     Naringin Naringin

The source of the plant Citus paradisi Macfadyen

Pharmacology functionIt can reduce Blood fat and liver fat, and also has the function of sedation. Naringin is also the component of the medicine which curse diabetes. Naringin is related to other flavanones known to have therapeutic action in influencing capillary permeability. For those pharmaceutical uses the better solubility of naringin in water is an advantage.

Studies have shown that naringin interferes with enzymatic activity in the intestines and, thus, with the breakdown of certain drugs, resulting in higher blood levels of the drug. A number of drugs that are known to be affected by the naringin in grapefruit include calcium channel blockers, estrogen, sedatives, medications for high blood pressure, allergies, AIDS, and cholesterol-lowering drugs. Caffeine levels and effects of caffeine may also be extended by consuming grapefruit or grapefruit juice. While the effect of naringin on the metabolism of a drug can increase the drug's effectiveness, it can also result in dosages that are inadvertently too high. Therefore, it's best not to take any drugs with grapefruit juice unless the interaction with the drug is known. In addition, the effects of drinking grapefruit juice is cumulative, which means that if you drank a glass of grapefruit juice daily with your medication for a week, the drug interaction would be stronger at the end of the week than at the beginning Naringin can be used as an intermediate in the synthesis of many organic chemicals.
