An alternative to the real ginseng

Uses: People use eleuthero in attempts to improve physical endurance, concentration, memory and energy and to combat fatigue and illness.

Dose: Usually about 200 milligrams two times a day; available in pills or liquid and as leaves for making tea.

Precautions: Eleuthero is not recommended for people with high blood pressure or heart conditions, for people with diabetes (it could lower blood sugar) or for those taking anticoagulants (it might thin the blood). The herb can cause anxiety, insomnia, heart palpitations and headaches, and it shouldn’t be taken for more than two months at a time, because long-term use increases the risk of muscle spasms.

Research: Most of the research on eleuthero has been done in Russia and other parts of Asia. Studies on the herb’s effects on physical endurance have produced mixed results. Animal and some human studies on eleuthero show that the herb does increase heart rate and blood pressure.
