Safety Overview
1.Arjun — Essential Profile
Terminalia arjuna, commonly known as Arjun, is a majestic deciduous tree belonging to the Combretaceae family, widely revered for its distinctive botanical attributes and extensive medicinal value. Native to the Indian subcontinent, this species thrives in diverse ecological niches, particularly along riverbanks, in ravines, and within dry deciduous forests, often indicating the presence of water. It can be found at altitudes up to 1,200 meters across sub-Himalayan regions, including Uttar Pradesh, Punjab, Deccan, South Bihar, Orissa, West Bengal, and Madhya Pradesh.
The Arjun tree typically reaches a height of 20-30 meters, characterized by a broad, horizontally spreading crown and gracefully drooping branches that form a unique silhouette. Its most striking feature is its remarkably smooth, grey or pinkish-white bark, which exfoliates in large, thin, irregular flakes, revealing a fresh, soft, reddish layer beneath. This bark is the primary part harvested for its profound therapeutic properties.
The foliage of Terminalia arjuna consists of simple, coriaceous leaves, typically oblong or elliptic, measuring about 10-15 cm in length and 4-7 cm in width. The leaf margins can be entire or finely toothed, supported by a short petiole, with a pale to dark green upper surface and a lighter pale brown underside.
From April to July, the tree produces small, inconspicuous yellowish-white flowers, which are sessile and bisexual, arranged in short axillary spikes or grouped into terminal panicles. Following this, from September to November, the tree develops its distinctive fruits—woody, obovate-oblong drupes 2.5-5 cm long, characterized by a smooth skin and five prominent, fibrous wings that aid in their dispersal.
