Crataegus douglasii and Cardiovascular Effects
83
Crataegus douglasii, a specimen known as Black Hawthorn, exhibits medicinal properties that affect the cardiovascular system. This specimen belongs to the Rosaceae family. Throughout history, Crataegus douglasii has been used to help protect against heart disease, high cholesterol, and high blood pressure. Studies have further shown that Crataegus douglasii may improve circulation, lower blood pressure, and increase coronary artery blood flow overall. - By Anaeli Guzman and Salma Fawzi

Crataegus douglasii is a specimen with small light green leaves, thin green-brown branches, and black dried-up flowers. At first glance, individuals may notice the multiple black pieces on the plant and wonder about the type of flowers Crataegus douglasii exhibits when the flowers bloom. Black Hawthorn’s leaves furthermore have great detail.
From the UCLA Herbarium, Crataegus douglasii was collected by Carl Epling in June 1927 in Santa, Idaho. It is part of the Rosaceae family and the coordinates of the plant were located between 47.151097 and -116.449687 with an elevation of 300 meters. Researchers likely traveled and hiked to specified regions to be able to collect this specimen.
Another image of Black Hawthorn was produced in August 1992. Emmet J. Judziewicz depicted the plant in a beautiful manner. The plant was spread out with its black flowers attached. A reason behind this image was to add to research supported by the National Park Service and the University of Wisconsin-Madison Herbarium fund. The role of this image contributed to the collection, identification, and classification of Crataegus douglasii by building up the data on Black Hawthorns. Overall, the addition of this image illustrates the progression and identification of Crataegus Douglasii through the lens of a collector.
Crataegus douglasii has been used to help protect against heart disease and help control high cholesterol and high blood pressure. Different studies have shown that Crataegus douglasii seems to improve circulation, lower blood pressure, and increase coronary artery blood flow. It has also been used to treat boils and skin sores. This plant contains different flavonoids, such as rhamnosides and schaftosides. Flavonoids are phytonutrients found in almost all fruits and vegetables that have anti-inflammatory effects and protect cells from oxidative damage that can lead to disease. Because of the flavonoids, Crataegus douglasii has a positive inotropic effect on the heart by strengthening the force of the heartbeat.
The specimen has leaves that are broad, long, and serrated at the tip. It has dense clusters of white flowers in the spring and edible fruits that mature to black in late summer. Its flowers have an unpleasant fragrance which tends to attract pollinators such as midges and butterflies. Crataegus douglasii can also be planted for erosion control. This specimen is self-fertile, meaning that both male and female parts can be found on the same plant. The best method of propagating Crataegus douglasii is through seeds and wind dispersal. It is native to wetlands, open moist places, bluffs and slopes, meadows, ditches, and along streams in a large geographic territory. It is most commonly found in the Pacific Northwest.
Crataegus douglasii relates to the main theme of cardiovascular effects. These effects include anti-inflammatory response, protection against hypertension, treatment of infection, antihypertensive, and antibacterial properties. These medicinal properties overlap with other specimens that affect the cardiovascular system, and further research is needed to link the similarities of effects on the cardiovascular system as a connection between Crataegus douglasii and other specimens.

Bidens pilosa, Crataegus douglasii, and Urtica dioica effects on Cardiovascular System
33
Bidens pilosa, Crataegus douglasii, and Urtica dioica are medicinal plants that have been found to contain a myriad of bioactive compounds, such as flavonoids, antioxidants, and polyphenol compounds which are known to have significant effects on the cardiovascular system primarily targeting systolic hypertension. Plant extracts and its derivatives ameliorate oxidative stress, hyperlipidemia, hypertension that are associated with cardiovascular disease due to their anti-inflammatory, vasorelaxant, antiviral activity that are elicited to prevent the onset of cardiovascular diseases risk factors. Cardioprotective effects and health benefits of Bidens pilosa, Crataegus douglasii, and Urtica dioica will be discussed. - By Salma Fawzi, Anaeli Guzman, Rere Huang, Lilliane Martin, Isabel Nakoud, and Sriha Srinivasan

The three specimens known as Bidens pilosa, Crataegus douglasii, and Urtica dioica all exhibit medicinal properties that have an immense effect on the cardiovascular system. Some of these effects include anti-inflammatory responses, protection against hypertension, treatment of infections, antihypertensive, and antibacterial properties. Amongst the overlapping medicinal properties in Bidens pilosa, Crataegus douglasii, and Urtica dioica, is an understanding of how the plants play a role in numerous cardiovascular processes.
Crataegus douglasii has been used to help protect against heart disease and help control high cholesterol and high blood pressure. Different studies have shown that Crataegus douglasii seems to improve circulation, lower blood pressure, and increase coronary artery blood flow. It has also been used to treat boils and skin sores.

Flavonoids are phytonutrients found in almost all fruits and vegetables that have anti-inflammatory effects and protect cells from oxidative damage that can lead to disease.

It is native to wetlands, open moist places, bluffs and slopes, meadows, ditches, and along streams in a large geographic territory. It is most commonly found in the Pacific Northwest.
Urtica dioica subspecies Holoser., or stinging nettle has been used in traditional medicine for centuries. Its leaves are initially hostile, but can be cooked similar to a vegetable for both nutritional and medical value. The leaves can also be burned into a tea, producing a health tonic filled with flavonoids. As aforementioned, flavonoids have cardiovascular properties, and the tonic is also anti-bacterial and anti-inflammatory. U. dioica can produce hypotensive responses, through a vasorelaxant effect mediated by the release of endothelial nitric oxide and the opening of potassium channels, and through negative inotropic action. It can also be turned into a pulp and used externally as a poultice. There are claims that it helps with eczema, urinary tract problems, and cardiovascular benefits, but these claims are less substantiated than health claims related to internal consumption.The plant itself has leaves rich in cellulose, polyphenol compounds, vitamin C, and minerals. They are high in fiber and can be used within basic construction. The stinging nettle can self-reproduce, as it grows with both male and female reproductive organs. It also spreads easily within its locality, with widely spreading rhizomes and stolons. In fact, it is often planted to reduce soil erosion and help the environment in which it is planted. However, it is native to subtropical and tropical Asia, and is common especially in China. However, it can still be found in the North Americas, particularly on the West Coast. Here, hikers often see stinging nettle on trails or bordering neighborhoods, as the name ‘stinging’ implies less danger than what is actually to be feared.
Historically, Bidens pilosa has been used to treat over forty diseases and disorders including inflammation, immunological disorders, digestive disorders, infectious diseases, cancers, metabolic syndromes, and wounds. However, in addition to these common medicinal uses, the bioactive compounds produced by Bidens pilosa have also proven rather useful in the treatment of cardiovascular diseases. This includes lowering systolic blood pressure, reducing cardiac hypertrophy, and the potential to treat cardiovascular diseases such as atherosclerosis and coronary artery disease. Bidens pilosa is rich in phytochemicals such as polyynes, flavonoids, phenylpropanoids, and phenolics that in addition to treating tumors, inflammation, diabetes, viruses, microbes, and gastrointestinal diseases, have also been found effective in treating cardiovascular diseases. Flavonoids, in particular, present many potential cardiovascular health-promoting properties. Bidens pilosa is rich in flavonoid compounds, with evidence of over 60 different flavonoids being produced by the plant. These flavonoids include bioflavonoids and quercetin derivatives which exhibit antioxidant properties that function to reduce the harmful impact of free radicals in the body. Through a series of chemical reactions, free radicals, derived from metabolic processes or through an outside source such as pollutants or chemicals, damage cellular components leading to an increased risk for the development and further progression of cardiovascular diseases. Medical research has found that extracting these flavonoids and constituting them with acetate, butanol, and water creates free radical scavengers, substances functioning to protect cells from damage caused by free radicals. In addition, the plant is rich in essential oils, these essential oils contain compounds such as monoterpenes and phenolics believed to have anti-hypertensive properties.WORKS CITED
