In plain terms, 'Sialogogue Pear Fire Dates' is the type of antibiotic that Aaron was preparing to make.
In ancient times, there was no such thing as antibiotics, and even emperors, prime ministers, generals, and other high officials died in considerable numbers from things like carbuncles.
While herbal medicine has some antibacterial effect, it is clearly not as immediate as antibiotics.
A single Fire Date can't cure all diseases, but combined with Sialogogue Pear, it's almost as good.
By introducing this concoction, Aaron was naturally looking for a better way to masquerade as a mystic.
After all, with his experience traveling through multiple worlds, even without any special power or advantage, he could rise to prominence after lying low for a while.
