potent

This term carries a sense of concentrated strength, often implying a hidden or latent energy that is ready to be unleashed. It is frequently used in medical or chemical contexts to describe substances that work quickly and intensely, or in political contexts to describe a person's ability to sway others. While powerful is a general term, potent suggests a specific kind of efficacy or potency, such as the sharp smell of a strong perfume or the persuasive force of a well-crafted argument. It often implies that a small amount of the subject is sufficient to produce a significant result.
