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.

Asparagus, one the miracle food is found to process significant antioxidant effects in enhancing immune system fighting against forming of free radicals and foreign invasion.

Antioxidant is a molecule inhibited oxidative free radicals before they can cause any damage to the host, through domino's activities.

According to the joint study lead by the National Institute of Neuroscience, National Center of Neurology and Psychiatry, Tokyo, extracts of Asparagus cochinchinensis (AC) exhibited anti-inflammatory effects by inhibited H2O2-induced cell death in cultured cortical neurons in protection against the free radical causes of depressant and neuro cells apoptosis.

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.

Dr. Lee JW1, the lead researcher suggested, these effects appear to be associated with activation of the Shp-2, antibody and ErK1/2 Akt and Akt pathways involved the cell apoptosis, cell proliferation.

The study of four fractions viz. methanol (MF), ethyl acetate (EF), n-Butanol (BF), and precipitated aqueous (PAF) of A.racemosus root also found that the constituents exerted significantly antioxidant properties in inhibition of free radicals by raising serum antioxidant enzymes such as. superoxide dismutase and reduced glutathione and catalase.

The 4 faction also induced hepaprotective activity through inhibition of the formation of lipid peroxides in the liver of rats pretreated with the extracts.

Furthermore, in a total of 80 Kun Ming mice randomly divided into four groups (20/group), the mice in the control group received a daily subcutaneous injection of saline; A daily injection of D-galactose administered to the aging model group, the vitamin C (Vc) group (positive control group), and the extract treatment group, group with extract treatment, the aqueous extract of A. cochinchinensis (Lour.) Merr. increased antioxidant effects of nitric oxide synthase (NOS), catalase (CAT), superoxide dismutase (SOD) activities, and reduced the MDA content, a marker for oxidative stress (p < 0.05), in compared with other groups.

In vivo and in vitro, Dr, Lei L the lead author of the study said, " The aqueous extract of A. cochinchinensis (Lour.) Merr. shoot, had a strong radical scavenging capability in vivo and in vitro, and might be used to diminish radicals in the body and consequently prevent aging".

In fact, the efficacy of asparagus, probably is due to the presence of abundant phytichemicals flavonoids, phenolics and best antioxidant potential among different fractions of crude methanol extract such as catechin, caffeic acid, rutin, myricetin and quercetin, according to the Quaid-i-Azam University.

There is no doubt that asparagus may be the best antioxidant whole food used to improve immune system against the free radical cause of diseases. People with weaken immunity due to aging should add a portion of asparagus into their diet.
