Recently, there has been a resurgence of interest in botanical medicine and other complementary therapies. This blog will keep you in touch with the latest news.
Alcohol's health benefits doubted
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'
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'
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'
Onions, garlic, beans, carrots, corn, dark leafy vegetables and citrus fruits were among the most protective foods, according to the study.
A University of California team compared the diets of 2,200 people.
Cancer experts said previous studies had revealed similar findings, but more research was still needed.

Fibre cancer benefits questioned
Scientists remain divided over whether eating a high-fibre diet can reduce the risk of developing bowel cancer.
An analysis of data from 13 studies published in the Journal of the American Medical Association (JAMA) found there was no added protection.
But UK experts said other research found a high-fibre diet was of benefit.
In addition, they say there is no evidence a high-fibre diet causes harm, and that it has been shown to reduce the risk of heart disease and diabetes.

Vitamin D 'key for healthy lungs'
Patients with higher vitamin D levels in their blood had significantly better lung function, a University of Auckland team found in a study of 14,091 people.
The difference between the two was more marked than that between smokers and those who had quit, the study published in the journal Chest said.
Dietary supplements could boost lung function, the team suggested, but they added that more research was needed.

Chocolate may cut heart disease
They found eating a few squares a day may stave off artery narrowing and hardening in smokers by countering the disruption caused by their habit.
Smoking compromises the activity of both endothelial cells, which line the artery walls, and platelets, which are involved in blood clot formation.
The research, by University Hospital, Zurich, is published in Heart.
Olive oil's heart effect located
Mediterranean diets have long been hailed as cutting heart attack risk.
A team of Spanish researchers believes this is partly down to compounds called phenols that have anti-inflammatory, antioxidant and clot-preventing powers.
Virgin or extra virgin olive oils are best because they have the highest phenol content, the Journal of the American College of Cardiology reports.

Cranberries 'block tooth decay'
Scientists have found a compound in the fruit can stop bacteria from clinging to the teeth, blocking the formation of damaging plaque deposits.
However, researcher Dr Hyuan Koo warned many cranberry-containing products were loaded with sugar and consuming large amounts could lead to tooth decay.
The study, by the University of Rochester Medical Center in New York, will be published in Caries Research.
Chinese medicine outlets probed
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.

Plant oil 'acts like cancer drug'
It is down to a substance in the oil called gamma-linolenic acid that acts on the same receptor in tumours as the powerful breast cancer drug Herceptin.
Unlike Herceptin, which blocks the Her-2/neu receptor, GLA interferes with the gene carrying the DNA code needed to make the receptor work.
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?
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
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.

Cranberries can fight 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
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.
Ernst, however, added in the same vein, "This type of study can only be the first step in a line of research and at the end of this line, it's necessary to have good clinical proof that this works."

Egyptians ate lettuce to boost sex drive
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.

Cancer hope for green tea extract
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
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."

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.
