7 Natural Remedies for Fresh Breath

Fresh herbs
It’s widely known that mint can freshen breath, but chewing on fresh parsley can too. Parsley contains chlorophyll, which has anti-bacterial properties and a strong scent, which can freshen your breath in minutes. Other scented sprigs include coriander, tarragon, eucalyptus, cardamom, and rosemary.

Citrus snack

You may want to consider a clementine for an afternoon snack. Citrus fruits such as lemons, oranges, and grapefruits are packed with vitamin C, which helps prevent gum disease and gingivitis – major bad breath triggers

Homemade cinnamon mouthwash
Try making your own tasty mouthwash using common household ingredients. Just mix 1 ½ tsp of honey, ½ Tbsp ground cinnamon, 1/2 tsp baking soda, one cup hot water, and juice from two lemons. Swish about two Tbsp of this mouthwash for about a minute. The honey, baking soda, and cinnamon combat odor-causing bacteria, while the lemon provides a fresh scent. And there’s a bonus: baking soda whitens teeth.

Live active cultures
The live active cultures in yogurt and cheese have been shown to reduce odor-causing sulfites in the mouth, as well as unhealthy bacteria. Look for low-fat products without added sugars that contain Vitamin D, which helps create a most hostile environment for bacterial growth.

Black tea
Black tea contains polyphenols, antioxidants that prevent plaque from sticking to your teeth, and also inhibit the growth of odor-causing bacteria in the mouth. That’s why black tea can be so helpful in the battle against halitosis. Some popular types of black tea include Earl Grey, Ceylon, and Darjeeling.

Chewy concoction
Many exotic spices have antiseptic and antibacterial properties, making them ideal for keeping the mouth fresh and clean. Try crunching on a blend of fennel, coriander, and whole cloves. It tastes like a delicious winter treat.

Magnolia bark extract
This natural ingredient often found in mints and toothpaste is comprised of magnolol and honokiol, which have potent antibacterial properties. The powerful extract can kill most bad-breath bacteria within 30 minutes.

HIV drug used to reverse effects of virus that causes cervical cancer

A commonly-used HIV drug has been shown to kill-off the human papilloma virus (HPV) that leads to cervical cancer in a clinical trial led by The University of Manchester with Kenyatta National Hospital (KNH) in Nairobi.

Drs Ian and Lynne Hampson, from the University’s Institute of Cancer Sciences and Dr Innocent Orora Maranga, consultant in obstetrics and gynaecology at KNH in Nairobi examined Kenyan women diagnosed with HPV positive early stage cervical cancer who were treated with the antiviral HIV drug lopinavir in Kenya.

The study looked at 40 women with both high and low-grade pre-cancerous disease of the cervix and the antiviral drug, normally used orally to treat HIV, was self-applied directly to the cervix as a pessary.

The results, due to be presented at two international scientific conferences later this month and next, showed a high proportion of women diagnosed with HPV positive high-grade disease returned to normal following a short course of the new treatment.

The findings build on previous peer-reviewed laboratory based research carried out by Drs Hampson and will be submitted to a journal soon. They have been described by an independent leading specialist in gynaecological cancer as very impressive.

The 40 women, who were all HPV positive with either high-grade, borderline or low-grade disease, were treated with one capsule of the antiviral drug twice a day for 2 weeks. Repeat cervical smears showed a marked improvement within one month of the treatment although after three months, there was a definite response. Out of 23 women initially diagnosed with high-grade disease, 19 (82.6%) had returned to normal and two now had low-grade disease giving an overall positive response in 91.2 per cent of those treated. Furthermore the 17 women initially diagnosed with borderline or low-grade disease also showed similar improvement.

Photographic images of the cervix before and after treatment showed clear regression of the cervical lesions and no adverse reactions were reported.

Dr Ian Hampson said: “For an early stage clinical trial the results have exceeded our expectations. We have seen women with high-grade disease revert to a normal healthy cervix within a comparatively short period of time.

“We are convinced that further optimisation of the dose and treatment period will improve the efficacy still further.

“It is our hope that this treatment has the potential to revolutionise the management of this disease most particularly in developing nations such as Kenya.”

Cervical cancer is caused by infection with human papilloma virus (HPV) and is more than five times more prevalent in East Africa than the UK. In many developing countries, HPV-related cervical cancer is still one of the most common women’s cancers accounting for approximately 290,000 deaths per year worldwide. The same virus also causes a significant proportion of cancers of the mouth and throat in both men and women and this disease is showing a large increase in developed countries, such as the UK, where it is now more than twice as common as cervical cancer.

Dr Lynne Hampson said: “Current HPV Vaccines are prophylactics aimed at preventing the disease rather than curing or treating symptoms. Other than surgery, as yet there is no effective treatment for either HPV infection or the pre-cancerous lesion it causes which is why these results are so exciting.

“Further work is needed but it looks as though this might be a potential treatment to stop early stage cervical cancer caused by HPV.”

On a global scale HPV is the most common sexually transmitted disease. Although in the developed world vaccination programmes against HPV are well underway, these are not effective in women already infected with the virus. The current vaccines do not protect against all types of HPV and they are expensive, which can limit their use in countries with low resources.

The researchers believe their findings offer a potential cheap and preferably self-administered treatment that could eliminate early-stage HPV infections before these have developed into cancers would therefore have distinct health advantages. Approximately 300,000 women are dying from cervical cancer per annum which is equivalent to 800 per day, one every two minutes mostly in low resource settings.

The research has been backed by Lord Saatchi, whose wife novelist Josephine Hart died of ovarian cancer and has submitted a Private Member’s Medical Innovation Bill to Parliament which he argues would promote “responsible” innovation for medics to try new treatments without the fear of negligence claims. The bill comes amid claims there is currently an estimated average time lag of 17 years for a new treatment or research evidence to reach clinical practice in the UK.

Lord Saatchi said: “What Drs Lynne and Ian Hampson have done is amazing – a classic case of innovation. The fact that they needed to run their trial in Nairobi and that even now there is no guarantee the treatment will be available in the UK any time soon, is a source of immense frustration.”

Dr Ian Hampson added: “This is not something we could have done in the UK due to the associated costs and red tape. We have full ethical approval in Kenya and chose to conduct the trial there because of the extreme need for a self-applied treatment for early stage cervical cancer.

“During the trial we provided 820 women with free cervical smear testing in addition to a range of other free medical tests that are not routinely available in Kenya. This was essential in order to identify women with HPV related cervical disease so that we could treat them with lopinavir. It is very significant that during this process we also identified five women who already had invasive cervical cancer and these were immediately referred for surgery.”

Dr Pierre Martin-Hirsh, consultant in gynaecological and oncologist and associate editor in chief, the British Journal of Obstetrics and Gynaecological, has described the research as very impressive.

Scientists query health risk of food package chemicals

Scientists say “far too little” is known about the health risks of chemicals used in food packaging, and some could cause cancer.

Research is needed to understand the effect on the human body and embryonic development of at least 4,000 chemicals used in packaging, they said.

Links between packaging and obesity, diabetes and neurological diseases need to be explored, scientists warned.

But critics have said that the call is alarmist.

Scientists Jane Muncke, John Peterson Myers, Martin Scheringer and Miquel Porta called for an investigation into the health risks of food packaging in a commentary piece published in the Journal of Epidemiology and Community Health.

‘Lifelong exposure’
They noted that chemicals such as formaldehyde, which they said can cause cancer, were used in many materials, such as plastics used for fizzy-drink bottles and tableware.

Substances could leach into food, and they added that the risks of “lifelong exposure” to such chemicals were not documented, said the researchers.

“Whereas the science for some of these substances is being debated and policymakers struggle to satisfy the needs of stakeholders, consumers remain exposed to these chemicals daily, mostly unknowingly,” they said.

But carrying out analysis would not be easy, they said, as there are no unexposed populations for comparison.

The call for research has attracted criticism.

Dr Ian Musgrave, senior lecturer in pharmacology at the University of Adelaide, said it was “very hard to take seriously” the claims that formaldehyde in plastic bottles could cause cancer.

He said it was present in many foods naturally, and to consume as much formaldehyde as that in an apple someone would have to drink “at least” 20 litres of plastic-bottled water.

Dr Musgrave added: “Obviously the concern about formaldehyde from food packaging is significantly overrated, unless we are willing to place ‘potential cancer hazard’ stickers on fresh fruit and vegetables.”

‘High levels of fat’
Jon Ayres, Professor of Environmental and Respiratory Medicine at the University of Birmingham, said the scientists painted an “alarmist” picture.

He said there was “no denying” that ingesting lower doses of some substances could “in principle” be harmful, but the issue was how to recognise and quantify any effect.

Prof Ayres added: “But can these effects really be anything other than modest at worst when few have been recognised to date?”

He said that simply calling for a different approach to the chemicals “does not really help”.

Dr Oliver Jones, lecturer at the RMIT University in Melbourne, Australia, said: “More research is always welcome from a scientist’s point of view.

“But I would hazard a guess that the high levels of fat, sugar and salt in a lot of today’s processed food are more of a health concern than any migration of chemicals from the packaging.”

Why You Should Eat With Your Hands?

1) It’s primal

Eating with your hands is common in many parts of the world.Utensils are a man-made invention that not all cultures warmed up to. We’ve learned so much from our ancestors and various hunter-gatherer tribes about health and nutrition – could they be onto something here, too?

2) Improved digestion

Feeling your food is a like a heads-up to your stomach, signaling “Incoming!” Your hands become an extension of the digestive system. Millions of nerve endings in your fingers relay the message that you’re about to eat, including the temperature of the food, level of spiciness, etc. to prep the stomach for digestion. Handling the food with your fingers releases digestive juices and enzymes.

3) Heightened awareness

Many experts have noted the importance of being relaxed and “present” at mealtime. A calm, aware state allows optimum digestion and helps with not overeating. Eating with a fork and knife can become mechanical, done absentmindedly while watching TV. You’ll inevitably feel more connected with your food when you eat with your hands.

4) Engages all senses

The smell of your cooking fills your home. The feast looks appetizing. You hear how crunchy it is as you take that first bite. And of course it tastes delicious. But as far as feeling it, you’re limited to the textures you experience in your mouth. Or are you? Eating with your hands adds a tactile dimension to your meal and engages all of your senses. Some people firmly believe that to completely enjoy your food, you simply must eat it with your fingers.

5) It’s fun

Don’t kids just look so happy and carefree, eating with their hands? Live a little, try something new, have some fun 🙂

Soon, ‘vision-restoring drug’ that will let blind eyes see light

Researchers have developed a compound that can be effectively used for treating patients suffering from degenerative retinal disorders such as retinitis pigmentosa and age-related macular degeneration.

The retina has three layers of nerve cells, but only the outer layer contains the rod and cone cells that respond to light, enabling us to see the world. When the rods and cones die during the course of degenerative blinding diseases, the rest of the retina remains intact but unable to respond to light.

Dr. Richard Kramer of the University of California, Berkeley and his colleagues have invented “photoswitch” chemicals that confer light sensitivity on these normally light-insensitive ganglion cells, restoring light perception in blind mice.

An earlier photoswitch required very bright ultraviolet light, making it unsuitable for medical use. However, a new chemical, named DENAQ, responds to ordinary daylight. Just one injection of DENAQ into the eye confers light sensitivity for several days.

Experiments on mice with functional, nonfunctional, or degenerated rods and cones showed that DENAQ only impacts ganglion cells if the rods and cones have already died.

It appears that degeneration in the outer retina leads to changes in the electrophysiology in the inner retina that enables DENAQ photosensitization, while the presence of intact photoreceptors prevents DENAQ action.

The selective action of DENAQ on diseased tissue may reduce side effects on healthy retina, exactly what is desired from a vision-restoring drug.

The study was published in the Cell Press journal Neuron.

5 reasons why walking on grass is good for your health

There is a common belief that walking on grass in the morning and evening is a great for your health; especially for your eyes. Have you ever wondered why? Well, here are five reasons waking on grass can do a great deal of good for your mind and body.

Rejuvenates your senses and calms the mind: The entire environment in the morning – the fresh air, sunlight and peaceful atmosphere helps you in innumerable ways. Fresh oxygen helps your body work better, sunlight helps you keep warm, replenishes your vitamin D stores and the calm atmosphere helps relax your entire body and mind, allowing you to let go of all your stress. Apart from that the green colour of grass, helps stimulate your body to produce calming hormones that help you relax

Stimulates your entire body, including the eyes: Our feet are store houses of reflexology zones that correspond to various organs of our body. According to the principles of reflexology, stimulating these points can help relieve ailments of the particular organs and keep them in a general state of good health. The foot has points for the eyes, ears, lungs, nerves of the face, stomach, spleen, brain, kidneys and many more organs, so when we walk on grass, these areas are gently stimulated, helping your entire body stay healthy. Dr Anjali Sharma, senior consultant, Naturopathy, Sri Balaji action medical institute, Delhi says, ‘When we walk on grass we stimulate the nerve endings of the foot, where thousands of nerve endings converge. These nerve endings get gently yet directly stimulated by the grass, helping the body stay in a state of equilibrium.’

Another reason for this belief is that when we walk, we put maximum pressure on the first, second and third toe. The reflexology pressure points for the eyes are present on the second and third toes, which is why walking on grass has a large number of benefits for one’s eyes.

Connects you to the earth and neutralizes your electrical energies: Dr Anjali says, ‘In naturopathy we base our treatment on the five elements of nature, out of which one of the elements is earth. The earth contains magnetic fields and has a certain flow of energy. Therefore when we walk barefoot on grass, we directly get connected to the magnetic field of the earth, which affects the entire electrical and magnetic field of our body. This exchange of energies helps neutralize negative electrical impulses in our body which are known to cause certain ailments. Therefore, cleansing our bodies of negative electrical energies definitely has a positive effect on our overall health.’

Lets you soak in the sun: When we walk on grass early in the morning we give our bodies the precious gift of ‘sun energy’. Dr Anjali says that sun energy is a great source of healing energies and restorative powers. ‘Sun energy’ – as it is called in Naturopathy – is the source of life and energy. It helps disinfect the body, tones the muscles and nerves, supplies the entire body with energy and supplies the body with the all essential vitamin D.

Dr Anjali suggests that, ‘Walking in the sun is extremely important and beneficial and one gets the maximum benefit of the sun between 6:30 to 9 in the morning and between 4:30 or 5 to about 6:30 in the evening. That being said, one should be careful not to expose themselves to harsh sunlight that we commonly see in the afternoons, as this can be damaging to the body.’

Replenishes your vitamin D stores: In recent times, osteoarthritis and other bone related diseases have become common place. Doctors say that this is mainly due to the lack of exposure to the sun. Therefore when you walk in the open – early in the morning – the sun replenishes your vitamin D stores automatically, helping you keep bone and joint diseases at bay. If you are pregnant, this vitamin is all the more important for you

Sitting linked to increased risk for disability, study shows

Here’s another reason desk jockeys need to get up and move. Researchers are finding that sedentary behaviors like sitting even just an hour extra per day can up your risk for disabilities in later life — even if you are a moderately active gym rat.

The study published Wednesday in the Journal of Physical Activity and Health is the first to show that sedentary behavior alone may be an independent risk factor for disability, separate from lack of moderate physical activity, its authors say.

To be clear, exercise is important, but it is only the beginning of a healthy lifestyle, said lead author Dorothy Dunlop, Ph.D., professor of medicine at Northwestern University Feinberg School of Medicine in Chicago.

“The message is that we can work on what the government recommends in terms of moderate physical activity, but we need to reduce sitting time by replacing it with some light activity,” Dunlop said. That doesn’t mean sweat and spandex, but rather simple activities like pushing a grocery cart, strolling through a museum, and even getting up once an hour to walk around.

The researchers strapped devices to the waists of some 2,200 adults aged 60 and older to monitor their activity and found that every additional hour a day spent sitting was strongly linked to a doubling of the risk of disability. So, if one 60-something year old person is sedentary for 12 hours a day, and another is sedentary for 13 hours a day, the second individual is 50 percent more likely to be disabled, according to the study.

“I’m not surprised that 30 minutes of activity several times a week doesn’t compensate for nine hours a day sitting around,” said family medicine specialist Dr. Robert Truax of University Hospitals Case Medical Center in Cleveland. The good news, he said, is that it’s never too late to get up off our butts and get healthier.

FDA approves Chelsea Therapeutics drug for low blood pressure

Chelsea Therapeutics International Ltd’s drug Northera, which treats a rare form of low blood pressure associated with neurological disorders such as Parkinson’s disease, has won U.S. approval, the Food and Drug Administration said on Tuesday.

The company’s shares rose 34 percent to $6.63 in after-market trading.

The drug’s label will carry a boxed warning, the most serious possible, of the risk of supine hypertension, or increased blood pressure while lying down, a danger that can cause stroke.

In January, an advisory panel to the FDA recommended approval but also suggested the company conduct a follow-up study to prove durable benefit. Panelists said gaps in clinical data made it hard to determine whether Northera, which appears effective after a week’s treatment, is effective over the long term.

The FDA followed the recommendation and approved the drug on an “accelerated” basis. This allows for approval a drug to treat a serious disease based on an intermediate measure while the company conducts more trials.

In the meantime, the FDA said, “it is essential that patients be reminded that they must sleep with their head and upper body elevated. Supine blood pressure should be monitored prior to and during treatment and more frequently when increasing doses.”

Chelsea first filed for approval of Northera in 2011. The FDA rejected the drug in 2012 and asked for additional data. The company is also testing the drug, known generically as droxidopa, in mid-stage studies to treat fibromyalgia and intradialytic hypotension.

Fecal Transplant Regulations Are Too Strict, Researchers Say

c-difficile

Physicians use fecal transplants to treat certain intestinal infections, but the procedures recently came under strict regulations, with the Food and Drug Administration managing the transplants as though they were a drug treatment.

This regulation has made it harder for patients to receive fecal transplants, and in a new paper, some researchers are calling for the transplants to instead be regulated as a tissue, akin to blood donations.

The raw material for fecal transplants isn’t hard to come by, and so in the face of what some see as current over-regulation, an underground market for the transplants will likely spring up, the researchers argued today in the journal Nature.

At the same time, they said, more research is needed on the long-term effects of fecal transplants.

Regulating fecal transplants as a tissue may allow for better research on their possible uses in treatments, while protecting patients from harm, the researchers, from MIT and Brown University, wrote.

“I think regulating it as a tissue product would both provide access as needed and the research that could bring some pretty exciting new treatments on the scene,” said Mark B. Smith, an author of the article and a doctoral candidate at MIT.

Fecal transplants have been tested since the 1950s, and last year the first randomized controlled trial showed a strong benefit in helping patients with recurrent C. difficile, a bacterial infection that causes painful diarrhea, often following the use of antibiotics, and kills 14,000 people yearly in the United States.

But following the treatment’s success, some doctors began offering fecal transplants for other conditions as well — including those for which any potential benefit remains unproven. The FDA took action in 2013, regulating the treatment, but also granting an exemption for its continued use in patients who had C. difficile infections. This use would not require special permissions.

However, the result may be a case of both under- and over-regulation, today’s editorial argues. While medical societies have issued guidelines for using the treatment, there are no hard and fast rules for screening fecal matter, as there are with blood donations.

Can Pizza Prevent Norovirus?

You may have heard of binging on pizza as a cause of stomach distress, but how about a a cure?

Researchers found that a chemical in oregano called carvacrol causes norovirus to break down in mice, according to a study published today in the Journal of Applied Microbiology.

“Carvacrol could potentially be used as a food sanitizer and possibly as a surface sanitizer, particularly in conjunction with other antimicrobials,” Dr. Kelly Bright, who led the research at the University of Arizona said in a press release. “We have some work to do to assess its potential but carvacrol has a unique way of attacking the virus, which makes it an interesting prospect.”

Carvacrol, which gives oregano its distinctive flavor, caused the layer of proteins surrounding the vomit-inducing virus to break down. Another antimicrobial would then be able to get into the virus and kill it.

Since carvacrol doesn’t produce any noxious fumes or by-products, it has good potential to be used in sanitizers for schools or hospitals, the researchers noted.

Oregano has developed a reputation as a super-spice. In 2012, researchers from Long Island University discovered that it may also be used to treat prostate cancer. In that study, researchers found that carvacrol could be used to induce “cell suicide.”

“Some researchers have previously shown that eating pizza may cut down cancer risk,” Dr. Supriya Bavadekar, assistant professor of pharmacology at Long Island University said in a press release. “This effect has been mostly attributed to lycopene, a substance found in tomato sauce, but we now feel that even the oregano seasoning may play a role.”
