The yellow rosettes in the lawn that many people call trash now sit in clinical trial registries. Dandelion leaves and roots are under investigation for effects on liver enzymes and blood glucose control, as researchers test what folk medicine claimed long before modern pharmacology.
Dandelion is rich in phytochemicals such as chicoric acid, taraxasterol and inulin, a soluble dietary fiber. These compounds interact with pathways involved in oxidative stress, hepatic detoxification and insulin signaling. Studies have reported changes in alanine aminotransferase and aspartate aminotransferase, markers of hepatocellular integrity, as well as modest effects on fasting plasma glucose and insulin sensitivity in controlled settings.
The plant’s success as a weed is part of the story. A robust secondary metabolite profile helps it survive herbivores, microbes and environmental stress, and those same molecules are now being mapped to targets like reactive oxygen species and inflammatory cytokines. While most homeowners still reach for herbicide, pharmacognosy labs are cataloguing dandelion extracts, distinguishing between whole‑plant infusions and standardized preparations, and testing dose, safety and mechanism in human volunteers.
