Hawthorn is a plant. The leaves, berries, and flowers of hawthorn are used to make medicine.
Hawthorn is used for diseases of the heart and blood vessels such as congestive heart failure (CHF), chest pain, and irregular heartbeat. It is also used to treat both low blood pressure and high blood pressure, “hardening of the arteries” (atherosclerosis), and high cholesterol. So far, research suggests that hawthorn might be effective in treating congestive heart failure, but there hasn’t been enough research on other heart-related uses to know if it is effective for them.
Some people use hawthorn for digestive system complaints such as indigestion, diarrhea, and stomach pain. It is also used to reduce anxiety, as a sedative, to increase urine output, and for menstrual problems.
Hawthorn is also used to treat tapeworm and other intestinal infections.
Some people apply hawthorn to the skin for boils, sores, and ulcers. Hawthorn preparations are used as a wash for sores, itching, and frostbite.
