A toxic alkaloid compound found in certain tropical plants, particularly in Geissospermum genus trees.
From the genus name 'Geissospermum' (Greek 'geissos' meaning 'rope' or 'wattle' + 'sperma' meaning 'seed') combined with the chemical suffix '-in' for alkaloids.
Nature's chemical factories are incredible—plants in the Amazon evolved this poison as a defense mechanism, and researchers studying it discovered it affects the nervous system in ways that helped develop new medicines.
