Abstract

Snake bite envenoming is a global occupational hazard and most of the people of the world trust in traditional medicine for snake poisoning. The present review elaborates scientifically un-investigated/ ignored medicinal plants of Pakistan showing chemical constituents of natural origin with possible mechanisms showing anti-venom activity. This review enlists 35 plants with their families, distribution in Pakistan, parts used traditionally for snake bite treatment and various active principles present in them. Compositae is the most excessive family, with 3 species, followed by Amaranthaceae, Apocynaceae, Asclepiadaceae, Caesalpinaceae, Labiatae, Pinaceae, Polygonaceae and Verbinaceae having 2 species of medicinal plants. While, one plant species belongs to each, Aizoaceae, Araceae, Boraginaceae, Chenopodiaceae, Cucurbitaceae, Euphorbiaceae, Flacourtiaceae, Gentianaceae, Malvaceae, Menispermaceae, Mimosaceae, Oxalidaceae, Papilionaceae, Plantaginaceae, Salvadoraceae and Solanaceae. As an antidote to snake poisoning, the traditional use of leaves (35%) is higher than roots (25%), whole plant (21%), flower (7%), wood (5%), fruit (5%) and milky juice (2%). Among life forms of plants, herbs (55%) are more excessively used as snake bite remedy than shrubs (31%) and trees (14%). This article may help the researchers to bring novelty in the field of natural products for the treatment of snake bite. However, chemical and pharmacological studies are necessary to confirm the anti-venom claims about these medicinal plants of Pakistan.
