Effects of dandelion

Dandelion leaves, roots, and flowers may offer health benefits. These may include supporting liver health and fighting inflammation. Although it is often considered a stubborn weed, people have used dandelion in traditional medicine for centuries.

The leaves, roots, and flowers can not only add color to your plate, but are also often found in herbal teas and supplements, where they are used as natural remedies to regulate blood sugar levels and support the health of the skin, liver, and heart.

Here are 13 potential health benefits of dandelion, along with common risks and side effects.

1. Highly nutritious

From root to flower, dandelion is an exceptionally nutritious plant, packed with vitamins, minerals, and fiber.

Dandelion greens can be eaten cooked or raw and are an excellent source of vitamins A, C, and K. They also contain vitamin E, folate, and small amounts of other B vitamins. Dandelion greens contain several minerals, including iron, calcium, magnesium, and potassium.

Dandelion root is rich in inulin, a soluble fiber found in plants that supports the growth and maintenance of healthy gut bacteria in the digestive system.

Dandelion root is often dried and used to make tea, but you can also eat it whole, like other root vegetables.

SUMMARY Dandelion’s nutrient content extends throughout the plant. Dandelion is rich in fiber, as well as several vitamins and minerals.

2. Contains powerful antioxidants

Dandelion contains powerful antioxidants, which may explain many of its medicinal properties.

Antioxidants are compounds that help neutralize free radicals—molecules that are byproducts of normal metabolism but contribute to the risk of chronic diseases when their levels are too high in the body. Therefore, antioxidants are crucial to your overall health.

Dandelion contains large amounts of the antioxidant beta-carotene, which may protect against cell damage and oxidative stress.

They are also rich in another type of antioxidant, called polyphenols, which are found mainly in the flower but also occur in the roots, leaves, and stem.

SUMMARY Dandelion is a rich source of beta-carotene and polyphenolic compounds, both of which may neutralize harmful free radicals and protect against chronic diseases.

3. May Help Fight Inflammation

Dandelion may reduce inflammation thanks to compounds such as polyphenols.

Inflammation is the immune system’s natural response to injury or infection. However, long-term inflammation can continually damage body tissues and DNA.

Some test-tube studies found significantly reduced inflammatory markers in cells treated with compounds extracted from dandelion.

A study in rats found that a tincture made from dandelion reduced oxidative stress and had cardioprotective effects.

Nevertheless, human research is needed.

SUMMARY A limited number of animal and test-tube studies suggest that dandelion has anti-inflammatory properties, although human studies are lacking.

4. May Help Manage Blood Sugar Levels

Chicory and chlorogenic acid are two bioactive compounds in dandelion that may help reduce blood sugar levels.

Test-tube and animal studies show that these compounds may improve the secretion of insulin — a hormone that regulates blood sugar levels — and the absorption of glucose (sugar) in muscles.

This process improves insulin sensitivity and reduces blood sugar levels.

Chicory and chlorogenic acid may also limit the digestion of starchy, high-carbohydrate foods, which may further contribute to dandelion’s ability to reduce blood sugar levels.

Although these results are promising, more research in humans is needed.

SUMMARY Dandelion contains bioactive compounds that have been shown to reduce blood sugar levels in animal and test-tube studies. However, human research is still needed.

5. May Reduce Cholesterol and Triglyceride Levels

Certain compounds in dandelion may reduce triglyceride and cholesterol levels, which are key risk factors for heart disease.

Some polyphenols found in dandelion, such as flavonoids and hydroxycinnamic acid derivatives, may have cholesterol- and triglyceride-lowering properties.

Another review noted that dandelion may have heart-protective effects, including reducing cholesterol levels.

However, current research is limited to test-tube and animal studies, and human studies are needed.

SUMMARY Some animal studies indicate that dandelion lowers cholesterol and triglyceride levels, but research in humans is needed.

6. May lower blood pressure

Although some people claim that dandelion may lower blood pressure, studies are limited.

In Western medicine, diuretic medications are used to eliminate excess fluid, which may help lower blood pressure.

An older human study found that dandelion is an effective diuretic. However, this study was short and included only 17 people.

Dandelion also contains potassium, a mineral associated with lower blood pressure in people who previously had high blood pressure. Thus, this plant may indirectly affect blood pressure because of its potassium content.

Notably, this effect is not unique to dandelion — it applies to all potassium-rich foods consumed as part of a healthy diet.

SUMMARY Dandelion may lower blood pressure because of its diuretic effects and potassium content. However, very little research is available.

7. May promote liver health

Some animal studies suggest that dandelion extract may protect against liver damage and disease.

One animal study found that dandelion root extract helped prevent liver damage in rats with liver failure.

Other animal studies have found that dandelion extract may reduce excess fat stored in the liver and protect against oxidative stress.

However, human research is needed.

SUMMARY Animal studies indicate that dandelion may protect against liver damage, but more research in humans is needed.

8. May aid weight loss

Some research indicates that dandelion and its compounds may support weight management, although the evidence is inconclusive.

Some researchers suggest that dandelion’s ability to improve carbohydrate metabolism and reduce fat absorption may lead to weight loss. However, this theory has yet to be scientifically proven.

A study in mice also suggests that dandelion extract may support weight management by reducing fat absorption.

Another study in mice found that chlorogenic acid, a compound found in dandelions, reduced body weight, decreased fat accumulation, and altered the levels of specific proteins involved in regulating body weight.

However, more high-quality research involving humans is needed.

SUMMARY Some animal studies note that compounds in dandelion may support weight management, but human studies have not evaluated this effect.

9. May support healthy digestion and treat constipation

Dandelion is commonly used in traditional medicine to treat constipation and improve digestive health.

In an older animal study, the frequency of stomach contractions and gastric emptying increased significantly in rats treated with dandelion extract.

Dandelion root is also a rich source of the prebiotic fiber inulin, which has been shown to reduce constipation and promote the movement of food through the digestive tract.

Furthermore, because it contains more than 3 grams of fiber per cooked cup (105 grams), dandelion greens may increase fiber intake. Fiber supports regular bowel movements and protects against various digestive conditions, including hemorrhoids and diverticulitis.

SUMMARY Dandelion is rich in fiber and prebiotic compounds such as inulin — both of which may support gut function, among other digestive benefits.

10. May strengthen immune system health

Some research suggests that dandelion may have antimicrobial and antiviral properties that could support the body's ability to resist infections.

Several test-tube studies have shown that dandelion extract significantly reduces viruses' ability to replicate.

Research also indicates that some active compounds in dandelion may protect against harmful bacteria and fungi.

Ultimately, more research in humans is needed.

SUMMARY Although human research is lacking, some test-tube studies suggest that dandelion has antiviral, antifungal, and antibacterial properties.

11. May be a beneficial skin care treatment

Animal and test-tube research has shown that dandelion extract may protect against sun-induced skin damage, aging, and acne.

In one study, fermented dandelion extract soup prevented skin damage when applied immediately before or after exposure to UVB radiation, the type of radiation received from sunlight.

An older test-tube study found that dandelion root extract increased the formation of new skin cells, which may help improve the appearance of skin as it ages.

In addition, older research shows that dandelion extract may reduce skin inflammation and irritation while increasing hydration and collagen production. This may be useful in preventing and treating certain types of acne.

However, recent research on dandelion’s effects on skin health is lacking, and studies are limited to test tubes and animals.

SUMMARY Animal and test-tube studies suggest that dandelion may protect against skin damage caused by sun exposure, aging, and acne. More human research is needed.

12. May support healthy bones

Very little research has been conducted on dandelion’s effects on bone health, although some nutrients contribute to maintaining strong, healthy bones.

Dandelion is a good source of calcium and vitamin K, which play crucial roles in bone health.

A small study linked increased consumption of vitamin K-rich leafy greens with lower blood levels of osteocalcin, a protein found in bones. This suggests that eating more leafy greens, such as dandelion, may help prevent bone loss.

Inulin, a fiber found in dandelion root, may also support healthy bones by improving digestion and gut health.

In addition, some research suggests that antioxidants in dandelion and other greens play a key role in bone health and protect against bone loss by reducing oxidative stress.

SUMMARY Research on dandelion’s effects on bone health is lacking, although some compounds in the plant may support the maintenance of strong bones.

Dosage and supplement forms

People often consume dandelion leaves, stems, and flowers in their natural form. You can eat them cooked or raw. The root is usually dried, ground, and used as a tea or coffee substitute.

Dandelion is also available as a supplement in capsule, extract, or tincture form.

There are currently no clear dosage guidelines because very little human research has been conducted. However, the available data suggest the following dosages for different forms of dandelion:

• Fresh leaves: 4–10 grams per day

SUMMARY There are no clear dosage guidelines for dandelion supplements because research is limited. Different forms of dandelion may require different dosages.

Potential risks and side effects

Dandelion plants have low toxicity and are probably safe for most people, especially when consumed as food.

However, keep in mind that research is still limited, and dandelion is not entirely risk-free.

This plant may cause allergic reactions, especially in people who are allergic to related plants such as ragweed. Contact dermatitis may also occur in people with sensitive skin.

An older review suggests that dandelion may interact with medications, including certain antibiotics, blood thinners, and blood sugar-lowering medications. If you take prescription medications, consider consulting a healthcare professional before taking dandelion.

SUMMARY Dandelion is probably safe for most people. However, it may cause allergic reactions and interact with certain medications.
