The body absorbs medicine, it doesn't have to be directly applied to the infection for it to work.
Also, things such as cough sweets don't contain medicine, only things such as Mentho-Lyptus. The sweet is swallowed down the esophagus, but the vapours from it are inhaled down the Trachea to sooth the Bronchi (for Bronchitis).

Esophagus
The name of the tube that food goes down when you swallow is called your esophagus.
The muscles in the esophagus move the food down into the stomach.
The function of the esophagus is to move food from the mouth to te stomach. It is muscles that move the swallowed food slowly down and into your stomach
The trachea is a part of the respiratory system while the esophagus forms part of the digestive system. Since they belong to different systems, they perform separate functions. The trachea is larger and carries gasses in and out of the lungs. The esophagus is smaller and carries food from the mouth to the stomach.
the food goes through your esophagus and through your small & large intestines. there after, it breaks down to solids/liquids & all essentials and enters your digestive area
the food is then forced down the esophagus.
The esophagus has a physical break down. The esophagus squeezes the food down into the stomach, making this a physical break down.
It can lacerate (cut) and get lodged in your esophagus and if it manages to work it's way down to your stomach it can do a lot of damage there. If you have swallowed a sharp object go to ER immediately!
The oesophagus is the tube that takes swallowed food from the mouth to the stomach.
the bolus is formed by chemwing food. it is swallowed and muscles in your throat push it down the esophagus past a valve into your stomach. once there the bolus disintegrates and digestion begins.
