Crataegus is considered to be particularly helpful for:
Protecting the heart
Relieving insomnia or nervousness
Reducing total cholesterol
Managing anxiety and mental stress
It is possible that Crataegus may have some unwanted effects when taken for a long period of time, in combination with blood pressure medication, during pregnancy, and should be discontinued at least two weeks before scheduled surgery.
Herbs cannot replace medical treatment and you should ALWAYS follow your doctor's advice
