I am currently suffering a sore throat. I have purchased some Betadine (gargleable iodine) which I believe and hope actually helps reduce the extent of the infection.
At the risk of derision, I will confess I have also purchased Strepsils (antibacterial throat lozenges) which I believe is mostly a sugar-pill placebo, but it is sweet, distracting from the pain and gives me something to do to feel in control, while I wait for my immune system to get around to dealing with the invaders.
The Strepsils pack admits:
The efficacy of an antibacterial agent in lozenges in reducing the severity or duration of throat infections has not been clinically established.
This suggests "We don't know yet whether this works." I am wondering if the science is actually further progressed than the company is admitting. Should this read "Large-scale experiments have shown throat lozenges are no better than placebo. We know they don't make any noticeable difference." instead?
