Avena sativa means “wild oats” in Latin. This plant, also referred to as oat straw or oat extract, was used as a medicine prior to being used as food. This plant may have sparked the phrase, “sowing your wild oats,” due to its effect on sexual stimulation, according to “Prescription for Herbal Healing” by Phyllis A. Balch. Potential benefits are not limited to its impact on the libido, however. Wild oats are rich in B vitamins, phosphorous and calcium.

Sex Booster

Wild oats may be a mild sexual enhancer, according to Dr. Ray Sahelian, author of “Natural Sex Boosters.” However, he notes that most claims for sexual enhancement rely on research done in 1980s by the Institute for Advanced Study of Human Sexuality in San Francisco, a company that marketed avena sativa products. In the animal kingdom, Balch notes that stallions that are fed wild oats are said to become lustful.

Inflammation Fighter

Wild oats can help you fight inflammation, advises the Oregonian newspaper. A molecule in oats called avenanthramides helps reduce levels of inflammatory cytokines, which are immune system chemicals. Lowering cytokines is a good idea because when levels are high they raise risk for chronic conditions such as diabetes and heart disease, advise The YOU Docs columnists Mehmet Oz and Mike Roizen.

Heart Health Booster

Wild oats can boost heart health. Avena sativa helps you lower the “bad” low density lipoprotein, or LDL, cholesterol levels as well as overall cholesterol levels, according to a Canadian study published in the European Journal of Clinical Nutrition. This is due to the main component of the oats’ soluble fiber, called beta-glucan, according to lead study author J.T. Braaten of the University of Ottawa. Wild oats may help reduce your waistline at the same time, which further reduces risk for coronary heart disease, advises Venezuelan researcher N. Reyna-Villasmil, who authored a 2007 study published in the American Journal of Therapeutics. Avena sativa helps you to lower risk for heart-threatening blood clots and keeps your arteries flexible as well, according to Oz and Roizen.

ADD Helper

If you or a loved one suffers attention deficit disorder or attention deficit hyperactivity disorder, you may benefit from avena’s sedative properties, according to Balch. Herbalists use avena to reduce symptoms of methylphenidate withdrawal and to alleviate mild depression for adults with such conditions. However, science is lacking for this use, making it controversial. Before you try any sort of alternative therapy, especially one that is controversial, you need to consult with your doctor, advises the National Resource Center on AD/HD.

Other Uses

You may see Avena sativa advertised as an aid to help combat osteoporosis because it can boost hormone levels that stimulate cell growth. However, evidence for this use so far is lacking, according to the University of Maryland Medical Center.

Avena sativa also may help you if you suffer amenorrhea, meaning you’re not having a period. That’s because it is rich in minerals that potentially promote better thyroid function, according to UMMC. However, evidence for this use is based on traditional use rather than scientific study, so you need to consult with a doctor if you’d like to incorporate oat straw use into your regimen for treating this condition.

Oat straw sounds like a product farmers might feed to livestock, but it’s actually part of the same plant from which oat meal comes and has thanh phan vimaxbeen used in folk medicine as well as for food. In the Middle Ages, oat straw was touted as a brain booster, and more recently oat straw extract has been marketed as a sexual enhancement supplement. Since very few studies have investigated oat straw for these and other claims, use caution before adding oat straw extracts to your diet.


The mature oat plant produces the grain you know as oats, often promoted as a food that can lower cholesterol. Oat straw, however, is the green, unripe part of the plant, both leaves and stems, and is sold as Avena sativa, green oats or wild oat extract. You can find it in some health food stores and on the Internet as a powder, juice, tincture or as a tea.

Effects on Behavior and Mood

Oat straw’s use as a behavioral agent dates back to at least the Middle Ages. Wild oat extract has the ability to reduce the effects of two enzymes tied to depression the same way some prescription medications do. Researchers in Switzerland published study results in “Phytotherapy Research” in October 2009 showing that a wild green oat extract reduced stress and improved socialization behavior in rats. One of the only other studies to investigate oat straw’s effects on mood was sponsored by a company that manufactures a commercial oat straw product. The double-blind study, published in the “Journal of Alternative and Complementary Medicine” in May 2011, showed some improvements in cognitive performance in healthy subjects as measured by quantitative brain mapping technology.

Sexual Enhancement

In the 19th century, the German Pharmacopoeia listed Avena sativa as an aphrodisiac. Most of the commercial products on the market today use oat straw alone or in combination with other herbs like saw palmetto for sexual performance, claiming oat straw works by increasing the amount of testosterone in the blood. Much of the contemporary research for such claims has been conducted by the nonaccredited Institute for Advanced Study of Human Sexuality in San Francisco. One of the Institute’s double-blind, placebo-controlled trials of 75 men and women purportedly found oat straw enhanced sexual experience for men but not for women. A separate Institute study testing their oat straw product on impotent men found a partial response to treatment.

Smoking Cessation

Some evidence in the 1970s indicated that oat straw might be beneficial in helping smokers to quit, including one report, published in the journal “Nature,” of an Ayurvedic medical practitioner in India who had successfully treated both opium and cigarette addiction with oat straw. However, other studies since have showed negative or mixed results, such as a double-blind study published in the “International Journal of Clinical Pharmacology and Biophamacy” in October 1976, demonstrating Avena sativa had no effect on heavy smokers but moderate effects on helping light smokers break the habit.
