guaifenesin = glycerol guaicacolate 200mg in each tablet (label)
Guaifenesin (INN) or guaiphenesin (former BAN) aka glyceryl guaiacolate (wiki)
??what's the difference between glyceryl and glycerol??
glycerol = a sweet syrupy trihydroxy alcohol
obtained by saponification of fats and oils
glyceryl = a trivalent radical derived from glycerol
by removing the three hydroxyl radicals

OTC PO expectorant, usually in pill or syrup form, many brands
from the guaiac tree aka gum tree


(not sure if these images are the right plant)

generic remedy of Native Americans in 1500's
FDA approved in 1952
mb combined with dextromethorphan (antitussive, most common combo, goal: fewer but more productive coughs), pseudoephedrine/phenylephrine, acetaminophen, poss codeine
