; this gives cassia bark a much thicker and rougher texture than that of true cinnamon.

Most of the spice sold as cinnamon in the United States and Canada (where Ceylon cinnamon is still generally unknown) is actually cassia. In some cases, cassia is labeled "Chinese cinnamon" to distinguish it from the more expensive Ceylon cinnamon (C. verum), which is the preferred form of the spice used in Mexico, Europe and Oceania.
"Indonesian cinnamon", also referred to as C. burmannii, is also commonly sold in the United States where it is labeled only as cinnamon.

Indonesian cassia has the lowest oil content of the three types of cassia and, consequently, commands the lowest price.

 recipes, where Ceylon cinnamon is less suitable. Cassia is sometimes added to Ceylon cinnamon, but is a much thicker, coarser product. Cassia is sold as pieces of bark (as pictured below) or as neat quills or sticks. Cassia sticks can be distinguished from Ceylon cinnamon sticks in the following manner: cinnamon sticks have many thin layers and can easily be made into powder using a coffee or spice grinder, whereas cassia sticks are extremely hard, are usually made up of one thick layer, and can break an electric spice or coffee grinder if one attempts to grind them without first breaking them into very small pieces.

Cassia buds, although rare, are also occasionally used as a spice. They resemble cloves in appearance and have a mild, flowery cinnamon flavor. Cassia buds are primarily used in old-fashioned pickling recipes, marinades, and teas.

Health benefits and risks

In 2006, a study reported no statistically significant additional benefit when cinnamon cassia powder was given to type 2 diabetes patients who were already being treated with metformin. A systematic review of research indicates that cinnamon may reduce fasting blood sugar, but does not have an effect on hemoglobin A1C, a biological marker of long-term diabetes.

Chemist Richard Anderson says that his research has shown that most, if not all, of cinnamon's antidiabetic effect is in its water-soluble fraction, not the oil (the ground cinnamon spice itself should be ingested for benefit, not the oil or a water extraction). In fact, some cinnamon oil-entrained compounds could prove toxic in high concentrations. Cassia's effects on enhancing insulin sensitivity appear to be mediated by type-A
