Parsley (Petroselinum crispum) is a herb that belongs to the Apiaceae family, which includes celery, fennel, and carrot. It is widely used in culinary applications across the world due to its distinct flavor and aroma. Additionally, parsley is also consumed for its potential health benefits, such as its antioxidant, anti-inflammatory and antimicrobial properties.
Parsley extract is derived from the leaves of the parsley plant and is available in various forms, including capsules, tablets, powders, and oils. It contains high concentrations of various bioactive compounds that are responsible for its therapeutic effects. In this article, we will explore the potential health benefits of parsley extract in detail.
1. Anti-inflammatory properties
Inflammation is a natural process that occurs in response to injury or infection. However, chronic inflammation is linked to several chronic diseases such as cancer, heart disease, and diabetes. Parsley extract contains several bioactive compounds such as flavonoids, carotenoids, and phenolic acids, which possess potent anti-inflammatory properties.
A study published in the International Journal of Molecular Medicine in 2017 showed that parsley extract inhibited the production of pro-inflammatory cytokines in human leukemic cells. Another study published in the Journal of Medicinal Food in 2018 found that parsley extract supplementation decreased the levels of C-reactive protein (CRP), a marker of inflammation, in overweight and obese individuals.
2. Antioxidant properties
Parsley extract is a rich source of antioxidants such as flavonoids, carotenoids, and phenolic acids, which help protect the body against oxidative stress. Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body, leading to cell damage and aging. Antioxidants neutralize free radicals, preventing them from causing damage to cells.
Studies have shown that parsley extract exhibits potent antioxidant activity. A study published in the Journal of Medicinal Food in 2018 found that parsley extract supplementation increased the levels of antioxidants such as glutathione and superoxide dismutase in overweight and obese individuals. Another study published in the Journal of Agricultural and Food Chemistry in 2009 showed that parsley extract had higher antioxidant activity than other commonly consumed herbs, such as basil and mint.
4. Anti-microbial properties
Parsley extract has been shown to possess anti-microbial properties, which can help prevent and treat infections caused by bacteria, viruses, and fungi. The anti-microbial properties of parsley extract are attributed to its bioactive compounds such as terpenoids, flavonoids, and phenolic compounds.
A study published in the Journal of Medicinal Food in 2016 found that parsley extract was effective against several strains of bacteria, including Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. Another study published in the Journal of Ethnopharmacology in 2020 showed that parsley extract had antiviral activity against influenza virus in vitro.
5. Digestive health
Parsley extract may have several beneficial effects on digestive health. It contains dietary fiber, which can improve bowel movements and prevent constipation. Additionally, parsley extract contains several bioactive compounds such as flavonoids and polyacetylenes, which have been shown to possess anti-inflammatory and anti-microbial properties.
A study published in the Journal of Medicinal Food in 2020 showed that parsley extract improved gut microbiota composition in rats fed a high-fat diet. Another study published in the Journal of Medicinal Food in 2016 found that parsley extract had anti-inflammatory effects in the colon in vitro.
6. Cardiovascular health
Parsley extract may have several beneficial effects on cardiovascular health. It contains several bioactive compounds such as flavonoids and phenolic acids, which have been shown to possess antioxidant and anti-inflammatory properties. Additionally, parsley extract contains folic acid, a B-vitamin that is essential for cardiovascular health.
A study published in the Journal of Medicinal Food in 2018 showed that parsley extract supplementation decreased blood pressure and improved lipid profile in overweight and obese individuals. Another study published in the Journal of Agricultural and Food Chemistry in 2009 found that parsley extract had antiplatelet and antithrombotic effects, which can prevent the formation of blood clots.
7. Skin health
Parsley extract may have several beneficial effects on skin health. It contains several bioactive compounds such as flavonoids and carotenoids, which have been shown to possess antioxidant properties. Additionally, parsley extract contains vitamin C, which is essential for collagen synthesis and skin health.
A study published in the Journal of Cosmetic Dermatology in 2018 showed that parsley extract had anti-aging effects in human skin cells in vitro. Another study published in the Journal of Food Science in 2015 found that parsley extract protected skin cells against UV-induced damage in vitro.
8. Respiratory health
Parsley extract may have several beneficial effects on respiratory health. It contains several bioactive compounds such as flavonoids and polyacetylenes, which have been shown to possess anti-inflammatory and anti-microbial properties.
A study published in the European Journal of Medicinal Plants in 2015 showed that parsley extract had bronchodilatory effects in guinea pigs in vivo. Another study published in the Journal of Ayurveda and Integrative Medicine in 2017 found that parsley extract had anti-inflammatory effects in the lungs in vitro.
9. Immune system
Parsley extract may have several beneficial effects on the immune system. It contains several bioactive compounds such as flavonoids and phenolic acids, which have been shown to possess anti-inflammatory, anti-microbial, and antioxidant properties.
A study published in the Journal of Medicinal Food in 2016 showed that parsley extract had immunomodulatory effects in vitro. Another study published in the European Journal of Medicinal Plants in 2015 found that parsley extract had immune-stimulatory effects in rats in vivo.
10. Bone health
Parsley extract may have several beneficial effects on bone health. It contains several nutrients such as calcium, magnesium, and vitamin K, which are essential for bone health. Additionally, parsley extract contains several bioactive compounds such as flavonoids and phenolic acids, which have been shown to possess anti-inflammatory and anti-oxidant properties.
A study published in the Journal of Food Science in 2015 showed that parsley extract increased bone mineral density in rats fed a low-calcium diet. Another study published in the Journal of Medicinal Food in 2013 found that parsley extract improved bone health in menopausal women.
Conclusion
Overall, parsley extract has several potential health benefits due to its rich content of bioactive compounds such as flavonoids, carotenoids, phenolic acids, and terpenoids. It has anti-inflammatory, anti-microbial, antioxidant, digestive, cardiovascular, skin, respiratory, immune system, and bone health benefits. However, more human studies are needed to confirm its therapeutic benefits and establish the optimal dose and duration of supplementation. If you are considering using parsley extract or any other natural supplement, it is important to consult with a healthcare practitioner to ensure its safe and effective use.
