"A sprig of parsley can provide much more than a decoration on your plate. Parsley contains two types of unusual components that provide unique health benefits. The first type is volatile oil components - including myristicin, limonene, eugenol, and alpha-thujene. The second type is flavonoids - including apiin, apigenin, crisoeriol, and luteolin." (The World's Healthiest Foods: Parsley)
Sprig is a great word even when not connected to the estimable parsley.
