For sure, searched cipro and it pulled up Benzyl alcohol lol......
Cipro has a benzene ring and an OH group, so it's practically the same thing if you squint a little.
Seems like the entry on Drugbank for insulin is "insulin human", which explains why it doesn't return an immediate match. The closest match using Levenshtein distance is "inulin" instead.
Thanks for pointing that out :) I'll have to do some tweaking.
