My guess is it's a cipher of some kind. Probably to do with spagyria (a form of alchemy involving plant medicines). Reason being that people involved in that didn't often want to share their secrets back in the day, and so you get a wide variety of novel symbol sets for use by small groups or even a single individual. It was not uncommon to use more than one language in the same text, and sometimes even in the same sentence. But that's just a guess.
