What does depurative mean?
"Depurative" describes something that purifies, especially something credited with cleansing the blood or ridding the body of impurities. It functions both as an adjective — as in "a depurative herb" — and, less commonly, as a noun meaning a purifying medicine or agent. The word derives from Latin depurare, "to make pure," via forms that also give English "purify" and "pure." Today it survives mostly in specialised contexts: traditional and alternative medicine, where herbs such as nettle, dandelion, and burdock are classed as depuratives; historical medical texts; and translations of European phytotherapy literature, particularly from French and German traditions where the term remains current. It belongs to a formal register and is rarely heard in ordinary conversation, though its meaning is transparent to anyone familiar with words like "purification." Its old-fashioned precision makes it useful when describing historical healing practices without resorting to modern marketing language like "detox."
Having the property of purifying the blood or cleansing the body of impurities.
"Nettle tea was prescribed for its depurative effects at the change of seasons."
Found mainly in herbalist, naturopathic, and historical medical writing.
A medicine or substance that purifies the blood or cleanses the body; a depurant.
"Old pharmacopoeias listed burdock root among the standard depuratives."
Used only for the noun sense referring to purifying medicines or substances.
"Spring cures often combined several gentle depuratives taken over several weeks."
Long before 'detox' became a marketing buzzword, herbalists reached for this Latin-rooted word to describe springtime blood-cleansing cures.

Etymology of depurative
"Depurative" comes from the Latin verb depurare, meaning "to make pure" or "to cleanse," formed from de- (indicating removal) plus purus, "pure." It entered English in the early modern period through late Latin and French medical usage, joining a family of terms built on the same root that includes "purify," "purge," and "depurate." Its closest living cousins appear in Romance-language pharmacology, such as French dépuratif, where it still names blood-cleansing remedies.
