קְצִיעָה
qəṣīʿā
Hebrew
“An aromatic bark so close to cinnamon that the ancient world often confused them — yet distinct enough to earn its own name in the Bible, its own price in Roman markets, and its own place in the pharmacopoeia of three civilizations.”
Cassia enters English from Latin cassia, from Greek κασία (kasía), ultimately from Hebrew קְצִיעָה (qəṣīʿā), meaning 'to scrape off' or 'to strip bark' — a name that describes the harvesting method rather than the plant itself. The tree whose bark was stripped is Cinnamomum cassia (also called Chinese cinnamon), a close relative of the 'true cinnamon' (Cinnamomum verum) native to Sri Lanka. The two species produce similar aromatic barks, but cassia is thicker, darker, more pungent, and contains significantly more coumarin, a compound with a characteristic sweet, hay-like scent. The ancient world knew both products and struggled to distinguish them consistently — Herodotus, Theophrastus, and Pliny all discuss the difference between cassia and cinnamomum without achieving complete clarity. The confusion was partly deliberate: Arab traders who controlled the supply had every incentive to keep the botanical facts obscure, as uncertainty about origins justified higher prices and discouraged competitors from seeking out the source directly.
Cassia appears in the Hebrew Bible in Exodus 30:24 as one of the ingredients in the sacred anointing oil that Moses was commanded to prepare — a blend of myrrh, cinnamon, calamus, and cassia mixed with olive oil. The Psalms mention cassia as a perfume for royal garments: 'All your robes are fragrant with myrrh and aloes and cassia' (Psalm 45:8). These references establish cassia as a luxury aromatic known to the ancient Israelites, almost certainly acquired through trade with Arabian merchants who sourced it from Southeast and East Asian networks. Chinese sources describe cassia cultivation from at least the third century BCE, and the spice was a significant commodity in the trade between southern China and the maritime Southeast Asian world. The overland route through Central Asia — what would later be called the Silk Road — also carried cassia westward, alongside silk, jade, and other Chinese exports.
The Romans distinguished between cassia and cinnamon in their markets, with cinnamon generally commanding a higher price. Pliny listed multiple grades of cassia, noting that the finest came from the territories beyond India — a vague geographical designation that probably encompassed southern China and mainland Southeast Asia. Roman demand for cassia and cinnamon was enormous: both spices were used in cooking, perfumery, medicine, and funerary rites. The emperor Nero was reported to have burned a year's supply of cinnamon at the funeral of his wife Poppaea — a gesture of extravagance that scandalized even Rome's jaded senatorial class. The distinction between cassia and cinnamon has never been entirely resolved in popular usage. In the United States today, what is sold as 'cinnamon' in most grocery stores is actually cassia — the thicker, cheaper, more pungent bark from Cinnamomum cassia, usually sourced from China, Indonesia, or Vietnam. True Sri Lankan cinnamon, with its delicate, layered quills and subtler flavor, is labeled 'Ceylon cinnamon' and commands a premium price.
The health implications of this naming confusion have become a subject of genuine medical concern. Cassia contains significant levels of coumarin, which can cause liver damage in susceptible individuals when consumed in large quantities over time. European food safety authorities have established maximum recommended daily intakes for coumarin, and German Christmas cookie recipes — which call for large quantities of what Germans call Zimt (cinnamon, but usually cassia) — have been flagged as potential sources of excessive coumarin exposure. True cinnamon contains only trace amounts of coumarin. The ancient confusion between the two barks, which seemed like a mere taxonomic quibble for centuries, has thus acquired practical health significance. Cassia remains the world's dominant 'cinnamon' by volume — China, Indonesia, and Vietnam produce vastly more cassia than Sri Lanka produces true cinnamon. The bark that the Hebrew Bible prescribed for sacred oil and Roman perfumers blended into their finest preparations is, in all likelihood, the same bark sitting in most kitchen spice racks today, still misidentified after three thousand years.

Cassia is the most consumed spice that almost nobody knows by name. When an American adds 'cinnamon' to apple pie, pumpkin latte, or oatmeal, the substance in the jar is almost certainly Cinnamomum cassia, not Cinnamomum verum. The ancient confusion between the two barks has never been resolved at the consumer level; it has simply been institutionalized. Grocery stores label cassia as cinnamon, recipes call for cinnamon and receive cassia, and the average cook neither knows nor particularly cares about the distinction. The Hebrew word qəṣīʿā — the name that distinguished this specific bark in the most sacred recipe of the Torah — has been swallowed by its more famous cousin's name.
Yet the distinction matters, and not only for reasons of flavor or health. The cassia-cinnamon confusion is a case study in how trade routes create and sustain misinformation. Arab merchants in antiquity deliberately obscured the origins and identities of their spices to maintain commercial advantage. That deliberate obscurity fossilized into genuine confusion, which became standardized nomenclature, which became grocery-store labeling. Three thousand years of accumulated imprecision now means that when you reach for the cinnamon, you are reaching for cassia — the bark that was always there, always cheaper, always more abundant, but never quite allowed to bear its own name in the popular imagination.
