Eleuthero is used in herbal medicine as a tonic to help relieve a state of weakness or to help during convalescence. It may be used in herbal medicine to help improve mental and/or physical performance after periods of mental and/or physical activity.

Traditionally, eleuthero has been used as an adaptogen to help increase endurance, to improve memory, to boost the immune system, and for overall well-being. There are few clinical studies to show whether eleuthero is effective for these uses.

There are some clinical studies that show eleuthero may be effective in improving symptoms of the common cold when started within 3 days of the start of cold symptoms. However, in these studies eleuthero was used in combination with another herb called andrographis.
