Dandelion leaves can play an essential role in improving liver health. Dandelion leaves are a rich source of vitamin A in the form of antioxidant beta carotene and vitamin C.
According to a 2010 study, when researchers gave rats with hepatitis dandelion leaf extracts, it prevented oxidative damage and damage to the liver (2).
Further studies have also proved that anti-oxidant foods like dandelion greens even treat and prevent oxidative damage caused by free radicals (3).
2. Improve eye health
Dandelion leaves are rich in lutein and zeaxanthin, two nutrients that are important for maintaining healthy eyesight. These nutrients filter the light as it enters the eye and protects eye tissue from any damage.
According to the American Optometric Association, consuming at least 12 mg of lutein and zeaxanthin lowers the risk of age-related macular degeneration(AMD) and cataract.
Dandelion greens are also rich in vitamin A, which is very important for eye health. A deficiency in vitamin A can also lead to blindness.
In addition to vitamin A, dandelion leaves also contain vitamin C and E, all of which are important for reducing the risk of age-related macular degeneration.
According to a 2005 study, a high dietary intake of beta-carotene, vitamin C, vitamin E, and zinc, can substantially reduce the risk of age-related macular degeneration (4).
Dandelion greens are a natural diuretic. They have been traditionally used to increase the amount of urine to eliminate fluids from the body, which is helpful for people with liver problems and high blood pressure.
It also helps in reducing water weight and preventing urinary tract infections.
During a 2009 study, volunteers were given fresh dandelion greens extract to investigate whether it would increase urinary frequency and volume.
The results showed a significant increase in the frequency of urination in the five hours after the first dose (5).
4. Aid weight loss
Like all leafy greens, dandelion leaves are also low in calories. One cup of chopped dandelion leaves contains only 25 calories. These leaves are also a rich source of fiber, which can promote satiety and help in weight loss.

Elevated blood triglyceride is a common lipid disorder in America. Triglycerides are a fatty substance present in the bloodstream. High levels of triglycerides can lead to atherosclerosis and can significantly increase the risk of heart attack.
Dandelion greens reduce the activity of pancreatic lipase, the enzyme that breaks triglycerides down into fatty acids. This helps in increasing the excretion of triglycerides and which helps lower the blood triglyceride levels.
