The leaves of damiana were originally used as medicine by the indigenous cultures of Central America, particularly Mexico. Today the plant is found in hot, humid climates, including Mexico and parts of Texas, the Caribbean, and southern Africa.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 StarsReliable and relatively consistent scientific data showing a substantial health benefit.
2 StarsContradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 StarFor an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
Refer to label instructions
Damiana has traditionally been used to treat people with depression. Yohimbine (the active component of the herb yohimbe) inhibits monoamine oxidase (MAO) and therefore may be beneficial in depressive disorders. However, clinical research has not been conducted for its use in treating depression.
Refer to label instructions
Damiana(Turnera diffusa) is a traditional herbal treatment for men with ED. However, no modern clinical trials have confirmed its effectiveness.
Traditional Use (May Not Be Supported by Scientific Studies)
Damiana has been hailed as an aphrodisiac since ancient times, particularly by the native peoples of Mexico.1 Other folk uses have included asthma, bronchitis, neurosis, and various sexual disorders.2 It has also been promoted as a euphoria-inducing substance.
How It Works
How It Works
Most research has been done on the volatile oil of damiana, which includes numerous small, fragrant substances called terpenes.3 As yet, it is unclear if the volatile oil is truly the main active constituent of damiana. Damiana extracts have been shown, in a test tube, to weakly bind to progesterone receptors.4 Thus, damiana may be a potentially useful herb for some female health problems. However, no human studies have investigated this possibility and it is not a primary traditional use.
How to Use It
To make a tea, add 1 cup (250 ml) boiling water to 1/4 teaspoon (1 gram) of dried leaves and allow to steep for ten to fifteen minutes. People can drink three cups (750 ml) per day. To use in tincture form, take 1/2–3/4 teaspoon (2–3 ml) three times daily. Tablets or capsules (400–800 mg three times per day) may also be used. Damiana is commonly used in herbal combinations. However, the authors of the German Commission E monographs do not feel that traditional use of this herb is justified by modern research.5
