Michael,
Your words are WONDERFUL! Thank you for sharing. I will, with your permission,
print it out for our residents (and faculty).
I give extra credit to our residents who I catch telling patients about the
vegetable dye IF they give me the name of the vegetable from which it is made.

vegetables are organic
sodium fluorescein is carbon, sodium, hydrogen, and oxygen combined
synthetically
synthesize means to form a material by combining parts or elements
carbon is a widely distributed element that forms organic compounds in
combination with hydrogen, oxygen
"we are carbon based life forms, Captain" - remember your Spock !
organic means noting or pertaining to a class of chemical compounds that
formerly comprised only those existing in or derived from plants or animals,
but that now includes all other compounds of carbon., that is characteristic
of, pertaining to, or derived from living organisms: organic remains found in
rocks.
The carbon in plants come from the carbon found in carbon dioxide (CO2). As
plants undergo photosynthesis they draw in water through their roots and carbon
dioxide from the air through specialized structures called stomates. So the
inorganic carbon in carbon dioxide becomes organic carbon making up the oils,
carbohydrates and proteins found in plants.
carbon is the compressed dinosaurs and the vegetation they ate 60 million years
ago, compressed over time by the overlying dust from space that continues to
bombard earth daily ( that where the dust comes from even when we clean so well)
so fluorescein is made from carbon. which, technically, is vegetables, just
very old ones no one can eat easily.
it is synthetic.... it is organic... it is vegetable
but it ain't rutabagas !

July is here and so are the new residents! During a lecture/discussion about
fluorescein sodium yesterday, we discussed how fluorescein sodium is a
synthetic dye and NOT a vegetable dye. One of them had already read/heard it
was a vegetable dye. He asked if there were ever ingredients in the dye that
were vegetable based and if that is why this rumor exists. Does anybody know
why some people refer to it as a vegetable dye?
Thanks!
