sergey [27]
There is not enough evidence to support that <span>vitamin C aid in sore throat. But there is no harm too.

In the medical field, every treatment should be supported by evidence. This practice called evidence-based medicine.

Theory or argument about why it should work is not enough, you need to do a research to find the truth.</span>
