Hawthorn Pills Safe for Heart Patients
Hawthorn Extract May Extend Lives of Heart Failure Patients, Though Further Study Needed
March 27, 2007 (New Orleans) -- An herbal supplement taken to relieve symptoms of heart failure is safe when taken with other common heart drugs, German researchers report.
Their new study also suggested that the pills, known as hawthorn or crataegus extract, may help to extend the lives of people suffering form heart failure -- at least in the short term.
But by two years, equal numbers of people given the supplement and placebo had died, says Christian J. F. Holubarsch, MD, of Median Kliniken Hospitals in Bad Krozingen, Germany.
"We can't yet say it saves lives," Holubarsch tells WebMD. "But the data are promising and are worthy of further study."
The study was presented at the annual meeting of the American College of Cardiology.
Hawthorn Extract Relieves Heart Failure Symptoms
Holubarsch says that extracts made from the leaves of hawthorn, a shrub commonly found in Europe, western Asia, North America, and North Africa, have been used for years to relieve minor heart failure symptoms such as breathlessness and fatigue.
The new study, he says, is the first to look at the effectiveness and safety of the extract when given to more severe heart failure patients.
Heart failure is a condition in which the heart can't pump blood effectively to the lungs or the rest of the body. This is usually because of damage to the heart muscle, such as damage from a previous heart attack.
The extract is a natural antioxidant that combats oxidative stress, a condition in which the body essentially has too many free radicals -- the waste products that result from all the chemical reactions occurring in the body.
