How does eleuthero work (mechanism of action)?

Eleuthero is a plant called Eleutherococcus senticosus. Dietary supplements that contain eleuthero are made from the root (rhizome) of the plant. In the traditional Chinese medicine system, eleuthero root is known as ci wu jia. Since the plant is native to Russia and Northern Asia, it is also sometimes called Siberian ginseng. But it is not actually a type of ginseng and does not contain the same chemicals as true ginseng varieties, such as Panax ginseng and American ginseng.

Eleuthero is thought to act as an adaptogen, which is a substance that helps the body respond to stressful changes in its environment. But the benefits of taking eleuthero as an adaptogen are not well defined. In most studies, eleuthero has been used with other herbs and ingredients. Research on the use of eleuthero alone seems to show that it does not increase energy levels, physical performance, or immune function by a meaningful amount.

Herbal products, such as eleuthero, naturally contain many chemicals. The amounts of each chemical in a specific eleuthero product may vary. Some, none, or all of these chemicals may have effects on the body. These effects may change depending on how much of each chemical is found in the product you are taking.

How should I store eleuthero?

You should store eleuthero according to the product label. Most dietary supplements should be kept in a cool, dry location that is out of the reach of children and pets and not in direct sunlight.

Side Effects

Eleuthero seems to be well tolerated. The most commonly reported side effect is trouble sleeping (insomnia). Side effects may vary depending on the dose you are taking or the specific product you are taking. Tell your health care provider if you have any side effects that bother you.

There may be other side effects of eleuthero that are not listed here. Contact your health care provider if you think you are having a side effect of a supplement.

Herbal products, such as eleuthero, naturally contain many chemicals. The amount of each chemical in a specific eleuthero product can change for many reasons, including the area where the plant was grown, the weather during growth, the time of year when it was harvested, and the way that the plant was processed after it was harvested. If you switch to a new bottle or a different brand, you may not have the same effects or side effects because of this variability. Talk to your health care provider if you have questions or concerns.

Eleuthero is available in many forms, including a liquid extract, tea, dried and ground powder, and capsule. Each of these forms may contain different amounts of the chemicals that are naturally found in the plant.

If you are using eleuthero powder, use an appropriate measuring device to measure the powder, such as the device included with the product. If you are using eleuthero liquid extract, use an accurate measuring device to measure your dose. A household spoon is not an accurate measuring device and may cause you to take the wrong dose. Read the product label carefully, and follow the instructions on the label.

The FDA has not tested eleuthero products to confirm that they contain the ingredients stated on their labels. Some dietary supplements have been tested by third-party organizations to confirm that they contain the ingredients listed on their labels and do not contain any harmful chemicals.
