The biochemical effects on stress responses observed in experimental and human Ginseng—Siberian 581
studies provide a theoretical basis for this indication (Abramova et al 1972, Gaffney et al 2001a).
One placebo-controlled study conducted over 6 weeks investigated the effects of an ethanolic extract of Siberian ginseng (8 mL/day, equivalent to 4 g/day dried root). In the study, active treatment resulted in increased Cortisol levels, which may be consistent with animal research suggesting a threshold of stress below which Siberian ginseng increases the stress response and above which it decreases the stress response (Gaffney et al 2001 b).
