Introduction To The Himalayan Yew
The Himalayan yew, or Taxus wallichiana as it is scientifically known, is a medium-sized coniferous evergreen yew tree, that can grow up to 10 meters and can be found throughout the Himalayas, which includes Nepal, and certain parts of Southeast Asia. It has the ability to grow in a variety of locations, such as mountain forests and areas with mild temperatures, as well as warmer regions that range between 900 - 3,700 meters in elevation. Its appearance can vary based on where it grows, sometimes resembling a low-branched tree or a large spreading bush. Its shoots are green at first, becoming brown after three-four years.Â
Sporting dark green needle-like leaves and reddish-brown bark, each tree either bears male or female flowers. The female trees produce small, fleshy, bright red or orange-red berry-like structures known as arils which encase a single seed—the tree's reproductive structure. These cones have diameters ranging from 1-2 centimeters. Esteemed for its timber, the wood of the Himalayan yew is hard, dense, and durable with an appealing reddish-brown hue. Â
In Nepal, locals refer to it as Lothsalla, and is mainly found in Central to East Nepal Unfortunately, this incredible tree is now at risk of vanishing. Particularly in India and Nepal, the harvesting of its leaves and bark has led to a staggering decline of up to 90% in some areas. As a result, the IUCN has designated the species as endangered.
The Himalayan Yew is believed to be poisonous. But there are contradictory opinions that only European Yews are poisonous. In any case, we should use any product of The Himalayan Yew only under proper guidance.
