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
Many patients with moderate to severe chronic psoriasis showed significant improvement after treatment with Humira (adalimumab), according to a study presented at the recent annual meeting of the American Academy of Dermatology in Washington, D.C.
The REVEAL (Randomized Controlled EValuation of Adalimumab Every Other Week Dosing in Moderate to Severe Psoriasis TriAL) included 1,200 patients. After 16 weeks, 71 percent of the patients who took the drug showed a 75 percent improvement in skin clearance, compared to 6.5 percent of patients who received a placebo.
The study also found that patients who took the drug continuously were much less likely to experience a worsening of their psoriasis symptoms.
Upper respiratory tract infection, headache and nasopharyngitis were the most common side effects reported by patients in the study.
The REVEAL results will be submitted by drug maker Abbott in its applications to have Humira approved for treatment of psoriasis in the United States and Europe.
Psoriasis is an autoimmune disease that causes raised, inflamed, scaly, red skin lesions that can crack and bleed. There is no cure for psoriasis, which affects about 125 million people worldwide. Of those, about 25 percent have moderate to severe psoriasis. The disease can occur at any age but typically appears between the ages of 15 and 35.

Human skin is crawling with bacteria, say U.S. researchers who identified more than 200 species -- 8 percent of which were previously unknown -- on samples collected from the forearms of six people.
The New York Medical School team used genetic analysis to detect the types of bacteria present on the volunteers' skin, BBC News reported.
An initial analysis detected 182 species of bacteria. Another test was conducted eight to 10 months later to see if there had been any changes. That second analysis revealed 65 more kinds of bacteria.
About half the species were already known to be common skin dwellers, but 8 percent had not been previously described in scientific literature. The researchers also found that about 75 percent of the bacteria species were unique to individuals, which suggests the skin is "highly diversified," BBC News reported.
The findings were published online in the journal Proceedings of the National Academy of Sciences.
"Over the years maybe about 50 different organisms have been found in human skin but we knew there were more organisms present" that couldn't be detected, study leader Martin Blaser, professor of microbiology, said in a prepared statement.
"We have now gone up five-fold from what's been known before," he said.
Experts say that bacteria plays an important role in keeping skin healthy, BBC News reported.

Women are three times more likely than men to die of genital nonmelanoma skin cancer, new U.S. research shows.
Genital nonmelanoma skin cancer can be caused by sexually transmitted human papillomavirus (HPV), which is also associated with cervical cancer.
In this study, researchers found that almost 30,000 people -- 22,000 women and 8,000 men -- died of genital nonmelanoma skin cancers in the United States from 1969 to 2000.
The older a person is, the greater their risk of genital nonmelanoma skin cancer (NMSC). The findings were scheduled for presentation Sunday at the annual meeting of the American Academy of Dermatology, in Washington, D.C.
"As dermatologists, we expect to see skin cancers induced by ultraviolet light, because sunlight is one of the primary risk factors for the disease," researcher Dr. Martin A. Weinstock, professor of dermatology and community health at Brown University in Providence, R.I., said in a prepared statement.
"But some of the most dangerous types of skin cancers are those that are not sun-induced, such as skin cancers that occur on genital skin -- a place that is not exposed to intense sun and is not routinely examined by dermatologists. That's why there needs to be an increased awareness of this issue, so patients and physicians can be better prepared to detect these cancers early before they become fatal," said Weinstock, who is also chief dermatologist at Veterans Affairs Medical Center in Providence.
Because they're not always readily visible and may not cause any noticeable symptoms, genital skin cancers can be difficult to diagnose.
"The number of deaths attributed to genital NMSCs was higher than expected, and we believe HPV was a major cause of these cancers," Weinstock said.
"The availability of the new HPV vaccine offers the potential for a substantial reduction in the development of these skin cancers for future generations," he noted.
In addition, since "HPV is a sexually transmitted disease, both men and women can practice preventive measures that could lead to a decline in mortality rates from genital NMSCs and heed the warning signs of the disease, including new growths or sores that don't heal, to detect it early."

The U.S. Food and Drug Administration has ruled that the oral contraceptive YAZ can also be used by women to control moderate acne, the Associated Press reported..
The decision means that YAZ, made by Bayer Schering Pharma AG, is the first oral contraceptive to be approved by the FDA for three distinct uses, the drug maker said in a statement released Monday.
Along with birth control and acne treatment, YAZ is also approved in the United States to treat the physical and emotional symptoms of premenstrual dysphoric disorder, the AP reported.

It's a puzzle to scientists, but a new study suggests that the main cause of deadly skin cancer -- sunlight -- might also help protect against the disease.
The key could lie in the amount of ultraviolet B (UVB) light the skin absorbs -- enough to stimulate a healthy, vitamin D-linked immune response in the skin but not so much that it boosts skin cancer risk.
"I do think that a little bit of sunlight is good for people, but I think that one of the problems that the American Cancer Society and dermatologists have is, how do you define what a little bit is?" said skin cancer researcher Marianne Berwick, chief of epidemiology at the University of New Mexico's Cancer Research and Treatment Center. "How do you tell people that it's OK to have a little bit of sunlight but not too much?"
In 2005, Berwick's team published a controversial study that found that melanoma patients with higher levels of daily sun exposure actually had better survival than patients who spent less time in the sun.
"I've been searching for an explanation for that ever since," she said.
Now, findings from a group led by immunologists at Stanford University may provide an answer. The study, led by professor of pathology Eugene Butcher, is expected to be published in the March issue of Nature Immunology.
In its study, the Stanford team worked with cells in the lab and discovered a biochemical chain of events that appears to link sunlight exposure to the skin's own immune defenses.
The researchers started from the notion that an inactive precursor of vitamin D, called vitamin D3, "is generated in the skin in response to sun exposure." That's been known for years. Specifically, a short-wavelength form of UV light, called UVB, is responsible for D3 generation.
D3 is inert and powerless, however. Through contact with various enzymes in the liver and kidneys, the body turns D3 into an active compound called 1,25(OH)2D3.
And that's where the immune-system connection kicks in, the Stanford authors said.
In their experiments, they found that the new compound "signaled (immune) T-cells," pushing them to migrate back to specific sites in the skin's epidermis. Once there, these powerful immune system agents stand on guard against infection and even cancer, the researchers said.
"So, the same wavelengths of sunlight that are most potent in inducing skin cancer -- UVB -- are also the wavelengths that produce this vitamin D precursor, D3," said Dr. Martin Weinstock, chairman of the skin cancer advisory group at the American Cancer Society. And it's D3 that starts the whole chain of events rolling.
Weinstock stressed that the Stanford study is far from conclusive, however, and should not be seen as an excuse to bake in the sun.
"We know that the sun is the major avoidable cause of skin cancer," he said. "This study is interesting and points to a productive area of research, both to confirm this in other settings and to flush out the implications of the finding. But does it really relate to skin cancers in real live people? We don't know."
"So, avoiding intense sun, protecting yourself when you're out in intense sun -- that's still our [cancer society] recommendation, and this is not going to change that," said Weinstock, who is also professor of dermatology and community health at Brown University.
Kathleen Egan, a professor of epidemiology at the H. Lee Moffitt Cancer Center and Research Institute in Tampa, Fla., agreed that the study findings are "tantalizing" but need further study.
Especially since the release of Berwick's melanoma study, "there's been an awful lot of questions about how -- or if -- vitamin D has a part to play in potentially offering some [cancer] protection under some circumstances," she said. "But it's very difficult to tease out, because the main human source of vitamin D is, in fact, sunlight exposure, which is also the most important risk factor for melanoma."
Nutritionists have known for decades that sunlight stimulates vitamin D production in the skin. In fact, this natural process is the body's major source of the nutrient. A proper amount of vitamin D is crucial to bone health, "and there's also a bunch of evidence that vitamin D may have a role in preventing colon cancer, although there's still some controversy about that," Weinstock said.
So, how much sunlight is enough to get the ideal amount of vitamin D?
Katharine Tallmadge, a Washington, D.C., dietitian and a spokeswoman for the American Dietetic Association, suggests that most people can probably get the U.S. Department of Agriculture's recommended 400 daily IUs of vitamin D by spending a half-hour to an hour outside per day.
Egan agreed. She said it's not difficult for people to soak up the sun's goodness without boosting their cancer risk. In response to even a moderate amount of sunlight, "the skin actually creates an amazing amount of vitamin D," Egan said. "It doesn't take much exposure to make enough of the vitamin D that's certainly needed to preserve bone health, for example."

Two are better than one when it comes to performing a skin exam for melanoma and spotting it at the earliest, most treatable stage, a new study shows.
Men and women at high risk of developing melanoma who underwent skin self exam training with their live-in partner were more likely to perform the exams than those who trained solo, Dr. June K. Robinson of Northwestern University Feinberg School of Medicine in Chicago and colleagues found.
People trained to perform a skin self exam also seek treatment at an earlier stage of melanoma and are less likely to die from it, Robinson and her team note in the Archives of Dermatology. They hypothesized that training couples in skin self exams would be even more effective than training individuals because couples may encourage each other to do the exams and help each other another to perform them.
To investigate, Robinson's group randomly assigned 130 people to undergo a 10-minute training on skin self exams alone or with their live-in partner.
Four months after the training, 45 of the 65 people who underwent solo training had not examined their skin, compared with 23 of the 65 who trained with their partner. Of the paired learners, 19 checked their skin at least once and 13 checked it several times, compared with 9 and 4 of the solo learners, respectively.
The men and women who learned in pairs also were more likely to perceive the exams as important and to feel confident in their ability to perform the exams, the researchers found.
The study "affirms the role of partners in health care and extends it to promoting health behaviors," the researchers conclude.
