Dandelion root is generally considered safe when consumed in food amounts or as a dietary supplement, and it has a long history of traditional use across Europe, Asia, and North America. Toxicological evaluations have not identified inherent toxicity in Taraxacum officinale when used appropriately, and adverse effects are typically mild and uncommon.

The most frequently reported side effects associated with dandelion root involve gastrointestinal discomfort, including bloating, diarrhea, or stomach upset. These effects are thought to be related to its bitter compounds and natural diuretic properties, which may increase bile flow and urine output. Such reactions are usually dose-dependent and resolve when intake is reduced or discontinued. National Institutes of Health – Office of Dietary Supplements
Allergic reactions are possible, particularly in individuals with sensitivities to plants in the Asteraceae family, which includes ragweed, marigolds, and daisies. Contact dermatitis and oral irritation have been documented in rare cases, emphasizing the importance of caution for individuals with known plant allergies.

Dandelion root may interact with certain medications, especially diuretics, lithium, and drugs metabolized through liver enzymes. Its potential to influence fluid balance and bile secretion means individuals taking prescription medications should consult healthcare professionals before regular use. These interactions are theoretical but biologically plausible based on known pharmacological pathways. U.S. National Library of Medicine – MedlinePlus
Special populations require additional caution. Individuals with gallbladder disease, bile duct obstruction, kidney disorders, or hormone-sensitive conditions are advised to avoid unsupervised use due to possible complications. Safety data for pregnancy and breastfeeding remains insufficient, leading medical authorities to recommend avoidance in these groups. European Medicines Agency (EMA)
Overall, dandelion root is best understood as a low-risk botanical when used responsibly and within dietary or traditional frameworks. Ongoing research continues to refine safety guidance, reinforcing the importance of evidence-based use rather than assumptions based on natural origin alone. World Health Organization (WHO)
