Native to tropical areas, cassia seed is harvested from the cassia or jue ming zi plant. It is also used as “cinnamon” although it is not true cinnamon from the cinnamon tree bark. Cassia seed is sometimes used in weight loss products for its laxative effects.
Contraindications: Should not be used by individuals who are taking blood
Studies: There are studies that suggest some use of cassia for eyesight and lowering cholesterol. I didn’t find anything on weight loss. It may work due to its laxative effect, but then, that’s not a good way to lose weight.
Quantity needed: N/A
