Alchemical Abigrams

I was requested to provide ambigrams for a larper who needed bottles labelled with "relaxant", "poison", "smelling salts" and "antidote". The above is the result. The first three are the "regular" ambigrams, and the last is a wrapping ambigram. Written all around the bottle, it reads the same upside down as forwards but the word doesn't have to start where the the upside down one ends.
