What is the primary action of a decongestive treatment?

The primary action of decongestive treatment focuses on drying up mucus in the respiratory passages. Decongestants aim to alleviate congestion by narrowing the blood vessels in the nasal tissues, which leads to reduced swelling and diminished mucus production. This can enhance airflow and ease breathing for individuals experiencing nasal congestion due to allergies, colds, or sinusitis.

While some of the other options, like promoting circulation or relieving inflammation, may have indirect benefits in a broader treatment approach, they are not the direct purpose of decongestive therapies. The main goal remains the management and reduction of mucus buildup, which is particularly relevant in cases where congestion is the primary symptom affecting breathing and comfort.
