WHAT IT DOES
That weed in your yard is actually a well-studied digestive and liver support herb with natural diuretic properties.

DOES IT WORK?
Dandelion root and leaf have centuries of traditional use and some modern research to back it up. The root supports liver function and bile production. The leaf is a gentle natural diuretic (hence the French name 'pissenlit'). Not dramatic, but genuinely helpful for digestion, mild water retention, and liver support.
