Meliloto:12 properties, benefits and ways of use

The melilot, Melilotus officinalis of the Leguminosae family , is an annual or biennial herbaceous plant that grows as a bush and reaches a height of 1.5 m.The local names attributed are: Cavalin in Piedmont, Trifoglio cavallino in Lombardy, Spain salvadega in Veneto, Vetturina grass in Tuscany, Trifoglio melato in Puglia, Vetarina grass in the Marche.

The stems are simple or more often branched with the hollow interior. The leaves are trifoliate (divided into 3 small leaflets) while the flowersgather in clusters composed of 30/70 yellow flowers. The fruit is a black-brown legume, while the seeds are ovoid and greenish-yellow in color.

It grows in Europe and in Western Asia, from the sea to the submontana region of the whole of Italy, in the fields, in uncultivated and sunny places, along the roads.

The drug, that is the part of phytotherapic interest, is represented by the flowering tops.

The flowering tops are harvested between June and August by cutting only the flexible branches, not the hardened ones and when the weather is dry. The plant must be dried very well because moisture can develop a mold that turns coumarins into dicumarol, a toxic substance used as a rat poison and which interferes with coagulation. The sweet clover does not act directly on blood coagulation.

The harvest does not cause damage to the species, but it is important that the plant is not torn up and that some floral clusters are always left intact.

It is considered a forage plant that sometimes has an infesting character.

The tops, gathered in bunches, are dried in the shade and kept in paper or canvas bags.

The main coumarin present is melitoside with vasoprotective activity, an activity similar to escine contained in the horse chestnut.

Contains flavonoids that possess antiseptic and diuretic properties. There are tannins, essential oil, resins and starch.
