A medicinal preparation or remedy claimed to counteract weariness, fatigue, or exhaustion.
From Greek a- (against) + kopē (weariness), with the noun suffix -on. This is a Greek-derived pharmaceutical term for anti-fatigue medicine.
Medieval apothecaries sold mystery 'acopons' and 'acopic' remedies that promised to banish tiredness—most were just sugar and herbs, but occasionally they'd actually contain stimulants, making people feel temporarily energized through caffeine or mild toxins.
