Arctander writes very extensively about propenyl guaethol and some extracts follow, he describes it as: “intensely sweet, but in the dry state rather medicinal -phenolic odor, often described as “drug store odor”. the sweet odor is more perceptible at high dilution, while the phenolic odor seems to vanish at such low concentrations.”
