Soporificus
/soh-poh-RIF-ih-kus/🏷️ Taxonomy●●● Advanced
Also known as: soporifica, soporificum
A pharmacological epithet indicating the plant has sleep-inducing properties — containing compounds that cause drowsiness or sleep. Related to narcoticus but focusing specifically on the soporific (sleep-inducing) rather than broader narcotic effects. Appears as soporificus (masculine), soporifera (feminine), or soporificum (neuter).
Etymology
From Latin sopor (deep sleep, stupor) + facere (to make), meaning "causing deep sleep."
Example
“Papaver somniferum is again the most celebrated example, and Valeriana officinalis — whose roots are used as a natural sleep aid — illustrates the milder end of the soporific spectrum the epithet describes.”
