Drinking two cups of spearmint tea a day might help treat women with an unsightly condition that causes them to grow excess hair on their face, breasts and stomach, Turkish researchers report.
The tea works by lowering the levels of circulating male hormones in these women, the scientists claim in the current online issue of Phytotherapy Research.
The authors called the findings preliminary.
"There are no recommendations for patients and physicians yet," said Mehmet Numan Tamer, co-author of the study and a professor of endocrinology and metabolism at Suleyman Demirel University in Isparta, Turkey. "This is the first clinical study about the spearmint tea, but further studies are needed to give the practical recommendations to patients."
But other experts feel the findings are far-fetched.
"This is absurd," said Khursheed Navder, an associate professor of nutrition and food science at Hunter College in New York City. "I completely think it is very preliminary, and you need major randomized trials. It's nothing to get thrilled about."
Hirsutism is a condition that can occur in both men and women, but, for obvious reasons, it is more of a cosmetic concern in women. The hair growth is a result of unnaturally high levels of androgens such as testoserone.
According to Tamer, standard therapy includes oral contraceptives to suppress androgens or drugs such as spironolactone, which prevents the body responding to androgens.
Spearmint, which grows naturally near Isparta, has been widely used for indigestion, nausea and vomiting, as well as for the common cold, cough, sinusitis, fever and bronchitis.
"Spearmint has been used as an herb for a long time now," confirmed Navder. "These are all folk remedies."
The Turkish researchers thought that spearmint might be linked with reports of diminished libido in townsmen (presumably because of its effects on androgen levels). In one previous rat study, spearmint reduced testosterone levels.
"Previously, we investigated the effects of [peppermint] and [spearmint] herbal teas on testicular function in an experimental rat model and found that testosterone levels were decreased," Tamer said. "Because we found the anti-androgenic effects of spearmint, we decided to observe the effect of this herbal tea on the androgen levels in hirsute women."
For this study, 21 women with hirsutism drank two cups of herbal spearmint tea for five days at a certain time in their menstrual cycle.
All women showed a decrease in free testosterone (circulating hormone not bound to other molecules) and an increase in several different "female" hormones, including follicle-stimulating hormone and estrogen.
There was no significant decrease in total testosterone levels; it was unclear if there was any change in amount of excess hair growth.
"The next step is to show the effect of spearmint tea on hirsutism scores of the women in a treatment period," Tamer said.
Although the amounts of spearmint used in this study are not generally toxic, the herb can be harmful if taken in larger amounts

Black tea eases stress by lowering blood levels of the stress hormone cortisol, says a British study in the journal Psychopharmacology.
The six-week study of 75 people found that those who drank black tea were able to de-stress more quickly than those who drank a caffeinated tea substitute, BBC News reported.
The participants were assigned challenging tasks while their cortisol, blood pressure, blood platelet, and self-rated levels of stress were measured by the researchers. During these tasks, both groups of study participants experienced large increases in blood pressure, heart rate, and self-rated levels of stress.
However, 50 minutes after the stressful tasks, cortisol levels dropped by an average of 47 percent among those who drank black tea and 27 percent among those who drank the tea substitute.
The study also found that the tea drinkers had lower blood platelet activation, which is associated with blood clotting and heart-attack risk, BBC News reported.
It's unclear which ingredients in black tea help reduce stress, the University College London researchers said.

To arrest rising health-care costs, a growing number of U.S. employers are expanding workplace "wellness" initiatives. Providing workers with tools and incentives to improve their health, the thinking goes, will reduce medical-care costs and boost worker productivity.
Experts say it's a trend that bodes well for employees who are motivated to lose weight, quit smoking, manage a chronic condition or just stay fit.
"Pretty clearly, employers have realized that if they're going to manage benefit costs and manage work loss, they need to get at the underlying health drivers of that -- employee health -- and get at the root causes of health-care utilization and health-care expenditures," said Bruce Kelley, practice leader for data services in the Minneapolis office of Watson Wyatt Worldwide, a human resources consulting firm.
According to Kelley, employers have been investing much more heavily in wellness services in the last few years. "I've been consulting in this area for 20 years," he noted, "and I've never seen as much activity among employers as I've seen just in the last few years."
Wellness is a broad term that describes the panoply of health-management services that companies offer, from onsite fitness centers and smoking-cessation classes to health-risk appraisals and disease-management programs.
Survey data show that more large employers are offering programs to improve employee health and productivity. Seventy-five percent offered a "health promotion" program in 2005 or 2006, up from 56 percent in 2003, according to survey results released last December by Watson Wyatt and the National Business Group on Health.
Nearly three out of four employers (72 percent) are sponsoring health-risk appraisals to measure individual employees' health risks and behaviors. And 40 percent are engaging "personal health coaches," health professionals who can help, say, an employee with diabetes manage their diet, exercise and drug regimens.
At the same time, corporate America and public health leaders are grappling to understand which particular interventions or combinations of programs and incentives yield the greatest return on investment.
"There has not been a tremendous amount of high quality research in this area," said Doug Evans, director of the Center for Health Promotion Research at RTI International, a nonprofit research institute based in Research Triangle Park, N.C.
But there are a number of efforts under way to learn what works. The U.S. Centers for Disease Control and Prevention, for one, is sponsoring a series of studies to evaluate worksite efforts to prevent and control obesity.
In one study, published in the September/October 2005 issue of the American Journal of Health Promotion, CDC and RTI researchers found that obesity boosts employers' costs, including medical expenditures and absenteeism, by $460 to $2,500 per obese employee per year. They estimated that the cost of obesity at a firm with 1,000 employees is about $285,000 per year.
In March, the National Business Group on Health issued 10 recommendations for promoting prevention in the workplace. Overall, it concluded that without the support of top-level management, companies cannot convey "the importance to employees of caring for themselves."
Some employers are using incentives to get workers on the wellness bandwagon. You might qualify for a lower health insurance premium, say, if you stop smoking, or you could earn a $25 gift certificate for completing a health-risk appraisal.
The use of incentives will continue, Evans predicted. However, he believes employers must do a better job of promoting the benefits of health, much like anti-tobacco advocates did by portraying a non-smoking lifestyle as cool, hip and fun.
"Maybe that kind of technique can be effective in obesity," he offered. "Can you make it cool to be healthy weight and not to be fat?"
Arkansas Gov. Mike Huckabee, chairman of the National Governors Association, is encouraging all Americans to live healthy lifestyles through a national campaign, Healthy America: Wellness Where We Live, Work and Learn.
