The raw material contains: coumarin compounds (0,9% coumarin, up to 0,2% melilotine, free coumaric acid, dicoumarol), allantoin, flavonoids, tannins. Glycosides of hydroxycinnamic acids contained in the fresh herb are transformed into coumarin during drying.
The melilot herb reduces blood coagulability, improving the blood flow through venous and capillary vessels, and has anti-inflammatory activity.
Internally, it is only used as an ingredient of herbal combinations. It must be taken with caution, as due to its anticoagulant activity (coumarine) it may cause internal bleeding.
Externally, used for softening the skin and wound healing. Melilot products for internal use should be used un small doses and for short periods.
It is best to follow your doctor's advice. This applies especially to people with hemorrhagic diathesis and people taking anticoagulant medication (e.g. aspirin, polopirin). Should be taken with caution by people with liver and kidney failure.
