Which method involves the application of medications directly to the skin?

Inunctions refer specifically to the method of applying medications directly onto the skin, typically through rubbing or massaging. This technique allows for localized treatment, whereby the medication can penetrate through the skin layers to achieve therapeutic effects. Inunctions are particularly beneficial when targeting specific areas for pain relief or skin conditions, as they facilitate direct delivery of the active ingredients into the affected region.

The other methods listed differ in their application. Dispense involves providing medications in the appropriate form to a patient without necessarily applying it directly to the skin. Potency relates to the strength or effectiveness of a medication, and it does not refer to a method of application. Administer refers to the overall process of giving medications to a patient, which can include various routes such as oral, intravenous, or topical; however, it does not specify the direct application method used in inunctions. Thus, inunctions is the precise choice when highlighting direct application of medications onto the skin.
