Benzonatate is used to relieve coughs due to colds or influenza (flu). It is not to be used for chronic cough that occurs with smoking, asthma, or emphysema or when there is an unusually large amount of mucus or phlegm with the cough. Benzonatate relieves cough by acting directly on the lungs and the breathing passages.

Whitewood is a term cabinetmakers use for a secondary, utility lumber, used for unseen things like toe kick framing, cleats, brackets, webbing, etc. There are a variety of species that get called whitewood, such as pine, poplar, spruce.

These days, I only see spruce in my area.
