Plants in the ginseng/eleuthero families are generally considered quite safe (that’s part of the definition they must fulfill to be termed an adaptogen). There are no known drug interactions, contraindications, common allergic reactions or toxicity to Siberian ginseng. A word of caution is recommended, however, for individuals with hypertension, as the stimulatory nature of some ginseng preparations, including eleuthero, have been reported to increase blood pressure.
While the scientific evidence for the benefits of eleuthero and its mechanisms of action can be considered supported only for the standardized extracts, the general adaptogenic role of the entire family of “ginsengs” have proven beneficial for many thousands of years and may, therefore, prove valuable as normalizing substances during stressful conditions. Eleuthero is best supplemented as a standardized extract (100-300mg/day with 0.5-1.0% eleutherosides) to ensure that you are getting an effective product.
