Primary

Shortens days of upper-respiratory discomfort

Alkylamides and polysaccharides can modulate immune-cell activity, so days of sore throat and congestion at the start of a cold are shorter in some trials. People who want to shorten the course as soon as the throat itches more often see change in days of discomfort when they use it continuously at the outset.

Primary

Lessens early throat and nasal congestion

The same immune modulation lands on local mucosa; severity of sneezing, congestion, and a scraped throat often falls together. People whose nose is blocked on the first day of a season change more often see a difference in easier breathing and more comfortable swallowing after several continuous days.

Common cold

Alkylamides and polysaccharides can modulate immune-cell activity, so days of sore throat and congestion at the start of a cold are shorter in some trials.
