A “virtus dormitiva” is ‘A sleep-inducing property or effect of a drug. Also in extended use’ (OED). After an all night shoot and spending a lot of time on the motorway this week, I have no need of a virtus dormitiva since I shall sleep like a log without assistance.
Day #237 of a 365 project, where the daily pic is informed by theĀ OED word of the day.
