The process of “tanning” an animal hide derives its name from the plant tannins originally used.
Answer: True.
Since Neolithic times, tannins derived from the bark of trees were used to prevent the spoilage of animal skins. The word “tanning” is derived from the Latin tannum, “oak bark.” Plant tannins have antimicrobial properties that help to preserve the hide and astringent properties that draw out moisture, turning the hide into durable leather.
