Plural of harmin; toxic alkaloid compounds found in certain plants that can affect the nervous system.
From harmine (a β-carboline alkaloid) + plural -s. The compound was first isolated from plants like Peganum harmala in the early 20th century, with the root 'harm' reflecting its pharmacological effects.
Harmins are naturally occurring plant poisons that have been used in shamanic rituals for centuries, and modern neuroscientists study them because they affect serotonin levels in ways that might help understand depression and anxiety.
