| Arjuna |
| Arjun or Terminalia arjuna (TA) is a unique herb that helps maintain a healthy heart and reduces the effects of stress and nervousness. Arjun promotes effective cardiac functioning and regulates blood pressure. Arjun has been the herb of choice in Ayurveda for cardiovascular health. Arjun’s ability to suppress the blood’s absorption of lipids indicates that it has cholesterol-regulating properties. Its principal constituents are §-sitosterol, ellagic acid, and arjuna acid.The bark of Arjun is useful as an anti-ischemic and cardioprotective agent in hypertension and in ischemic heart disease, especially in disturbed cardiac rhythm, angina, or myocardial infarction. The bark powder possesses diuretic and a general tonic effect in cases of cirrhosis of the liver, in addition to prostaglandin enhancing and coronary risk factor modulating properties. It induces a drug-dependent decrease in blood pressure and heart rate.
Recent studies have investigated the mechanism of this activity and have shown a dose-dependent regulation of blood pressure and heart rate. There was also a slight increase in the HDL-to-total cholesterol ratio and an overall improvement in the cardiovascular profile. The bark of Arjun inhibits the oxidation of LDL and accelerates the turnover of LDL-cholesterol in the liver. This enhances the elimination of cholesterol from the body. The suppression of hepatic cholesterol biosynthesis by Terminalia arjuna is the mechanism responsible for a significant lowering of beta-lipoprotein lipids and the recovery of HDL components in hyperlipidemia. In a study on the efficacy of bark powder in treating congestive cardiac failure (CCF), over 40% of the cases showed marked improvement. CCF due to congenital anomaly of heart and valve disease was also brought under control. 4 out of 9 cases of CCF due to chronic bronchitis were also relieved by the treatment. Arjuna is also known to relieve symptomatic complaints of essential hypertension viz. giddiness, insomnia, lassitude, headache, and the inability to concentrate. Oral administration of an aqueous suspension of the bark powder reduces coagulation, bleeding and prothrombin time. In summary, the traditional uses for Arjun have been: 1. Reduces the effects of stress and nervousness on the heart Possesses diuretic and a general tonic effect in cases of liver cirrhosis |
