Importance of Resveratrol

'Wine'-No other beverage has attracted the attention of modern medicine like this drink. Although it is most widely known for its benefits for the heart, it also helps fight against cancer, dementia, and other age-related diseases. Researchers in Denmark recently conducted a survey of 25,000 people to find out what drinking alcohol does to mortality and discovered that wine drinkers slash their overall risk of dying from any cause by about 40%.

Chemists took wine apart years ago to find out what makes it tick. Basically, it contains a host of plant compounds. Unfortunately, resveratrol and some of the other beneficial components got shelved as “toxicants,” and nobody paid much attention to them until a scientist tried to figure out why the French can eat so much fat and not get heart disease. It turns out that part of the answer to the “French paradox” is resveratrol which is present in red wine.

Resveratrol is naturally created by certain vines, pine trees, peanuts, grapes, and other plants. One of these plants (Polygonnum cuspidatum) is an ingredient in traditional Asian medicines that are prescribed for liver and heart conditions. It is classified as a polyphenol because of its chemical structure. Polyphenols make up a huge group of plant compounds that are further broken down into other classifications such as flavonoids, proanthocyanidins, and the like.

In the early ‘90s, after wine was pinpointed as the probable answer to the “French paradox,” researchers realized that the resveratrol content of wine might be the secret ingredient behind the healthy heart effects attributed to it. Research began in earnest, and just over a decade later, the accolades are enormous: “marked antioxidant activity,” “shows great promise for preventing cardiovascular disease,” “remarkable inhibitor,” “chemotherapeutic, little or no toxic effects in healthy cells,” “high efficacy against multiple sites.” Dozens of studies were published in this past year alone.

Resveratrol is a dietary agent that has powerful and diverse effects on the heart and blood vessels. It was also shown recently that resveratrol possesses a “novel mechanism” for scavenging radicals. Studies indicate that resveratrol supplements may be particularly important for those at risk for Alzheimer’s, or those who have it. It is theorized that free radicals might initiate the process that leads to the disease. Research has uncovered a diverse range of activities that may make resveratrol one of the most useful agents ever discovered for a wide range of human health problems. Many more discoveries has made this compound an essential component of the time.

Honeysuckle and its uses

Honeysuckle is a kind of shrub which comes from the family 'Caprifoliaceae'. Its mostly native to the northern hemisphere with around 100 species found in China itself. Some widely known species of honeysuckle are Lonicera periclymenum, Lonicera japonica and Lonicera sempervirens.

The main active ingredients of the honeysuckle extract is chlorogenic acid (chlorogenic acid, CGA) and luteolin glycosides (Luteolin). The CGA of honeysuckle can be used in the preparation of drugs, health products and cosmetic's raw materials. Honeysuckle Flowers Extract has anti-inflammatory and anti-bacterial properties which enhances the immune function. It has relatively lower toxicity level and low side-effects.

To administer this anti-inflammatory and anti-pyretic effect a test was conducted on a rat. One such test revealed that Intraperitoneal injection of honeysuckle extract liquid measured 0.25g/kg can inhibit the rat carrageenan sexual swollen feet. Another analysis report concluded that the honeysuckle Injection of 30-40g/kg can reduce the degree of egg white swollen feet. In the next test Intraperitoneal injection of honeysuckle extract liquid measured 8g/kg was given twice a day for six consecutive days and was found that it also has significant anti-exudative and anti-proliferative effect. Early reports on honeysuckle revealed obvious antipyretic effect to the rabbit ear vein injection of cholera vaccine.

It has many significant usefulness. Honeysuckle is sometimes applied to the skin for inflammation and itching to kill germs. It is also used as honeysuckle tea as a home remedy for exhaustion and heat stroke. These various beneficiary properties proves how valuable a honeysuckle shrub could be.
