Ginseng – especially Panax ginseng – is a widely researched plant species. Let me provide an indicative overview of some of the work related to the role of ginseng in anxiety management.
Traditionally, ginseng is regarded as both a physical and mental restorant. It is said to improve the cognitive ability of patients, improve the quality of life and behavior.
Studies conducted on healthy individuals given Panax ginseng doses of 200 mg of extract daily showed increased QTc interval and decreased diastolic blood pressure two hours after ingestion on the first day of therapy (Caron et al., 2002).
Traditionally, treatment with Panax ginseng has been used to lower blood glucose levels and improve cognitive abilities. A double-blind, placebo-controlled trial confirms that Panax ginseng may possess glucoregulatory properties and can enhance cognitive performance (Reay et al., 2005).
On the other hand, when the subjective mood and aspects of working memory processes in healthy volunteers were studied following treatment with Panax ginseng, no change was observed (Reay et al., 2010).
Another study indicated that the mental health and social functioning of patients improved after four weeks of therapy with Panax ginseng. This improvement attenuated with continued use (Ellis et al., 2002). Similar dose-dependent action of combination therapy with Ginkgo biloba and Panax ginseng was observed in healthy young volunteers (Scholey et al., 2002).
These studies do indicate the role of ginseng in anxiety management. However, most of this work is restricted to small groups of individuals. Extensive clinical trials that are widely distributed geographically and across a full range of subjects will be required to come to a definitive conclusion.
