What are the medicinal properties of Allium ursinum?

Allium ursinum helps with digestive issues, such as bloating and flatulence, and has antibacterial properties that aid in wound healing. Its extracts are also used to reduce inflammation and relieve stress. Additionally, it may help regulate blood sugar levels.

The active constituents of Allium ursinum responsible for its medicinal properties are sulfur compounds, specifically allicin, which has potent antimicrobial and anti-inflammatory effects. Other bioactive compounds present include saponins, flavonoids, and phenolic acids. These compounds contribute to its therapeutic benefits.
