Origin:
Mild climatic regions of south and central Europe, north Africa and West Asia. C. scoparius is fairly common in and around Oatacmund (Nilgiris) and is found wild as a garden escape. It grows also in Simla and neighbouring places. An allied species, C.monspessulanus Linn., White Broom, also occurs in the Nilgiri hills.

Action:
Green twigs of the plant, collected before flowering, either fresh or after drying, are used as diuretic and cathartic. Emetic in large doses.
The seeds are also used similarly.
The herb is used chiefly in the form of sulphate in tachycardia and functional palpitation. (The action of the whole plant is stated to be different from that of isolated alkaloids.)
The whole herb has been used to treat tumours.
