Taraxacum officinale, also known as dandelion, is a flowering plant belonging to the Asteraceae family. This widely recognized plant, often considered a weed, features bright yellow flowers and toothed leaves despite its reputation as a garden nuisance. Dandelions have been used over the centuries for culinary and medicinal purposes (Türkmen et al., 2023).
In traditional East Asian practices, dandelion greens are not just a part of culinary dishes but a vital ingredient, particularly in salads. When incorporating dandelion as a food source, it’s important to note that the recommended dosage should not exceed 4 grams to 12 grams daily for the aerial parts of the plant or 1 gram to 3 grams for the root. The roots, leaves, and flowers can be enjoyed either in their raw form or after being cooked (Olas, 2022). In herbal medicine, the versatility of various parts of the dandelion plant, including the leaves, stems, flowers, and roots, further adds to its appeal and potential health benefits.
One of the dandelion’s most noteworthy uses is its diuretic effect, which is well-known globally. Additionally, preliminary research suggests that dandelions may offer protective effects on the pancreas and could possess anti-allergenic properties. Though further study is required, these potential health benefits provide hope for the future of herbal medicine (Fan et al., 2023).
Dandelion is a rich source of various beneficial compounds, including phenolic acids (such as chicoric acid and chlorogenic acid), flavonoids (e.g., luteolin derivatives and quercetin), and terpenes (specifically sesquiterpene lactones). Moreover, dandelion is abundant in essential vitamins (A, C, E, K, and B) and minerals (calcium, sodium, magnesium, iron, copper, silicon, zinc, and manganese). These nutritional components contribute to the potential health benefits associated with dandelion consumption (González-Castejón et al., 2012a) (González-Castejón et al., 2012b).
The dandelion has a wide range of potential health benefits. Its leaves, roots, and flowers are believed to promote liver health and combat inflammation, among other things. Here are 11 health benefits associated with dandelions.
1. May Promote Liver Health
Studies conducted in both animals and test tubes have shown that dandelion may help prevent and treat certain liver diseases, including acute and chronic liver failure (ACLF), nonalcoholic fatty liver disease (NAFLD), and alcohol-related liver damage. However, human studies are needed to confirm whether dandelion can be used medicinally for these purposes. This study suggested that reducing oxidative stress may be a potential mechanism for the protective effect of dandelion in acute and chronic liver failure, and it provided evidence supporting its use for preventive treatment (Pfingstgraf et al., 2021).
2. May Help Manage Inflammation
Research findings have consistently pointed to the potential of dandelion extracts and compounds in mitigating inflammation within the body. These effects have been observed in mice and zebrafish larvae (Li, Luo, et al., 2022). They are attributed to certain chemicals in dandelions (CITATION DELETED). However, further research involving human subjects is required to determine how dandelions can effectively reduce inflammation in the human body.
3. Aiding Digestive Disorders
It is common worldwide to use dandelion as a remedy for constipation and other digestion issues, including dyspepsia, anorexia, stomach disorders, gastritis, and enteritis. A study by (Li, Chen, & Sun-Waterhouse, 2022) suggested that products derived from dandelion may help protect against gastrointestinal disorders. This could be attributed to their anti-inflammatory and antioxidant properties. However, more research is needed as the current knowledge of the potential benefits of dandelion for digestive health is limited.
4. Boosting Immune Health
A review by (Di Napoli & Zucchetti, 2021) observed that dandelions possess both antiviral and antibacterial properties. This means they can combat viruses and bacteria in the body. For instance, a study by (Yang et al., 2020) discovered that dandelions aid in restricting the growth of hepatitis B within cells in laboratory test tubes.
Despite these findings, further research is necessary to fully understand dandelions’ effects on the immune system and determine their impact on immune function.
5. Healthy Gut Bacteria
Dandelion root is abundant in inulin, a soluble fiber commonly found in many plants. Inulin is crucial in supporting the growth and maintenance of beneficial bacteria in the gastrointestinal tract, contributing to overall gut health. This soluble fiber serves as a prebiotic, nourishing the beneficial microbes in the gut and aiding in the balance of the gut microbiota (Ma et al., 2023).
6. Reduce Blood Pressure
Although there have been limited studies on dandelion and its effect on reducing blood pressure, one older human study found dandelion to be an effective diuretic (Clare et al., 2009). This means dandelion may help the body eliminate excess fluid, potentially lowering blood pressure. However, it’s important to note that this study had a small sample group of people, so a more extensive study is needed to confirm these findings. Additionally, dandelion contains potassium, a mineral associated with decreased blood pressure in individuals with previously elevated levels. This suggests that dandelion may have a dual effect on blood pressure through its diuretic properties and potassium content (Olas, 2022).
7. May Reduce Liver and other Cancer Risk
Extensive but limited research findings have suggested the potential of dandelion in inhibiting the growth of specific types of cancer, such as breast cancer, pancreatic cancer, and prostate cancer (Rezaie et al., 2023) (Shi et al., 2022) (Movahhed et al., 2023). Current studies have primarily focused on observing the impact of dandelion on cancer growth in controlled laboratory environments, demonstrating that it may possess properties that slow down the proliferation of specific cancer cells. For instance, a study conducted by (Rehman et al., 2017) explored the effect of dandelion extract on cancer growth in a simulated environment. It concluded that it could potentially reduce the progression of liver cancer.
Despite these promising findings, human trials are imperative to ascertain whether dandelion consumption can offer protective benefits against cancer. Human research is essential to provide concrete evidence regarding the potential role of dandelions in cancer prevention and treatment.
8. Regulating Blood Sugar
Research has suggested that compounds found in dandelion may improve the secretion of insulin, the hormone in charge of regulating blood sugar levels, as well as the absorption of glucose in muscles. These findings indicate that dandelion could have hypoglycemic properties and the ability to reduce insulin resistance and fasting blood glucose levels, which may be beneficial in managing type 2 diabetes (Wirngo et al., 2016). Two bioactive compounds in dandelion, chicoric and chlorogenic acid, have been identified as potential contributors to lowering blood sugar levels (Ferrare et al., 2018). However, it’s important to note that we need additional research to ensure we have any definitive claims.
9. It May Aid Weight Loss
Some studies have proposed that the dandelion’s potential to enhance carbohydrate metabolism and diminish fat absorption could contribute to weight loss. Nevertheless, it’s important to note that scientific research has not substantiated this hypothesis (Gamboa-Gómez et al., 2015). In addition, a study involving mice has suggested that dandelion extract might assist in weight management by lowering fat absorption (Aabideen et al., 2020). Furthermore, another study on mice revealed that chlorogenic acid, a compound in dandelion, reduced body weight, decreased fat accumulation, and modulated levels of specific proteins involved in weight regulation (Zhong et al., 2020). While some evidence suggests that dandelions and their components could aid in weight control, the data still needs to be more conclusive.
10. It May Support Healthy Bones
Dandelion greens are an excellent source of nutrients, particularly calcium (Cormick & Belizán, 2019) and vitamin K (Rodríguez-Olleros Rodríguez & Díaz Curiel, 2019), which are crucial in maintaining bone health. A study has indicated a potentially beneficial association between higher vitamin K-rich leafy green vegetables and reduced blood levels of osteocalcin, a protein essential for bone health (Sim et al., 2020). Additionally, research suggests that the antioxidants in dandelions and other greens contribute significantly to bone health by safeguarding them against bone loss and reducing oxidative stress (Kim et al., 2021).
11. Skin Healthy
Research shows that dandelions may protect the skin from sun damage (Xie et al., 2018). The harmful Ultraviolet (UV) light is known to cause significant damage to the skin. It is a major contributor to skin aging. A study conducted in 2015 on skin cells in a controlled environment found that dandelion extract could mitigate the impact of a specific type of damaging UV light. Shielding the skin from UV damage can help prevent premature aging (Yang & Li, 2015). However, it’s important to note that more extensive studies must be conducted on human subjects to confirm and validate these findings.
Precaution of the use of Dandelion
Dandelion consumption is generally safe for adults when used moderately. However, it may lead to side effects such as diarrhea, upset stomach, or skin irritation (Kania-Dobrowolska & Baraniak, 2022). As a precaution, dandelion supplements should not be used by children or people who are pregnant or breastfeeding. In addition, dandelion has the potential to stimulate the production of stomach acid, leading to heartburn in some individuals. Additionally, it can cause skin irritation. Individuals with kidney issues, gallbladder problems, or a history of gallstones should seek advice from their healthcare provider before consuming dandelion.
Conclusion
Extensive research involving animal and test-tube studies has been undertaken to investigate the potential health benefits of dandelion flowers, leaves, roots, and stems. The findings suggest that dandelions may have a wide-ranging positive impact on various aspects of health. These potential benefits encompass liver health, inflammation management, digestive health support, immune system reinforcement, gut health improvement, blood pressure and blood sugar reduction, and potential efficacy against various types of cancer. Furthermore, dandelions may play a role in weight management and bone health. Additionally, preliminary evidence suggests that dandelions may offer protection against skin damage caused by sun exposure, aging, and acne. However, it is essential to emphasize that further extensive studies with human subjects are crucial to confirm and validate these promising findings.
