The powers of Curcumin by Natural Society

Curcumin by "Natural Society"


Curcumin comes from the Turmeric plant and has been in India as a spice for centuries.

Traditionally, people used curcumin to add flavour to their dishes, with many cultures recognizing the spice for its many medicinal properties.

As the use of curcumin continues to grow in popularity, so does the acknowledgement of its many benefits.


The world of modern medicine has discovered that curcumin is effective in the treatment of diseases and in the prevention of cancer.

In one study, it was found that curcumin reduced brain tumor size by 81%. Another study found just 1,000 milligrams of curcumin can help stop the growth of cancer.

However the benefits of curcumin do not end there.


Amazingly, curcumin has been found to benefit over 560 negative conditions including: Alzheimer’s disease, oxidative stress, DNA damage, inflammation, HIV infections, and cancer.

Studies performed on lab mice showed that curcumin also effectively treated kidney problems and restored kidney functions.


The rise in Alzheimer’s disease cases has opened the eyes of the modern world to the gravity of this disease, with curcumin showing extreme promise in the treatment and prevention of Alzheimer’s.

Studies have shown that curcumin can be instrumental in the treatment of this disease.


Curcumin is even effective in lowering bad cholesterol levels naturally. Curcumin is effective in lowering LDL (bad cholesterol) and increasing HDL, or good cholesterol. When taken on a daily basis, curcumin may significantly decrease LDL levels.


Preliminary findings on studies in the use of curcumin in the treatment of Human Immunodeficiency Virus (HIV) have shown that the virus does react to curcumin treatment.

As more health professionals become aware of this information, we could possibly see curcumin being formally used in the treatment of HIV in the future.


Curcumin is also used in the treatment of arthritis and cataracts.


As studies on the health benefits of curcumin are being performed routinely, more and more health benefits are expected to be seen in the future.

Three Health Benefits an Athlete Can Gain from Acupuncture

Three Health Benefits an Athlete Can Gain from Acupuncture

Here are three of the best health benefits that an athlete can gain from acupuncture therapy, which can improve his or her performance on the field.

Can Relieve Muscle or Joint Pain

If an athlete is suffering from muscle or joint pain, he or she might decide to try acupuncture, since it can relieve these symptoms. Acupuncture has long been used to treat all sorts of pain, which can include pain coming from the muscles and joints. An athlete might have muscle or joint pain as the result of an injury, which can hinder his or her athletic ability. Acupuncture can help reduce the inflammation associated with the injury, and it can help treat the source of the pain or inflammation. If an athlete regularly participates in sports, then acupuncture therapy might help prevent pain or inflammation from starting in the first place. Acupuncture can help with spasms in the muscles, contusions under the skin, arthritis, osteoporosis, and a variety of different conditions that cause muscle or joint pain.

Can Ease Stress or Anxiety

An athlete that is suffering a lot from stress or anxiety should try acupuncture therapy, because acupuncture can basically eliminate stress or anxiety. Acupuncture helps unblock various energy channels within the body, which can eliminate stress or anxiety. An athlete is likely to become stressed or anxious at some point during his or her sport, especially right before an upcoming game. If an athlete is under too much stress, then he or she will likely perform poorly during the competition, and he or she is also more prone to injuries. An athlete that is always anxious is also more likely to suffer injury, since anxiety can hinder his or her concentration. Acupuncture is a great way to help an athlete overcome anxiety or stress related to his or her sport, and can help improve his or her overall mentality. Stress or anxiety can also cause an athlete to become depressed or feel worthless, so it is important that he or she treat these symptoms promptly.

Can Improve Circulation and Promote Healing

Acupuncture can also improve circulation, which can help speed up the healing process, and this is a huge benefit for an athlete. If an athlete has suffered an injury, which is bound to occur sooner or later, he or she will want to recover as fast as possible. Poor circulation throughout the body can hinder healing, because oxygenated blood is what helps repair damaged cells. If an athlete is trying to recover from an injury, then he or she will likely want to do everything possible to increase the circulation throughout the body. Acupuncture can help move blood throughout the body, which means that oxygenated blood is getting to vital organs to help promote healing. Since acupuncture can help reduce pain or inflammation, an athlete will heal faster because he or she will not suffer from muscle spasms as often. Acupuncture can help release and regulate hormones, which are important for healing, and endorphins will naturally be released within the body to also promote healing.

Why Ice may be bad for sore Muscles

Why Ice May Be Bad for Sore Muscles
By GRETCHEN REYNOLDS
Should you ice a sore back? Is ice the best remedy for an aching muscle?


Already, the benches in gym locker rooms and beside basketball courts are filling with 2012’s early casualties, those of us who, goaded by New Year’s resolutions, are exercising a bit too enthusiastically and developing sore muscles. Many of us will then drape ice packs over our aching muscles. But a new review article published this month in the journal Sports Medicine suggests that for sore muscles, ice is not always the panacea that most of us believe it to be and that, in some instances, it can be counterproductive.

For the study, researchers at the University of Ulster and University of Limerick in Ireland reviewed almost three dozen earlier studies of the effects of using ice to combat sore muscles, a practice that many who exercise often employ. Ice is, after all, the “I” in the acronym RICE (rest, ice, compression, elevation), which remains the standard first-aid protocol for dealing with a sports-related injury. Icing is also widely used to deal with muscles that twinge but aren’t formally injured. Watch almost any football, basketball or soccer game, at any level, and you’ll likely see many of the players icing body parts during halftime, preparing to return to play.

But there has been surprisingly little science to support the practice. A 2004 review of icing-related studies published to that point concluded that while cold packs did seem to reduce pain in injured tissues, icing’s overall effects on sore muscles had “not been fully elucidated” and far more study was needed.
Related

Last year, a small-scale randomized trial found no discernible benefits from icing leg muscle tears. The cooled muscles did not heal faster or feel less painful than the untreated tissues. But, as the researchers point out, it is difficult to scientifically study icing, since you can’t blind people to whether they are receiving the therapy or a placebo. People generally can tell if their muscles are getting cold or not.

Which leaves the findings of the new review about icing by athletes as the best overview we may have for now. And the findings are not altogether comforting.

The authors write that, in a majority of the studies they looked at, icing was quite effective at numbing soreness. But it also significantly reduced muscle strength and power for up to 15 minutes after the icing had ended. It also tended to lessen fine motor coordination. Some of the reviewed studies found that people experienced impaired limb proprioception, or their sense of where their limb was in space after it had been iced.

The result was frequently, at least in the short term, poorer athletic performance. Volunteers were not able to jump as high, sprint as fast, or throw or strike a ball as well after 20 minutes of icing.

“The current evidence base suggests that the performance of athletes will probably be adversely affected should they return to activity immediately after cooling,” the authors conclude.

Why an ice pack before exercise should depress performance isn’t fully understood, though there are several theories. “The most likely reason is that ice reduces nerve conduction velocity,” said Chris M. Bleakley, a research associate at the University of Ulster who led the study. “Nerve impulses in the muscle slow down.” Cooling, he said, also probably “affects the mechanical properties of the muscle tendon unit,” meaning that the muscles and tendons, which should work together seamlessly, do not.

There’s also the possibility that icing sore muscles may increase the risk of injury, though the studies did not examine this issue directly. If your iced shoulder or legs feel sluggish during a tennis match or run, the authors suggest, you presumably will push harder, even as the iced muscle, being numb, doesn’t alert you to the beginnings of a more severe injury. The risk really applies “to situations where athletes are returning to competition immediately after icing,” like when you apply a cold pack before a run or “ice on the sidelines or at halftime to treat pain and discomfort,” Dr. Bleakley said. That means for most of us, there may be times when it’s fine to ice sore muscles – like after a hard workout or when we experience serious injury — provided we do not jump back into the field.

Most earlier studies have found little benefit from icing after exercise, but also few negative side effects. And if we must resume activity, the negative effects of icing are thankfully short-lived, usually disappearing within about 15 minutes. They also were less severe if the icing time was shortened, Dr. Bleakley says. “Application times of three to five minutes had much less of an adverse effect on performance” than keeping the ice pack in place for 20 minutes or more, he said.

The fundamental lesson of the review is clear.

“Ice has many benefits,” Dr. Bleakley says. “It is cheap and remains an excellent method of numbing pain.”

But relying on ice to get you back into that senior-league basketball game or onto the running track when you’re already sore is inadvisable. “Athletes should consider that pain is usually a sign that something is wrong with your body,” Dr. Bleakley says. Listen, and stay out of the second half of the senior-league basketball game or skip a day’s run. You have the rest of 2012 to fulfill your resolution.

Article - Easing Menopause symptoms with Food


Easing Menopause Symptoms With Food

Posted: 06/28/11 09:51 AM ET


"I didn't sign up for this, I just want to feel normal again," said Judy, my patient who aptly describes what the 21st century Western woman going through menopause feels. If you want to know how to turn down your body's internal "thermostat" you are in the right place. Alternative medicine, including food therapy, is a viable option for managing menopause symptoms.

Menopause symptoms such as hot flashes, night sweats, irritability, brain fog and other symptoms seem to be considered the norm for women over the age of 50. Researchers from the Department of Integrated Health at Westminster University polled 1,000 British women ages 45 to 55 and compared their answers to those of women from the U.S., Canada, Japan and China. The conclusion was that Japanese and Chinese women suffer the least amount of menopause symptoms. British women suffer the most and Americans are somewhere in between.1 For any woman sweating through this life change, you can stop the roller coaster and "get back to normal" using alternative medicine.

What causes this disparity between menopausal women in the East and West? In Japan, Malaysia, Hong Kong, Taiwan and China women do not generally seek medical attention for menopause symptoms.9 The reasons for these cultural differences are complex. Certainly diet and lifestyle choices play a key role. The question is why don't women in these cultures need Hormone Replacement Therapies (HRT) or medical treatments the way that the majority of Western women do?

The last year has been a confusing time with medical flip-flops on the benefits and dangers of artificial hormones. I see more and more women who are giving up on trusting research produced by the health care establishment and looking to alternative medicine for answers.

Not only is it difficult to stay keep up with the latest menopause drug treatment information, but much too often this advice is influenced by drug companies or doctors who fail to disclose their ties to study outcomes. One truth every doctor knows is that medicines have risks. Medicines should be prescribed only when the benefits outweighs the risks, including the risks of side effects which may not show up until years later. Healthy diet and lifestyle therapies have no risks. Cooking with Chinese herbs and incorporating food therapy have been done for centuries and have absolutely no known risks.

This article is part two on the subject of alternative medicine for menopause. Part one (see it here) explained how Traditional Chinese Medicine (TCM) views menopause. TCM recognizes menopause as part of the natural aging process and is often termed Kidney Yin Deficiency. The manifestations of aging include gray hair, dryness and the end of menstruation -- in other words, signs the kidney energy is waning.

TCM views the kidney energy as sustaining the metabolic process and decreases naturally as we age. When the balance of kidney yin and yang energy is "upset," symptoms such as hot flashes and night sweats may appear. Throughout Asia it is Chinese herbs and food that are most commonly used to gently tonify the kidney energy and restore the balance between yin and yang. Acupuncture is also used to restore this balance and studies have proven its effectiveness.10 The role of herbal medicine was discussed in part one and I now want to address the roll diet plays in menopause.

It seems Asian cultures understand Hippocrates, the father of medicine's credo, "Let food be thy medicine and medicine be thy food." Asian cultures blend four important principals into every meal.

1. Meals consist of varying food temperatures, i.e. peppers are a hot food, seaweed is cold and black beans are warm.

2. A large variety of foods with five flavors are eaten in every meal. The five flavors are sour, sweet, pungent, bitter and salty.

3. Soy products are eaten nearly every day.

4. An old Chinese Proverb says, "He that takes medicine and neglects diet, wastes the skill of the physician."

Food Temperatures
Since our goal here is to turn down the thermostat, let's start the discussion with "cold" foods -- or foods that cool us off. This is the same principle applied to eating watermelon on a hot summer day. Asian cultures use food temperatures to balance the body's needs.

Cold herbs and foods simply cool you off. But the principal is best practiced in combination. Mixing cold foods and warm foods is best. Too much cold food inhibits digestion and may lead to diarrhea. A few of the best cold foods are: cucumber, diakon radish, mung bean, dandelion greens, cabbage, bok choy, cauliflower, celery, carrots and romaine lettuce. Eat a least two servings of these a day for your internal air conditioner to kick into action. Cold fruits include lemon, cantaloupe, grapefruit, mulberry, apples, pears, watermelon, apricots and persimmons.

Five Flavors
Incorporating the five flavors into your meals may be a new concept but is not all that difficult. There are several good books on this subject. One of my favorites is The Tao of Nutrition by Ni and McNease. Bitter foods will help the most for those suffering with menopause symptoms. They operate as an internal air conditioner, because bitter foods disperse heat. Examples of bitter foods include kale, green tea, watercress, turnips, asparagus and tangerine peel. Tangerine peel is used in Chinese herbal medicine and in TCM food therapy. Adding tangerine peel to meat or vegetables helps by promoting the circulation of stomach Qi, (energy) thereby improving digestion. Its bitter and acrid flavor not only helps digestion but relieves indigestion. Tangerine peel strengthens the stomach and works like a carminative to clear excess mucus. (More herbs for menopause here.)

Soy Foods
One interesting cultural advantage for menopausal women in Asia may be the amount of soy or tofu eaten daily. Soy is full of protein, rich in vitamins and enzymes. It's an isoflavone, a class of phytoestrogen (plant derived compounds) with estrogenic activity.11 Soy has been part of the Asian diet for thousands of years. Unprocessed tofu is made fresh and sold in nearly every market. Soy tofu is eaten in small amounts daily from the time children are very young to the end of their lives.

But, the key here is the soy and tofu they eat is made from "unprocessed and non-gmo" soy beans. Sadly, this is increasingly difficult to find in American stores and nearly all American soy beans are derived from genetically modified organisms (GMO). Not a healthy choice to start with and unfortunately most of our tofu is manufactured through a highly refined process. For this reason, I would not consider soy tofu a healthy food in the U.S. right now.

Refined food products almost always lose their nutritional value after being heated to extreme temperatures. This process kills all of the nutrients and all of the important enzymes which the body needs to digest them. As a result, eating processed American soy tofu can give you terrible gas, bloating and indigestion and even worse, it's becoming a common allergen. A small serving of soy a couple of times a week won't harm you, but I recommend eating only fermented and non-GMO soy. Products such as miso, sprouted tofu, soy yogurt and tempeh are my first choice. A little organic soy sauce is also ok . If you can be certain your tofu is organic and unprocessed I would consider it a healthy choice.

Changing the way you look at food according to temperature and taste takes some time. Maybe this is a new concept for you and maybe you've never seen some of the foods listed above. Although you may not choose to eat everything on this list, you can certainly eat some.

Tapping into your body's internal thermostat doesn't work exactly like the thermostat on your wall. So, be patient. Be consistent with dietary changes and enjoy the food you eat. Find some recipes you like and bring variety to your diet every day. Incorporate the five flavors of salty, bitter, sour, pungent and sweet into your lifestyle. Chinese medicine uses food therapy full of phytochemicals, vitamins and nutrients to restore vibrant health and balance to the entire person. This therapy has been adopted for thousands of years without any side effects.

What part of your diet will you change to help your menopause symptoms?

Chinese medicine offers new Parkinson's treatments

There's an active ingredient in there somewhere (Image: Sipa Press/Rex Features)

There's an active ingredient in there somewhere (Image: Sipa Press/Rex Features)

A hooked herb, root extract and a dash of bark – it may sound like a witches' brew, but these compounds could provide treatments for diseases that have so far foiled western doctors, such as Parkinson's and irritable bowel syndrome.

For over 2000 years Chinese doctors have treated "the shakes" – now known as Parkinson's disease – with gou teng, a herb with hook-like branches.

Early this year, 115 people with Parkinson's were given a combination of traditional Chinese medical herbs, including gou teng, or a placebo for 13 weeks. At the end of the study, volunteers who had taken the herbs slept better and had more fluent speech than those taking the placebo.

Gou teng appears to stabilise symptoms, says Li Min, a traditional Chinese doctor at Hong Kong Baptist University. Now, Li and her colleagues have figured out how it might work.

Preserving dopamine

Parkinson's symptoms, such as muscle tremors, slowness of movement and rigidity, are caused by the progressive destruction of brain cells that produce dopamine. Previous work has suggested that an abundance of a protein called alpha-synuclein may be to blame. Current treatments aim to boost levels of dopamine, which only partly alleviates symptoms and does not affect the protein clusters.

It is thought that clumps of alpha-synuclein accumulate because brain cells cannot remove them through autophagy – a type of programmed cell death. Mice without the genes needed for autophagy quickly develop Parkinson's-like symptoms.

According to Li, autophagy is the only known process that gets rid of abnormal proteins within cells. "Enhancing this pathway may be key to treating Parkinson's," she says.

Li's team screened gou teng for its active compounds and tested which of these compounds increase the rate of autophagy and remove alpha-synuclein. To do this, the team added the compounds to human nerve cells and fruit flies that had been genetically modified to develop alpha-synuclein clusters.

Rapamycin connection

One of the compounds, an alkaloid called isorhy, induced autophagy for alpha-synuclein at a similar rate to a drug called rapamycin. Rapamycin is normally used to suppress the immune system in transplant patients, but has recently been touted as a promising candidate for Parkinson's treatment because it prevents nerve cell death in flies with a Parkinson's-like disease. However, because rapamycin depresses the immune system, it would have serious side effects for people with Parkinson's. Gou teng, meanwhile, has been taken for centuries with no apparent side effects.

Further testing found that isorhy activates autophagy through a different pathway to rapamycin, which may explain why it does not affect the immune system in the same way. Li, who recently presented her results at the Keystone Symposia on Molecular and Cellular Biology in Whistler, British Columbia, Canada, will begin trials of Isorhy in rodents later this year.

Herbs for the gut

Meanwhile, Zhaoxiang Bian, also at Hong Kong Baptist University, is developing a drug called JCM-16021 for irritable bowel syndrome (IBS) using seven herbal plants and based on a Chinese formulation called tong xie yao fang, used to treat IBS since the 1300s.

IBS affects up to 20 per cent of people, causing abdominal pain, constipation and diarrhoea. "They feel really rotten, and it's sufficiently severe for people to take time off work," says John Furness at the University of Melbourne, Australia. Stress management can help symptoms, but there is no effective medicine to treat it.

In 2007, Bian gave 80 people with IBS either JCM-16021 with Holopon – a drug that interrupts nerve impulses in the parasympathetic nervous system responsible for digestion – or Holopon alone. After eight weeks, 52 per cent of those given JCM-16021 with Holopon reported reduced IBS symptoms, compared with 32 per cent of those given Holopon alone.

IBS is partly caused by high levels of serotonin in the gut. Last year, Bian found that giving JCM-16021 to rats with IBS-like symptoms broke down serotonin in their bowel faster than normal, reducing their discomfort.

His team has since isolated several active compounds in JCM-16021 that block serotonin's activity in the rat gut, including magnolol, a herb taken from the bark of Magnoliae officinalis.

Root of relief

This month, Keiko Lee at Juntendo University in Tokyo, Japan, found that paeoniflorin, a root extract used in JCM-16021, acts as an analgesic in rats, inhibiting adrenaline receptors in the spine.

Bian is now combining the active extracts of JCM-16021 to develop a new drug that attacks IBS from different angles. Unlike conventional approaches, which target only one aspect of the disease, he believes the combination drug will be more effective.

"I think it is a very rational way to go," says Furness, but warns that combination drugs usually take longer to gain approval because of the greater-than-usual possibility of unexpected side effects. But because these compounds have a long history of being safe for human consumption, it is hoped they will be approved faster, says Li.

"In the past the pharmaceutical industry didn't put much effort into traditional Chinese medicine," says Jing Kang, a biochemist at Harvard Medical School in Boston. "In the past few years this has been changing. More people are paying attention."

Acupuncture Facial Rejuvenation

Acupuncture Facial Rejuvenation

Acupuncture has been used to treat skin complaints and reduce signs of aging for centuries. In fact, facial rejuvenation acupuncture, also known as cosmetic acupuncture, has a recorded history going as far back as China's Sung Dynasty (960AD - 1270AD), when the Empress and the Emperor's concubines used it to engender beauty and good health.

Facial rejuvenation acupuncture can improve muscle tone, increase collagen production, tighten pores and boost circulation and moisture in the skin. Moreover, when acupuncture is used to create overall balance within the body, the physical, mental and emotional patterns that contribute to aging are addressed, helping you look and feel younger.

The theory behind facial acupuncture is that hair-thin needles inserted along wrinkles and frown lines stimulate energy and relax the muscles. This leads to a tightening of the facial muscles, which decreases sagging of the facial skin, and an increase in the production of collagen, filling in fine lines and wrinkles.

Benefits of Acupuncture Facial Rejuvenation:
Increases the production of collagen and elastin
Improves muscle tone (preventing further aging and wrinkles)
Improves local lymph and blood circulation
Softens or erases fine lines and wrinkles
Reduces the depth of deeper lines
Decreases bags (puffiness) under the eyes
Reduces or eliminates acne and rosacea
Provides a consistently smoother and brighter face
To look and feel years younger, facial rejuvenation acupuncture offers less risk, expense and recovery time than medical alternatives. While this procedure cannot reshape facial features, it is a more subtle rejuvenation that can take years off one's face safely and naturally while improving overall health.
