It increases the flow rate in veins (and the lymph system) and decreases capillary permeability but has no anticoagulant properties." \\ | "Extracts are used to treat the symptoms of venous and lymphatic insuffiency and capillary fragility, such as varicose veins, pruritus, cramp in the calf and in acute attacks of haemorrhoids...

| In living plants, coumarin is glycosidically bound as melilotoside, an odorless precursor. On wilting or injuring, o-coumaric acid (o-hydroxy-trans-cinnamic acid) is released from the glucoside; o-trans-coumaric acid is in equilibrium with the cis-coumaric acid, which then spontaneously lactonizes to coumarin. Coumarin is the aroma impact compound of wilted or dried M.officinalis. \\ | In living plants, coumarin is glycosidically bound as melilotoside, an odorless precursor.

| Coumarin alone made up more than 89% of all volatiles collected from M.officinalis. An extract obtained by solid-liquid extraction of dry sweet clover herb could be fractionated to identify minor volatile components. Higher proportions of coumarin derivatives such as 3,4-dihydrocoumarin, dihydrocoumaric acid methyl and ethyl ester could be found. Other minor components are anethol, 4-methoxy benzaldehyde (anisaldehyde), 2-hexadecanone, and cresol eg.; γ-pentadecalactone was regarded as species indicator compound among the 84 components identified from M.officinale volatiles. \\ [Volatile constituents of sweet clover (Melilotus officinalis L.
