Safety Overview
1.Varun (Caper Tree) — At a Glance
Crataeva nurvala, commonly known as Varun or the Caper Tree, is a distinguished medium-sized, deciduous tree native to the Indian subcontinent and parts of Southeast Asia, typically reaching heights of 10 to 15 meters. Its striking features include palmate leaves, often trifoliate, which can extend up to 25 centimeters in length. Each leaflet is oval to ovoid, displaying a vibrant glossy green that transitions to a rich yellow in autumn.
Varun is particularly notable for its captivating flowers, which emerge in clusters, showcasing a spectrum of colors predominantly from white to pale yellow or creamy hues, each petal measuring approximately 2-3 centimeters and emitting a subtle fragrance. The tree's bark is grayish-brown, characterized by a rough, fissured texture, though it can also appear smooth and brown with distinctive horizontal wrinkles. The fruits are ovoid berries, about 2.5 cm in diameter, resembling small lemons, ripening to a red color and containing multiple seeds embedded in a fleshy yellow pulp.
Varun thrives in warm climates, preferring dry, sandy or loamy soils, and is frequently observed along riverbanks and in open forest environments, particularly abundant in regions like Madhya Pradesh, Kerala, Bengal, and Assam. Taxonomically, it belongs to the Capparaceae family, within the order Brassicales, a classification shared with other plants recognized for their medicinal applications.
