excitant

Such action may be inhibitory or excitant, according to the views of the one or the other author, without affecting the main question as above stated.

The excitant is a dilute solution of sulphuric acid.

The Ainu are gentle and mild by nature, but, like all ignorant people, they are extremely superstitious, and superstition is a powerful excitant.

These have in their medicine-chests the most powerful excitants, which might give a shock even to a man half-dead: they can deafen you, intoxicate you, make you shudder, or bring tears to your eyes.

Some nerve excitants known to you act slowly, others quickly; why not others still instantaneously?
