The Dual Nature of Poisonous Plants

Some plants are known for their dual properties of being both poisonous and medicinal. For example, the yew tree, revered for its longevity and history, contains toxic compounds in every part of the plant but is also a source of the anti-cancer drug paclitaxel, which originally was harvested unsustainably from its bark. This highlights how certain toxic plants can provide significant health benefits when appropriately processed and extracted, though sustainable practices remain critical to prevent depletion of these valuable natural resources. Additionally, the Madagascar periwinkle initially was observed for its role in traditional medicine, leading to successful anti-cancer treatments when its toxic compounds were identified and utilized.
