Crataegus leaf extract has become an extremely popular herb in Europe because of its very beneficial influence on hypertension (high blood pressure), hyperlipemia (high blood fat) and high cholesterol. In China it is combined with Cassia tora seed and or Gynostemma leaf to improve this function and may be consumed as a tea or in capsules. Crataegus leaf extract can be used to treat symptoms of coronary heart disease, especially when combined with herbs that improve circulation, such as Salvia, Pseudoginseng, Ginkgo and Ligusticum.
