Tonight on Science for Sleep, we explore the quiet and fascinating world of poisonous plants.

From foxglove and milkweed to rhubarb, black walnut, cassava, belladonna, and yew trees, this calm science documentary looks at how plants evolved chemical defenses, why beauty does not always mean safety, how animals respond to plant toxins, and how some powerful plant compounds helped shape medicine, folklore, farming, and ecology.

Settle in for a slow, relaxing journey through gardens, forests, wetlands, deserts, and ancient plant knowledge, where every leaf, root, seed, and flower tells a deeper story of survival.
