More about salutary
Salutary ultimately comes from Latin salūs (inflectional stem salūt-) “health, welfare, safety.” In its sense of “promoting or conducive to some beneficial purpose; wholesome,” salutary entered English in the late 1400s. Salutary, in its sense of “favorable to or promoting health; healthful,” emerged in the mid-1600s. A synonym for salutary (“healthful”) is salubrious, which is also rooted in Latin salūs. Salūs could also mean “greeting,” as in greeting someone with “best wishes (for their well-being).” This meaning of salūs gave rise to the verb salūtāre “to greet, hail,” source of the English noun and verb salute.
