[Herbalist] Got a question

[Carper, Rachel]

I have a friend who is looking for the name of a medicinal herb
conccotion that basically cured everything because it contained
everthing. She remembers it had essential mint oil and some juices, and
somebody brought a sample to the Hearth and Home Collegium in Meridies.

Does anybody know what this is?

And does anybody know if people drank fruit juices in period?
