Gymnema Herbal Tea for Diabeties

Gymnema Herbal Tea for Diabeties:

Gymnema Sylvestre is a woody, vine-like plant which climbs on bushes and trees. The medicinally active parts of the plant are the leaves and the roots. It came to be known as "destroyer of sugar" because,in ancient times, Ayurvedic physicians observed that chewing a few leaves of Gymnema sylvestre suppressed the taste of sugar. That is, sweet foods no longer tasted sweet, but rather became almost completely tasteless. In later generations, clinical tests showed that regular use over a period of three to four months helped to reduce glycosuria, or the appearance of carbohydrates in urine. Recent clinical trials conducted in India have shown that an extract of Gymnema sylvestre is useful for controling Blood Sugar.

As a result of these clinical tests and years of successful treatments, Gymnema sylvestre is used today for controling blood sugar levels. In reducing the symptom of glycosuria, the dried leaves are used in daily doses of three to four grams for a period of three months or more.

Studies conducted in India as early as 1930 showed that the leaves of Gymnema sylvestre cause hypoglycemia in experimental animals. This state of hypoglycemiais explained on the assumption that the drug indirectly stimulates the insulin secretion of the pancreas, since it has no direct effect on the carbohydrate metabolism.
How Gymnema sylvestre Works
Recent pharmacological and clinical studies have shown that Gymnema sylvestre acts on two sites:

* First, the taste buds in the oral cavity;
* Second, the absorptive surface to the intestines.

The structure of those taste buds which detect sugar in the mouth is similar to the structure of the tissue that absorbs sugar in the intestine. The important active ingredient of Gymnema sylvestre is an organic acid called "gymnemic acid." The gymnemic acid is made up of molecules who seatom arrangement is similar to that of glucose molecules. Those molecules fill the receptor locations on the taste buds for a period of one to two hours, thereby preventing the taste buds from being activated by any sugar molecules present in the food. Similarly, the glucose-like molecules in the gymnemic acid fill the receptor locations in the absorptive external layers of the intestine, thereby preventing the intestine from absorbing the sugar molecules.

It has also been noted that Gymnema sylvestre takes away the bitter taste of bitter substances, such as quinine, in much the same way that it affects the sense of sweetness associated with candies and other sweet foods. However, it has no effect on pungent, salty, astringent or acidic tastes. Therefore, if you are eating an orange within two hours after chewing Gymnema sylvestre leaves, for instance, you would taste the sourness of it but not the sweetness.
Practical Uses
# The benefits of Gymnema sylvestre are two-fold: By suppressing the taste of sweet foods, the desire to eat them is also suppressed. Picture a luscious-looking large piece of chocolate candy, which you know, despite the tempting look, is not sweet. Why bother to eat it? It is important to remember that this effect of Gymnema sylvestre's will last for only one to two hours. If you are using the herb to break the sugar habit, then it would be wise to take some Gymnema sylvestre before social events or other times when you might be tempted to dive into the tray of sweets.
# Gymnema sylvestre significantly reduces the metabolic effects of sugar by preventing the intestines from absorbing the sugar molecules during the process of digestion. Because there is a change in the absorption of sugar, there is a consequent change in the blood sugar level.
