The Himalayas are home to a diversity of medicinal resources. Plants from the forests have been used for millennia to treat conditions ranging from simple coughs to snake bites. Different parts of the plants - root, flower, stem, leaves, and bark - are used as remedies for different ailments. For example, a bark extract from an abies pindrow tree is used to treat coughs and bronchitis. Leaf and stem paste from an arachne cordifolia is used for wounds and as an antidote for snake bites. The bark of a callicarpa arborea is used for skin ailments. Nearly a fifth of the gymnosperms, angiosperms and pteridophytes in the Himalayas are found to have medicinal properties, and more are likely to be discovered.
