Cassia is also a genus of plants in the Family Fabaceae.

Cassia (Cinnamomum aromaticum) is an evergreen tree native to southern China and Indochina, a close relative to the Cinnamon (Cinnamomum zeylanicum) and Camphor (Cinnamomum camphora) trees. As with these species, a spice is made from the bark of Cassia.

Cassia has a greyish bark, and hard elongated leaves that have a decidedly reddish cast when young. Whole branches and small trees is harvested for cassia bark, unlike the small shoots used for cinnamon; this gives the bark a much thicker and rougher texture. The flavour is less delicate than that of cinnamon bark; sometimes cassia is called bastard cinnamon or even sold as cinnamon, as it is not as expensive as true cinnamon.

Up to the 1960s Vietnam was the world's most important producer of cassia. Because of the Vietnam war, production in highland Sumatra, Indonesia was increased, and this remains one of the main cassia exporters today.

Uses

Cassia is used as a flavouring agent, both for sweetmeats and for meat; it is specified in many curry recipes, where cinnamon is less suitable. Cassia is sometimes added to true cinnamon but is a much thicker, coarser product and does not coil into quills as effectively.

History

In classical times, four types of cinnamon were distinguished (and often confused):

• Cassia (Hebrew, qesia), the bark of Cinnamomum iners from Arabia and Ethiopia
• Cinnamon proper (Hebrew qinnamon), the bark of Cinnamomum zeylanicum from Sri Lanka
• Malabathrum or Malobathrum (from Sanskrit tamalapattra), Cinnamomum malabathrum from the North of India
• Serichatum, Cinnamomum cassia from Seres, that is, China.

In Exodus 30, 23, Moses is ordered to use both sweet cinnamon (Kinnamon) and cassia (qesia) together with myrrh, sweet calamus and olive oil to produce a holy oil to anoint the Ark of the Covenant. Psalm 45, 7-8, mentions the garments of the righteous that smell of myrrh, aloe and cassia.

The first Greek reference to kasia is found in a poem by Sappho in the 7th century B.C.

According to Herodot, both cinnamon and cassia grow in Arabia, together with incense, myrrh and ladanum , and are guarded by winged serpents. The phoenix builds its nest from cinnamon and cassia. But Herodot mentions other writers that see the home of Dionysos, e.g. India, as the source of cassia. While Theophrastus gives a rather good account of the plants, but a curious method for harvesting (worms eat away the wood and leave the bark behind), Dioscorides seems to confuse the plant with some kind of water-lily.

Pliny (nat. 12, 86-87) gives a fascinating account of the early spice trade across the Red Sea in "rafts without sails or oars", obviously using the trade-winds, that costs Rome 100 Millions sesterces each year. According to Pliny, a pound (the Roman pound, 327g) of cassia, cinnamon or serichatum cost up to 300 denars, the wage of ten month's labour. Diocletian's Edict on Maximum Prices from 301 AD gives a price of 125 denars for a pound of cassia, while an agricultural labourer earned 25 denars per day.

The Greeks used kásia or malabathron to flavor wine, together with absinth (arthemisia absinthia). Pliny mentions cassia as a flavouring agent for wine as well (Plin. nat. 14, 107f.). Malabathrum leaves (folia) were used in cooking and for distilling an oil used in a caraway-sauce for oysters by the roman gourmet Gaius Gavius Apicius (de re coquinaria I, 29, 30; IX, 7). Malabathrum is among the spices that, according to Apicius, any good kitchen should contain.

Egyptian recipes for kyphi, an aromatic used for burning, include cinnamon and cassia from Hellenistic times onwards. The gifts of Hellenistic rulers to temples sometimes included cassia and cinnamon as well as incense, myrrh and Indian incense (kostos), so we can conclude that the Greeks used it in this way too.

The famous Commagenum, an unguent produced in Commagene in present-day eastern Turkey was made from goose-fat and aromatised with cinnamon oil and spikenard (Nardostrachys jatamansi). Malobrathum from Egypt (Dioscorides I, 63) was based on cattle-fat and contained cinnamon as well; one pound cost 300 denars. The Roman poet Martial (VI, 55) makes fun of Romans who drip unguents, smell of cassia and cinnamon taken from a bird's nest and look down on him who does not smell at all.

Cinnamon, as a warm and dry substance was believed by the ancient doctors to cure, among others, snakebites, freckles, the common cold and kidney troubles.
