Now I'm in a snit. the fifth group contained "cevadillas". No can find definition. A couple mentions of it being in some kind of eyedrops, so perhaps a botanical medication.

PS. After a long hard search, I finally found that "cevadilla" is an alternate spelling of "Sabadilla".
SABADILLA: A broad-spectrum, short residual (2 days in sunlight) botanical insecticide derived from a South American lily. It can be very toxic to humans in purified form.

As a side rant, I laughed heartily at a homeopathic site, which displayed a long "scientific" homeopathic study of treatment of allergy with "extract of honey bee, cevadilla, etc." with; no definitions whatsoever as to what "extract of honeybee" actuall consisted of, nor any details about it. That's homeopathic science at its best! (end rant)
