Background

Verbena (Verbena officinalis) is a perennial herb native to Europe. Verbena was considered a sacred plant in northern Europe and is said to have been included in love potions. It has been used traditionally in Italian folk medicine for rheumatic pain and wounds and in Ayurvedic medicine as a contraceptive. Verbena is said to be a medicinal plant in Argentina and Paraguay.
Preliminary research suggests potential antioxidant, neurological, and endocrine actions of verbena. However, there is currently insufficient scientific evidence available to support the use of verbena for any condition in humans.

Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Dosing

Adults (18 years and older)
There is no proven safe or effective dose for verbena in adults.

Safety

The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Interactions

Interactions with Drugs
Verbena may alter the risk of bleeding, as it contains vitamin K, which is needed for blood clotting. Verbena may reduce the effectiveness of oral anticoagulant therapy. Verbena may change the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants (blood thinners) such as warfarin (Coumadin?) or heparin, antiplatelet drugs such as clopidogrel (Plavix?), and nonsteroidal anti-inflammatory drugs such as ibuprofen (Motrin?, Advil?) or naproxen (Naprosyn?, Aleve?).
Verbena may cause changes in blood pressure. Caution is advised in patients taking drugs that affect blood pressure.
Verbena may interfere with the way the body processes certain drugs using the liver's cytochrome P450 enzyme system. As a result, the levels of these drugs may be changed in the blood and may cause increased or decreased effects or potentially serious adverse reactions. Patients using any medications should check the package insert and speak with a qualified healthcare professional, including a pharmacist, about possible interactions.
Because verbena contains estrogen-like chemicals, the effects of other agents believed to have estrogen-like properties may be altered.
Verbena may also interact with antibiotics, anticancer drugs, anti-inflammatory agents, antioxidants, drugs taken by mouth, drugs to prevent kidney stones, fertility agents, gastrointestinal agents (prokinetic), iron, neurological blocking agents, or progestins.
