Hawthorn, Also Called Haw, or Thornapple,

Hawthorn, also called Haw, or Thornapple, can be any of a number of thorny shrubs or small trees of the genus Crataegus, in the rose family (Rosaceae), native to the North Temperate Zone.
Many species are native to North America and the fruits or haws are edible. The taste however can vary greatly depending on the species, particular tree, time of year and growing conditions. The haws are usually rather seedy, with the flavour described as a range of sweet, mealy, insipid, bitter, astringent, or even tasteless. As is usual with berries, frosts are known to increase the w=sweetness of the haws.
Historically, these berries were eaten fresh from the tree, or dried for winter use. They were often an addition to pemmican. The cooked pureed pulp (with the seeds removed) was dried and stored in cakes as berry-bread, which could be added to soup, or eaten with venison fat or marrow.
Haws are rich in pectin and if boiled with sugar can be a useful aid in getting jams and jellies to set without having to use a commercial product. Like rose hips to which they look very similar(THEY ARE IN THE ROSE FAMILY) can be steeped to make a pleasing tea or cold beverage.
The haws of English hawthorn are commonly called “Bread and Butter Berries” in the UK, likely because of the starchy and somewhat creamy texture of the fruit.
HAWTHORN FLOWERS AND FRUITS ARE FAMOUS IN HERBAL MEDICINE AS HEART TONICS THOUGH NOT ALL SPECIES ARE EQUALLY EFFECTIVE.
Description:
The hawthorn’s leaves are simple, and usually toothed or lobed. The white or pink flowers, usually in clusters, are followed by small apple like, red fruits, or more rarely by blue or black ones. Many cultivated varieties of hawthorn are now grown as ornamentals for their attractive flowers and fruits. Some species are characterized by horizontal branching, a growth habit considered to enhance their ornamental value.
Overview
Hawthorn (Crataegus species) has been used to treat heart disease as far back as the 1st century. By the early 1800s, American doctors were using it to treat circulatory disorders and respiratory illnesses. Traditionally, the berries were used to treat heart problems ranging from irregular heartbeat, high blood pressure, chest pain, hardening of the arteries, and heart failure. Today, the leaves and flowers are used medicinally, and there is some research that suggests that hawthorn might be effective when used in the treatment of mild to moderate heart failure, but there has not been enough research to know how effective it may be.
Animal and laboratory studies report hawthorn contains antioxidants, including oligomeric procyandins (OPCs, also found in grapes) and quercetin. Antioxidants are substances that destroy free radicals -- compounds in the body that damage cell membranes, tamper with DNA, and even cause cell death. Free radicals occur naturally in the body and grow in number as we age. Environmental toxins (including ultraviolet light, radiation, smoking, some medicines, and air pollution) can also increase the number of these damaging particles. Free radicals are believed to contribute to the aging process (such as wrinkling), as well as the development of a number of health problems, including cancer and heart disease. Antioxidants found in hawthorn may help stop some of the damage from free radicals, especially when it comes to heart disease.
Plant Description
Hawthorn is a common thorny shrub in the rose family that grows up to 5 feet tall on hillsides and in sunny wooded areas throughout the world. Its flowers bloom in May. They grow in small white, red, or pink clusters. Small berries, called haws, sprout after the flowers. They are usually red when ripe, but they may also be black. Hawthorn leaves are shiny and grow in a variety of shapes and sizes.
What's It Made Of?
Hawthorn contains many substances that MAY benefit the heart. These antioxidant flavonoids -- including OPCs -- may help dilate blood vessels, improve blood flow, and protect the blood vessels from damage.
The berries, leaves, and flowers of the hawthorn plant have been used for medicinal purposes. Most modern preparations use the leaves and flowers, which are believed to contain more of the flavonoids than the berries.
Medicinal Uses and Indications
Hawthorn is used to help protect against heart disease and help control high blood pressure and high cholesterol. Both, animal and human studies suggest hawthorn increases coronary artery blood flow, improves circulation, and lowers blood pressure. It has also been used on the skin to treat boils and skin sores.
Heart failure
Hawthorn has been studied in people with heart failure (a condition in which the heart is unable to pump enough blood to other organs in the body), but more studies are needed to understand how effective it may be. A number of studies conclude that hawthorn significantly improved heart function. Studies also suggest the herb can enhance a person's ability to exercise following heart failure. Participants in studies have reported that hawthorn significantly improved symptoms of the disease (such as shortness of breath and fatigue). One study found that hawthorn extract (900 mg/day) taken for 2 months was as effective as low doses of captopril (a prescription heart medication) in improving symptoms of heart failure.
A large study found that a standardized hawthorn supplement was effective in 952 patients with heart failure. The study compared conventional methods of treating heart failure (with different medications) with hawthorn alone and in addition to the drugs. After 2 years, the clinical symptoms of heart failure (palpitations, breathing problems, and fatigue) decreased significantly in the patients taking the hawthorn supplement. People taking hawthorn also took less medication for their condition.
Heart failure is a serious condition, and you should never try to self-treat with hawthorn. Ask your doctor if hawthorn is right for you.
Chest pain (Angina)
Preliminary evidence suggests hawthorn may help combat chest pain (angina), which is caused by low blood flow to the heart. In one early study, 60 people with angina were given either 180 mg/day of hawthorn berry leaf flower extract or placebo for 3 weeks. Those who received hawthorn experienced improved blood flow to the heart and were also able to exercise for longer periods of time without suffering from chest pain. However, more studies are needed to say for sure whether hawthorn is effective.
High blood pressure
Although hawthorn has not been studied specifically in people with high blood pressure, some people think its benefits in treating heart disease may carry over to treating high blood pressure (hypertension). However, so far not enough research has been done to say whether hawthorn is effective at lowering blood pressure -- and if so, by how much.
In one study, hawthorn extract was found to be effective for hypertension in people with type 2 diabetes who were also taking prescribed medicines. Participants took 1,200 mg hawthorn extract daily or placebo for 16 weeks. Those taking hawthorn had lower blood pressure than those taking the placebo.

You should talk with your doctor before taking hawthorn if you have high blood pressure.
