Herbs and heart - bitter orange
In this eByte, it’s herbs and safety as it relates to the heart.
It’s a widespread belief that if something is natural, meaning it exists in nature… It’s safe. It can’t harm you. Some product manufacturers associate their natural products with this safety.
Many widely prescribed medications are derived from plants. This includes metformin for type two diabetes and lovastatin for high cholesterol.
In the United States, dietary supplements are not regulated the way pharmaceutical drugs are. And many contain herbs.
So, a study looked at the reports over a 50 year period regarding individual herbs and the heart…
Bitter orange is an extract derived from citrus plants. It contains an active compound called synephrine. ￼
It’s widely found in weight loss products.
It increases heart rate and blood pressure and for some people has led to cardiovascular problems including heart attack.
When taken in low doses, Synephrine is largely safe. A single cup of orange juice contains 25 to 40 mg. However, weight loss supplements can be as high as 500 mg. ￼
