What to Know About Aphrodisiac Supplements

Long before lust-boosting pills came along, men and women used herbs, scents and foods as aphrodisiacs. But which natural products really work?

Is your sex life as good as you’d like it to be? If not, you’re not alone. More than one in three women have low sexual desire, according to a survey of about 31, 000 U.S. women published in the November 2008 issue of Obstetrics & Gynecology. So it’s not surprising that a growing number of herbal supplements specifically formulated for women are springing up in drug- and health food stores, with intriguing names such as Sex Essentials and Libido. Among the advertised promises: “bring back desire,” “improve lubrication” and “aid orgasm.” Is it all hype? Or do natural remedies really help?

How do we know natural aphrodisiacs work?

Definitive studies on long-term efficacy and safety simply don’t exist yet, mainly because pharmaceutical companies are reluctant to fund research on natural products, which can’t be patented. “However,” says Sherry Torkos, a holistic pharmacist in Ridgeway, Ont., and author of The Canadian Encyclopedia of Natural Medicine, what we do have is thousands of years of use of these substances in other cultures.” When women come to her complaining of low libido, Torkos first makes sure they have been checked for medical problems, such as low thyroid or chronic stress, before suggesting they try an aphrodisiac supplement. But judging by the positive feedback, she says, “I think some of these supplements can help sexual desire and arousal.”

How they might work isn’t well understood, but “dozens of substances can have an effect on the brain chemistry that influences sexuality,” says Dr. Ray Sahelian, a physician in Los Angeles who also has a degree in nutrition science. The author of Natural Sex Boosters, Sahelian has tried a number of natural substances himself and contends, “There is such a thing as a natural aphrodisiac.”

With the recent legalization of cannabis in Canada, there’s also a growing interest in using cannabis as an aphrodisiac. How does it work? In a nutshell, CBD is a non-psychoactive cannabinoid that lends a hand in helping your body relax, and THC, which is the cannabinoid that produces a psychoactive effect (known as a “head high”), acts as an aphrodisiac, stimulating your sense of arousal for increased sensitivity and an intensified orgasm. Three recent reports on cannabis consumption show that around two-thirds of users find it sex-enhancing, according to Psychology Today.

Research on natural aphrodisiacs

Other than cannabis, there are a small number of international medical studies which suggest that some substances and scents may indeed hold promise:

• According to a 2008 study from India’s Banaras Hindu University, liquid extract from clove flowers (used in indigenous medicine to treat male sexual disorders) raised serum testosterone levels in mice.
• A special concentration of black tea made from the camellia sinensis tea plant has shown marked aphrodisiac activity in rats, a 2008 Sri Lankan study found.
• A 2007 study from the Second University of Naples in Italy found women with metabolic syndrome (a condition in which hypertension, insulin resistance, abdominal obesity and abnormal cholesterol levels are all present) had better sexual function after two years on a Mediterranean diet (mainly fruit, vegetables, nuts, whole grains and olive oil).
• Research by the Smell & Taste Treatment and Research Foundation in Chicago found that men had an increase in blood flow to the penis when exposed to the combined scents of pumpkin pie and lavender. Pumpkin pie often contains nutmeg, and in a 2005 study, nutmeg extract was found to increase desire and performance in male rats.

What about shellfish and chocolate? Surely these foods give us a boost of sexual desire? Well, yes and no. A 2005 Italian study found no difference in sexual function between women who eat chocolate daily and those who don’t. As for shellfish, a 2004 study from Italy did find that three species of Mediterranean mussels contain an amino acid that stimulates the production of hormones, including testosterone, in rats.

Does natural mean safe?

When it comes to supplements claiming to have aphrodisiac properties, “it’s buyer beware,” says Stephen Maltais, a doctor of naturopathic medicine in Port Dover, Ont. Maltais has treated sexual dysfunction in both women and men, but he cautions, “Especially if you’re buying online, you don’t know if the product is standardized for quality and quantity. However, products in Canadian stores are regulated by the NHPD [Natural Health Product Directorate], an arm of Health Canada.”

Be warned: In 2008, Health Canada issued consumer advisories about several products, including Powertabs, Viapro, Blue Steel, Rose 4 Her, Lover Liquid and Sweet Energizer Vitality Candy. All contained undeclared drugs or substances similar to those in prescription medications for erectile dysfunction. An Ayurvedic aphrodisiac, Puspadhanva Rasa, contained dangerous levels of heavy metals.

The bottom line: Do some research before you buy, and talk with your doctor before trying any of these. Sahelian adds that anyone with a medical condition, especially a heart condition, should be particularly cautious, as some herbs can raise heart rate.
