological stress through expression of stress hormone and antioxidant in a physiological modulation of the stress pathways.
