One of the alternative medicines to both diabetes and obesity could be G. sylvestrae plant preparation, as it known to have a good effect for curbing of diabetes by blocking sugar binding sites and hence not allowing the sugar molecules to accumulate in the body.
Gymnema Sylvestre is regarded as one of the plants with potent anti diabetic properties. This plant is also used for controlling obesity in the form of Gymnema tea. The active compound of the plant is a group of acids termed as gymnemic acids. It has been observed that there could be a possible link between obesity, Gymnemic acids and diabetes. This review will try to put forth an overall idea about the plant as well as present a molecular perspective linking the common medicine to the most common metabolic disorders.
Gymnemic acid formulations have also been found useful against obesity, according to recent reports. This is attributed to the ability of gymnemic acids to delay the glucose absorption in the blood. The atomic arrangement of gymnemic acid molecules is similar to that of glucose molecules. These molecules fill the receptor locations on the taste buds thereby preventing its activation by sugar molecules present in the food, thereby curbing the sugar craving. Similarly, Gymnemic acid molecules fill the receptor location in the absorptive external layers of the intestine thereby preventing the sugar molecules absorption by the intestine, which results in low blood sugar level.
Gymnema leaf extract, notably the peptide 'Gurmarin', has been found to interfere with the ability of the taste buds on the tongue to taste sweet and bitter. Gymnemic acid has a similar effect. It is believed that by inhibiting the sweet taste sensation, people taking it will limit their intake of sweet foods, and this activity may be partially responsible for its hypoglycemic effect.
There are some possible mechanisms by which the leaves and especially Gymnemic acids from G. sylvestrae exert its hypoglycemic effects are:
