Alcohol's health benefits doubted

Any heart gains from drinking alcohol in moderation are likely outweighed by the harm, say researchers.

The findings in The Lancet suggest that drinking a glass or two of wine a day may not be such a good idea.

Although past research suggests some heart benefits, the New Zealand team says the studies were flawed.

Indeed, there is more evidence that heavier drinking provides the most heart protection - alcoholics have relatively 'clean' arteries - they say.

Vitamin D 'can lower cancer risk'

High doses of vitamin D can reduce the risk of developing some common cancers by as much as 50%, US scientists claim.

Researchers reviewed 63 old studies and found that the vitamin could reduce the chances of developing breast, ovarian and colon cancer, and others.

Experts said more research was needed to draw firm conclusions.

Cancer team make 'super-broccoli'

Is it a bird? Is it a plane? NO! It's super broccoli!

Scientists are developing a "super-broccoli" which they hope will help people ward off cancer.

Broccoli has anti-cancer properties but an Institute of Food Research study has found some people's genetic make-up may minimise the protection they get.

IFR scientists say creating broccoli containing more of the key chemical - sulforaphane - may counter this effect.

They hope it will be ready in three years but recommend eating lots of different green vegetables until then.

High-veg diet 'wards off cancer'

Chinese medicine outlets probed

A recent BBC investigation has found that scores of traditional Chinese medicine stores in Britain's high streets are being investigated for selling illegal medicines. The BBC discovered that 67 outlets selling Chinese medicines are under suspicion.

It is estimated that 6,000 stores across the country offer treatment for conditions ranging from eczema to the menopause. But the industry, although growing in popularity, is largely unregulated.

At the Herb Garden store in Leigh on Sea, Essex, an undercover reporter from the BBC was sold a herbal slimming pill and told it contained rhubarb and honeysuckle. Tests showed it contained fenfluarmine - an illegal pharmaceutical considered to be so dangerous that it is banned in most countries worldwide, including the UK.

The owner of the store was prosecuted earlier this year for illegally selling the same drug. She was fined £30,000 with another £20,000 in court costs. The maximum sentence for selling an illegal medicine is two years imprisonment.

The US work in the Journal of the National Cancer Institute applies to about 30% of breast cancers.

Star Anise - the world's last hope against bird flu?

Seemingly star anise, from which the drug Tamiflu is made, may be the only defense the world currently has against an avian flu pandemic.

The Independent, claims the herb star anise is the world's only weapon against the deadly disease bird flu. It says a shortage of the herb means Britain cannot produce enough of the drug Tamiflu to protect the public. Only star anise grown in the four provinces of China is suitable for manufacture into Tamiflu and 90 per cent of the harvest is already used by Roche.

A derivative of star anise, shikimic acid, is used in production of the drug Tamiflu (Oseltamivir Phosphate), which is said to reduce the severity of avian flu. The star anise from which Tamiflu is made is only grown in four provinces in China and "huge quantities" of its seeds are needed, according to the Swiss pharmaceutical manufacturer Roche. It is harvested for this purpose between March and May, purified and the shikimic acid extracted at the start of a 10-stage manufacturing process, which takes a year.

The Guardian says veterinary experts want the government to stockpile the vaccine to combat the disease's spread.

The Daily Telegraph says the Tories and Liberal Democrats claim stocks should have been amassed sooner.

Anti-HIV drug from rainforest almost lost before its discovery

Rainforest plants have long been recognized for their potential to provide healing compounds. Indigenous peoples of the rainforest have used medicinal plants for treating a wide variety of health conditions while western pharmacologists have derived a number of drugs from such plants.

However, as forests around the world continue to fall -- the Amazon alone has lost more than 200,000 miles of forest since the 1970s -- there is a real risk that pharmaceutically-useful plants will disappear before they are examined for their chemical properties. Increasingly, it is becoming a race against time to collect and screen plants before their native habitats are destroyed. One near miss occurred recently with a compound that has shown significant anti-HIV effects, Calanolide A.

Calanolide A is derived from Calophyllum lanigerum var austrocoriaceum, an exceedingly rare member of the Guttiferae or mangosteen family. Samples of Calophyllum lanigerum var austrocoriaceum were first collected in 1987 on an National Cancer Institute (NCI)-sponsored expedition in Sarawak, Malaysia on the island of Borneo. Once scientists determined that Calophyllum lanigerum var austrocoriaceum showed activity against HIV, researchers returned to the original kerangas forest near Lundu (Sarawak, Malaysia) to gather more plant matter for isolating the active compound. The tree was gone -- likely felled by locals for fuelwood or building material. The disappearance of the tree lead to mad search by botanists for further specimen. Good news finally came from the Singapore Botanic Garden which had several plants collected by the British over 100 years earlier. Sarawak banned the felling and export of Calophyllum shortly thereafter.

Acupuncture is effective against osteoarthritis

A new study published in the British Medical journal suggests that acupuncture as a complementary therapy to drug treatment for osteoarthritis of the knee, is more effective than drug treatment alone.

A total of 88 patients with osteoarthritis of the knee were randomly divided into two groups, one receiving acupuncture plus diclofenac (an anti-inflammatory drug) and the other dummy (placebo) acupuncture plus diclofenac.

Treatment lasted 12 weeks and levels of pain, stiffness, and physical function were monitored using recognised scales. The acupuncture group had a greater reduction in pain and stiffness, improved physical functioning and quality of life than the placebo group.

Although the 12-week monitoring period may be insufficient to evaluate the effects of treatment in the medium term, acupuncture as a complementary therapy to drug treatment for osteoarthritis of the knee is more effective than drug treatment alone, say the authors.

Cranberries can fight tooth decay

Get ready to pamper your taste buds and protect your teeth against decay at the same time as a new research has revealed that cranberries are an important weapon in fighting tooth decay.

The British Dental Health Foundation (BDHF) has said that cranberries can prevent a host of oral health problems, including gum disease and tooth decay.

Following up on a research carried out by the University of Rochester in New York, the BDHF discovered that cranberry juice stopped harmful bacteria sticking to the teeth. Cranberry juice also ensures that plaque never gets a chance to form.

"Cranberry juice is naturally very acidic. Every time you drink something acidic the enamel on your teeth is softened temporarily.If given time to recover, then your saliva will neutralise this acidity in your mouth and restore it to its natural balance,"Dr Nigel Carter, chief executive of the British Dental Health Foundation, was quoted by the Daily Mail, as saying.

However, the researchers have cautioned that the intake of cranberries should be limited to only the meal times as its excess can have some harmful effects.

"However, if this attack happens too often the mouth does not have the chance to repair itself and tiny particles of enamel can be brushed away. This is called erosion. Erosion can cause pain and sensitivity in the teeth, and once the enamel has worn away can also leave your teeth open to decay too - so try to keep cranberry juice to mealtimes only," he added.

Herbal remedies do have 'real benefits

Researchers from King's College in London have said that scientific tests on a range of herbal remedies have shown that they do have 'real benefits'.

The researchers said that herbal treatments from around the world had properties, which may help treat conditions such as diabetes and cancer.

The researchers examined Indian diabetes treatments, Ghanaian wound healing agents and cancer treatments used in China and Thailand.

One of the plants examined was the curry-leaf tree (Murraya koenigii) from India, which is reputed to have potential benefits in treating diabetes.

The researchers discovered that extracts from the curry-leaf tree appeared to restrict the action of a digestive enzyme called pancreatic alpha-amylase, which is involved in the breakdown of dietary starch to glucose. They are now looking at which compound in the curry-leaf tree has this effect, and claim that once it is identified, it should be possible to evaluate if it could be better than existing anti-diabetic drugs.

The researchers while working with experts from the Kwame Nkrumah University of Science and Technology, Ghana, also looked at plants used by the Ashanti ethnic group.

They found that an extract of the Commelina diffusa, or climbing dayflower, had both antibacterial and anti-fungal activity, which could help heal wounds and also stop them getting infected.

In a third study, the researchers studied Thai and Chinese plants used as traditional remedies in the treatment of cancer, and found promising activity against lung cancer cells, particularly in tests of the Thai plant Ammannia baccifera, an aquatic weed and the Chinese plant Illicium verum, star anise.

"This research is very interesting, very promising. We need much more research of this sort. More and more research of this kind is coming out. It is no surprise to those who work in this field," the BBC quoted Edzard Ernst, professor of complementary medicine at the Peninsula Medical School in Exeter, as saying.

Women searching for ways to ward off the anxiety and irritability caused by premenstrual syndrome may be able to find answers as nearby as their local supermarket.

A study published Monday finds that a diet rich in calcium and Vitamin D -- available in milk, cheese, yogurt and fortified orange juice -- appears to help women reduce the risk of PMS symptoms.

The findings support earlier research indicating calcium seems to help women cope with PMS. But the new study also suggests that when calcium is combined with enough vitamin D, it may help prevent PMS altogether.

"It seems that women who eat more foods high in calcium and vitamin D have less risk of experiencing PMS," said the study's lead author, Dr. Elizabeth Bertone-Johnson of the University of Massachusetts. "It's very exciting, and could end up being good news for many women out there."

She said, however, that the research is too preliminary to recommend diet changes for women in general and that more thorough studies are needed.

Egyptians ate lettuce to boost sex drive

The ancient Egyptians used lettuce as an aphrodisiac, according to an Italian researcher who claims to have solved a century-old archaeological puzzle.

Lettuce has been known for its mild sedative and painkilling effects since Greek and Roman times.

It owes its Latin name lactuca to lac or milk, the plant's bitter white sap or latex, which is mentioned in many ancient treatises.

As early as 430 BC, Greek physician Hippocrates described the opium-like effects of the sap.

And according to Dioscorides Pedanios, a Greek naturalist and military surgeon to the armies of the Roman emperor Nero in the 1st century AD, lettuce would drive out libidinous images of dreams.

Pliny the Elder, in the 2nd century AD, also wrote about lettuce's ability to dampen sexual desire. He wrote in his Natural History that lettuce is "sleep-inducing, can cool sexual appetite as well as a feverish body, purge the stomach, and increase the volume of blood".

Yet Egyptian bas reliefs put a different spin on the use of lettuce: the plant appears as an offering to the ancient Egyptian deity Min.

Invariably depicted with a large, erect penis, Min was the god of fertility and sexuality. For more than a century, archaeologists have wondered why a vegetable used to calm dreams was associated with the exuberant Min.

Sun 'cuts prostate cancer risk'

Sunlight can reduce a man's risk of prostate cancer, a study suggests.

Researchers from three US centres found men exposed to a high amount of sun had half the risk of the disease than those exposed to a low amount.

Writing in Cancer Research, they suggest that the protection was a result of the body's manufacture of vitamin D after sun exposure.

But men were warned not to sunbathe excessively because of the risk of developing skin cancer.

Vitamin D is also found in foods such as oily fish.

Potato health benefits discovered

Potatoes may be healthier to eat than previously thought, after scientists found them to contain chemicals which lower blood pressure.

'Avoid soya if you want a baby'

Women should avoid eating too much soya if they are trying for a baby, a UK fertility expert believes.

Cancer hope for green tea extract

My second favourite beverage (after coffee) is proving its worth once again as reported by the BBC:-

A chemical extracted from green tea could help scientists to develop new drugs to fight cancer.
Tests by UK and Spanish researchers showed polyphenol EGCG taken from green tea leaves inhibits cancer cell growth.

The effect was seen even at low concentrations, equivalent to drinking two or three cups of green tea a day.

However, the study, published in Cancer Research, also found high concentrations of the chemical may increase the risk of birth defects.

Previous research has suggested that drinking green tea helps to cut the risk of certain forms of cancer.

The latest study found that EGCG binds to a key enzyme - dihydrofolate reductase (DHFR) - that is targeted by established anti-cancer drugs.

This stops the enzyme from triggering the manufacture of new DNA in tumour cells.

It appears to work in the same way as the cancer drug methotrexate - but in practice would probably have fewer side effects.

A herb in the balance

Two years ago, the UK government banned kava, a herbal remedy for treating anxiety. A suspicion had emerged that it might cause liver damage. The ban incensed proponents, some of whom decided to take the government to court over the matter. Now the Medicines and Healthcare products Regulatory Agency (MHRA) is reconsidering the decision; the organisation has recently invited interested parties to submit new evidence.

Kava is a plant (Piper methysticum) from the South Sea, where it has been used as a medicine for centuries. Rigorous clinical trials over the past two decades have demonstrated that it is effective in reducing anxiety. Kava therefore had become very popular. But the "kava-boom" came to a halt when cases of severe liver problems emerged. Eighty-four cases have now been associated with kava worldwide. Nine patients have suffered irreversible liver failure, and six individuals have died. None the less, proponents, including those organised in the International Kava Executive Council, insist that the evidence is inconclusive, pointing out that such adverse effects are extremely rare - only about one case per 50 million kava users.

Several new theories might explain what is really going on. In most of the cases, experts identified other possible causes for the liver damage. Many of the affected patients also consumed alcohol or took drugs known to damage the liver. The other patients could have suffered from liver conditions related to diseases such as infectious hepatitis. And some people will always experience liver problems apparently out of the blue.

Another theory holds that the modern manufacturing process for kava supplements is to blame. Natives from the South Sea make their kava drink essentially by dissolving the root in water. Kava supplements, however, are extracted with solvents which take out toxic constituents from the plant which are absent in the traditional kava drink. New evidence suggests that habitual kava users in the South Sea show no signs of liver problems even though they take rather high doses.

Other experts suspect that the huge popularity of kava supplements created so much demand that people started processing parts of the plant that were never meant to be used. This mistake, they think, led to products with toxic constituents not normally contained in quality products. This theory could explain why kava was used for such a long time without problems, and only when sales boomed did problems emerge.

Finally, some researchers believe that there could be a genetic explanation. Natives of the South Sea might be protected from liver damage simply because they are genetically different from us. In fact, the vast majority of Caucasians have nothing to fear. According to this school of thought, only a very small group of people afflicted with a genetic abnormality are at risk.

Meanwhile, three new clinical trials confirm the effectiveness of kava in relieving anxiety, which brings the total number of trials to 12. Several independent experts are now sure that the benefits of kava outweigh its risks. They also point out that conventional drugs with similar anxiolytic properties, such as Valium, are at least as harmful as kava.

In the coming months, the kava debate is set to reignite. The MHRA has already stated that kava poses "a rare but serious risk to public health". The First International Kava Conference, which took place in December 2004 in Fiji, arrived at the opposite conclusion: "We see no grounds for continuing bans and restrictions [and] call for their immediate removal."

The rest were given a Duxil, (almitrine + raubasine), a drug which increases oxygen use in brain tissue. It has previously been shown to improve the memory of elderly patients with dementia.
All 40 were given memory tests which focused on how well they could recall stories, words and other verbal and visual memory tests before and after the 12-week study.

Those given the ginseng significantly improved their average memory function after 12 weeks.
It was found ginseng increased the activities of the brain chemicals acetylcholine and choline acetyltransferase in elderly mice.

Herb 'as good as depression drug'

A German study has added weight to the argument that a herbal remedy is an effective treatment for depression.

Researchers compared the effectiveness of St John's wort to anti-depressant drug paroxetine in treating moderate and severe depression.

The team found half of those with the condition improved when given the herb, compared with a third using the drug, the BBC News

Pet therapy 'helps schizophrenia'

Pet therapy can help people with schizophrenia feel more motivated and improve their quality of life, research has suggested.

A team from the Technion Institute of Technology in Israel looked at the effect of bringing dogs into therapy sessions.

Patients in these sessions were much less apathetic compared to those who underwent conventional therapy.

The study is published in Psychotherapy and Psychosomatics.

Could cabbage prevent cancer?

Researchers at Cardiff University want to find out if a substance found in vegetables like cabbage and sprouts could ward off cervical cancer.

They need 3,000 volunteers for the study on the effects of the chemical- diindolylmethane (DIM) - which is sold as a food supplement.

Cancer Research UK is funding the trial.

Vitamin warning for liver lovers

People should limit eating liver to once a week and be careful about other sources of vitamin A, say food experts.

Too much is toxic and increases the risk of bone fractures, according to advisers to the Food Standards Agency.

Combining supplements with vitamin A-rich foods such as liver is particularly risky, the Scientific Advisory Committee on Nutrition says.

Post-menopausal women and older people at highest risk of fractures should not have more than 1.5mg per day, it says

African herb yields its anti-addiction secret

THE secret of an African herb that helps drug addicts and alcoholics kick the habit has been discovered. The finding could lead to safer and more effective medications for treating addiction.

Since the 1960s, many addicts have reported that even a single dose of ibogaine, a hallucinogenic alkaloid extracted from the root of an African shrub, helps them kick their habit by reducing their cravings for drugs. And there is hard evidence to back these claims, as well. However, troubling side effects - including heart problems and several deaths - have kept ibogaine from being widely accepted as a medical treatment. Instead, a few researchers have begun searching for ways to deliver ibogaine's benefits without its risks.

Camomile tea for aches and ills

Drinking camomile tea can fight a cold and banish menstrual cramps, UK researchers believe.
Five cups a day for a fortnight is enough to boost urine levels of substances that can ease muscle spasms and fight inflammation.

The team from London's Imperial College tested the urine of 14 healthy camomile tea drinkers.
Their research will appear in the Journal of Agricultural and Food Chemistry.

Olive oil acid 'cuts cancer risk'

Scientists in Chicago say they have uncovered why a Mediterranean diet rich in olive oil seems to cut the risk of developing breast cancer.

The key is an ingredient of olive oil called oleic acid, they say.

Northwestern University laboratory tests on breast cancer cells showed the acid sharply cut levels of a gene thought to trigger the disease.

Cancer charities said the study, in Annals of Oncology, was interesting, but more research was needed.

Folic acid 'cuts blood pressure'

Folic acid may help keep blood pressure in check, US researchers believe.

The study, in this week's Journal of the American Medical Association, adds to growing evidence of folate's cardiovascular benefits.

The Harvard team looked at data on about 156,000 nurses and found those with the lowest intakes of folate were at greater risk of hypertension.

Last week, researchers said folic acid - found in green leafy vegetables - might benefit people at risk of stroke.

Organic milk 'higher in vitamins'

Drinking organic milk has more health benefits than drinking non-organic, a study has suggested.

The research was presented to the Soil Association's annual conference in Newcastle.
It showed organic milk has higher levels of vitamin E, omega 3 essential fatty acids and antioxidants, which help beat infections.

But nutritionists said people who drank non-organic milk would be getting these nutrients from other sources.

Recognising a stroke

I was sent this in my e-mail and felt it was important to share. I have rewritten it a bit to make it more universal. I'll try to keep it at top position as long as possible.

Valuable information for everyone to keep in their memory bank.

A neurologist says that if he can get to a stroke victim within 3 hours he can totally reverse the effects of a stroke...totally. He said the trick was getting a stroke recognized, diagnosed and getting to the patient within 3 hours which is tough.

RECOGNISING A STROKE - A true story

Susie is recouperating at an incredible pace for someone who has had a massive stroke all because Sherry saw Susie stumble - - that is the key that isn't mentioned below - and then she asked Susie 3 questions. So simple - but this literally saved Susie's life - - Some angel sent it to Suzie's friend and she did just what it said to do. Suzie failed all three points and her friend called the emergency services.

Even though she had normal blood pressure readings and did not appear to be a stroke victim as she could converse to some extent with the Paramedics they took her to the hospital right away. Thank goodness for her friend's good sense.

Read and Learn!

Sometimes symptoms of a stroke are difficult to identify.

Unfortunately, the lack of awareness spells disaster. The stroke victim may suffer brain damage when people nearby fail to recognize the symptoms of a stroke.

Now doctors say a bystander can recognize a stroke by asking three simple questions:

1. Ask the individual to SMILE.
2. Ask him or her to RAISE BOTH ARMS.
3. Ask the person to SPEAK A SIMPLE SENTENCE (Coherently) (ie . It is sunny out today).

If he or she has trouble with any of these tasks, call the emergency services immediately and describe the symptoms to the dispatcher.

After discovering that a group of non-medical volunteers could identify facial weakness, arm weakness and speech problems, researchers urged thegeneral public to learn the three questions.
They presented their conclusions at the American Stroke Association's annual meeting last February.

Widespread use of this test could result in prompt diagnosis and treatment of the stroke and help prevent brain damage.

A cardiologist says if everyone who reads this tells another 10 people, you can bet that at least one life will be saved.
