I recently read news about cloves and came across:

The irony of the situation is that the instructions for the drug, which is called "Reaferon EU Lipinth", does not contain a mention of encephalitis at all. “We are now finishing clinical trials. After all, the drug was originally created to treat hepatitis, then it turned out that it helps very well with flu and chlamydia. Finally, in the last two years, infectiologists have prescribed it in the treatment of encephalitis. By this season we do not have time to officially complete clinical trials, but by the end of the year, I think we will get official approval from the Ministry of Health.

Only our strict doctors first come up with a medicine and then understand what it is for.
