Ginseng’s effect on human metabolism has been studied in a few experiments. I am presenting one such study to illustrate the fact the impact of chemicals on the body is immediate irrespective of the source- herbal or chemical. As you would observe in the abstract below the impact measurements were taken at 1, 2, and 3 hours after the intervention, and changes were observed.

Ginsenoside Rg3, present in steamed ginseng (Panax Ginseng C.A. Meyer), is thought to be a potent modulator of vascular function. Acute effects of ginsenoside Rg3–enriched Korean red ginseng (Rg3-KRG) on measures of arterial stiffness and peripheral and central blood pressure (BP) parameters in healthy volunteers were studied. Using a double-blind, randomized, crossover design, 23 individuals (9 males:14 females; age, 25 ± 2 years; body mass index, 22 ± 0.6 kg/m 2; systolic BP/diastolic BP, 113 ± 3/70 ± 2 mm Hg) were administered 400-mg Rg3-KRG extract or 400-mg wheat bran control on two separate visits with a 7-day washout period.

Measurements were taken at baseline and at 1, 2, and 3 hours after the intervention. Compared with control, there were significant reductions in augmentation index (−4.3 ± 8.9%, P = .03), central (−4.8 ± 6.8 mm Hg, P = .01) and brachial mean arterial pressure (−4.4 ± 6.6 mm Hg, P = .01), central systolic (−5.0 ± 7.9 mm Hg, P = .01) and diastolic BP (−3.9 ± 6.6 mm Hg, P = .01), and brachial systolic (−4.4 ± 10.0 mm Hg, P = .048) and diastolic BP (−3.6 ± 6.4 mm Hg, P = .01) at 3 hours after intervention compared with control.

Most of the modern medicines in use today were discovered and isolated from plants. When the impact of these medicines is instant, how can this be different in the case of ginseng is a question for pondering. I have seen the same phenomenon in the course of my research on other herbs.
