Approximately 5 years ago, after a stress test, a cardiologist diagnosed a heart murmur and told me not to worry and prescribed a sennoside tablet to lower blood cholesterol. Now I'm reading said sennosides can cause both high blood cholesterol and high blood pressure. Any suggestions. I'm a 61 year old female, good health generally, sometimes good blood pressure, sometimes in higher ranges (when high usually around 140/90 range.)
