Could lavender and tea tree oil act as endocrine disruptors?
ABC SCIENCE ONLINE
The lavender and tea tree oils found in some soaps, shampoos, hair gels and body lotions can produce enlarged breasts in boys, researchers report.
These plant oils were linked to abnormal breast development in three boys, which was reversed when they stopped using them, write Dr Clifford Bloch of Pediatric Endocrine Associates in Colorado, and colleagues.
They say their study, published today in the New England Journal of Medicine, suggests these oils can act in ways similar to the hormone estrogen.
"This report raises an issue of concern, since lavender oil and tea tree oil are sold over the counter in their 'pure' form and are present in an increasing number of commercial products, including shampoos, hair gels, soaps, and body lotions," the researchers write.
"Whether the oils elicit similar endocrine-disrupting effects in prepubertal girls, adolescent girls, or women is unknown."
While it is very common for boys to develop temporary breast enlargement as they go through puberty, the condition is very rare in young boys.
Doctors call the condition prepubertal gynaecomastia, and often find no explanation for it.
The researchers found the condition in three otherwise healthy boys, aged 4, 7 and 10.
"I got wind of it because I was given a clue by a patient," Bloch says.
That case involved the 4-year-old "who was using absolutely nothing on his skin except a lavender oil preparation that his mother had obtained from a homeopath. She used to rub it on his chest and body every night" because lavender, in complementary medicine circles, is said to have healing properties.
Several months after the boy stopped getting the 'healing balm', his breasts returned to normal.
Meanwhile, Bloch then began to see lavender crop up in other cases, including the 10-year-old, who was using a hair styling gel and shampoo that contained both lavender oil and tea tree oil.
There was also a 7-year-old, who had been using lavender-scented soap and skin lotions.
In laboratory tests, scientists at the US National Institute of Environmental Health Sciences (NIEHS) found that both substances can mimic the action of the female hormone estrogen.
They can also block male hormones that control both masculine characteristics and inhibit the growth of breast tissue.

CANCER-CAUSING CHEMICAL FOUND IN CHILDREN'S BATH PRODUCTS
Women’s
Shampoos and Body Wash also Contaminated
WASHINGTON — A hidden cancer-causing
petrochemical has been found in dozens of children’s bath products
and adults’ personal
care products, in some cases at levels that are more than twice the
U.S. Food and Drug Administration’s lenient recommended maximum.
Laboratory tests released today revealed the presence of 1,4-Dioxane
in products such as Hello Kitty Bubble Bath, Huggies Baby Wash, Johnson’s
Baby Wash, Scooby-Doo Bubble Bath and Sesame Street Bubble Bath.
The tests also found the carcinogen in Clairol Herbal Essences shampoo,
Olay Complete Body Wash and many other personal care products. 1,4-Dioxane
is a petroleum-derived contaminant considered a probable human carcinogen
by the U.S. Environmental Protection Agency and a clear-cut animal
carcinogen by the National Toxicology Program. It is also on California’s
Proposition 65 list of chemicals known or suspected by the state
to cause cancer or birth defects. Because it is a contaminant produced
during manufacturing, the FDA does not require it to be listed as
an ingredient on product labels.
The problem of 1,4-Dioxane contamination
in personal care products is highlighted in a new book, “Safe Trip to Eden: Ten Steps
to Save the Planet Earth from the Global Warming Meltdown,” by
David Steinman. The laboratory results were released jointly today
at the National Press Club by Steinman and the Campaign for Safe
Cosmetics, a coalition of U.S.-based health and environmental groups
working to protect cosmetics consumers from toxic chemicals and hold
companies accountable for the safety of their products.
“Regrettably, 1,4-Dioxane contamination
is just the tip of the iceberg,” said Jeanne Rizzo, R.N., executive
director of the Breast Cancer Fund, a founding member of the Campaign
for Safe Cosmetics. “Because the FDA does not require cosmetics
products to be approved as safe before they are sold, companies can
put unlimited amounts of toxic chemicals in cosmetics.” Steinman
said parents should be outraged that companies are willing to spend
a significant amount of money on entertainment licensing agreements
that entice children but won’t spend pennies to
remove contaminants such as 1,4-Dioxane. “Consumers who have
young children, as I do, have the right to expect the highest purity
in children’s products,” Steinman
said. “I call on American consumers to say no to dangerous
petrochemicals in their children’s cosmetic and personal care
products.”
Contrary to what many consumers may believe,
the FDA does not review or regulate cosmetics products or ingredients
for safety before they are sold to the public and has no legal authority
to require safety assessments of cosmetics. Devra Lee Davis, professor
of epidemiology and director of the Center for Environmental Oncology
at the University of Pittsburgh Cancer Institute, said that the usual
regulatory approach of assessing risk one chemical at a time does
not account for the combined effects of very low levels of hidden
contaminants in personal care products and from other sources. “We
must lower exposures to controllable agents that we know or suspect
cause cancer,” she said.
The FDA has been measuring 1,4-Dioxane levels
since 1979, but because the agency has little authority or enforcement
capacity over the cosmetics industry, it has worked with manufacturers
to reduce levels on a voluntary basis only. In 2000, the FDA recommended
that cosmetic products should not contain 1,4-Dioxane at concentrations
greater than 10 ppm (parts per million); yet some 15 percent of products
tested exceeded even these lenient guidelines. This limit, however,
also does not take into account that babies exposed to 1,4-Dioxane
from baby shampoo may be exposed at the same time to 1,4-Dioxane
from bubble bath, body wash and many other products. More than two
dozen products were tested at Steinman’s request
by West Coast Analytical Service, an independent testing laboratory
specializing in trace chemical analysis. Among the products tested:

Worry Free Luxury means we don't use Lavender
or Tea Tree Oils!
Due to recent scientific findings The Original Little Sprout does
not use lavender or tea tree oil in their products.
Scientists discovered that gynecomastia, a condition in which boys
develop breasts, is caused by using estrogen enhancers such as as
tea tree oil and lavender. |

Personal-Care Products Can
Spur Breast Development in Boys
Tea tree oils and lavender produce a condition
called gynecomastia,
study finds.
WEDNESDAY,
June 28 (HealthDay News) -- Personal-care products containing tea
tree oils and lavender appear to cause abnormal breast development
in pre-pubescent boys, a new study found. The ingredients, which
have an estrogen-like effect, are found in various shampoos, lotions,
soaps and other products. "There's definitely an association
between exposure to lavender oil and tea tree oil and gynecomastia
[abnormally large breasts in men]," said Derek Henley, lead
author of the research and a postdoctoral fellow at the National
Institute of Environmental Health Sciences, in Research Triangle
Park, N.C. Henley stopped short of declaring a cause-and-effect relationship,
but did emphasize that the information could help physicians identify
cases of gynecomastia that have no readily apparent cause. "It
may help steer physicians in a direction they wouldn't have thought
of," Henley said. "The message is to raise
awareness, so the public is aware of the association, and physicians
are aware of it," he said. Dr. Edward Reiter, chairman of pediatrics
at Bay State Children's Hospital in Springfield, Mass., added, "The
issue is a Sherlock Holmes kind of thing. This was a pretty good
pick-up. It's old-fashioned science sleuthing. You have a problem,
and you figure out what's going on." Henley presented the findings
at the just-completed annual meeting of the Endocrine Society, in
Boston. Reiter was moderator of a press conference announcing the
findings. Gynecomastia is associated with an imbalance of estrogens
(so-called female hormones) and androgens (so-called male hormones).
Young boys don't produce much testosterone, so there is nothing in
the body to counteract extra estrogen, such as might come from mistakenly
taking a mother's birth control pill or, more concerning, an estrogen-secreting
tumor. The condition is unusual. "I may see a patient every
year or every other year with this, a pre-pubertal boy who has some
breast development," Reiter said. "Usually, it's a tiny
amount, and you never find out what it is, then it goes away," he
explained. But when Dr. Clifford Bloch, co-author of the study and
a pediatric endocrinologist in Denver, saw five boys with the problem,
he decided to investigate. All of the boys, he soon realized, had
used over-the-counter health-care products containing lavender and/or
tea tree oil on their hair or skin.When tested on human breast cancer
cells, the oils appeared to mimic the activity of estrogen and also
suppressed male hormone responsiveness. After discontinuing use of
the lavender and tea tree oils, all of the boys saw the problem resolved.
And even though the condition is relatively uncommon, experts think
this information will help clear other "mystery" cases."My
guess is that this sort of thing occurs in a scattered way in little
boys all the time," Reiter said. "It may
well be that someone wouldn't even think of this. Now, doctors can
ask if the patient is using any products," he said.The American
Academy of Family Physicians has more on gynecomastia.

Headteaching, pharmacy and hairdressing are three jobs carrying an
increased risk of breast cancer, according to a Swedish study
The survey, of more than a million women revealed these inexplicable
patterns, also implicating systems analysts, beauticians and telephone
operators as having a higher than normal risk.

Writing in the
American Journal of Public Health, Dr Marina Pollan and Dr Per Gustavsson
said that some of the statistical blips might be due to the career
paths followed by white collar workers. The study's authors speculated
that exposure to chemicals used in the hair and
beauty industry might contribute to the extra risk.
Currently, one in 12 British women and one in eight US women will
get the disease at some point in their lives. |

What
Are PARABENS?
Preservative chemicals found in samples of breast tumours probably
came from underarm deodorants, UK scientists have claimed. Their analysis
of 20 breast tumours found high concentrations of para-hydroxybenzoic
acids (parabens) in 18 samples. Parabens can mimic the hormone estrogen,
which is known to play a role in the development of breast cancers.
The preservatives are used in many cosmetics and some foods to increase
their shelf-life. "From this research
it is not possible to say whether parabens actually caused these tumours, but
they may certainly be associated with the overall rise in breast cancer cases," says
Philip Harvey, an editor of the Journal of Applied Toxicology, which published
the research. "Given that breast cancer is the largest killer of women and
a very high percentage of young women use underarm deodorants, I think we should
be carrying out properly funded, further investigations into parabens and where
they are found in the body," Harvey told New Scientist. |

What
Are SULFATES?
Most hair products that contain sulfates, which are caustic chemicals
and cannot be washed off our bodies with water they actually penetrate
the skin-barrier and are absorbed into our tissues. This absorption
process can cause the sebum of the hair shaft to become crystallized,
effectively closing the hair follicle. The resultant induction of skin
tightness of the scalp severely reduces life-giving blood flow to the
hair follicle! Over a period of time the crystallized sebum prevents
the re-growth of healthy hair. As a further result of this damage by
chemical emulsifiers the hair follicles itself deteriorates and can
no longer produce hair! The result is thinning and receding hairlines
in both men AND women.
Our Children’s Collection Natural Shampoo used regularly instead
of, any sulfates, olefin sulfate, parabens, DEA, artificial colors & Dyes-
the scalp environment is enriched and the body responds by "healing
itself". A hair follicle can stay "alive" for
up to ten years without a hair growing from it. Therefore,
our Original Little Sprout Children’s Shampoo will help
to make hair grow, but in reality we have simply found an all-natural
way to remove the offending ingredients that have been proven to CAUSE hair
loss. In addition, hair loss caused by chemicals will stop within a
few short days and your scalp will return to its normal healthy state! |
