One thousand years ago, pills were wrapped with seeds of Plantago psyllium. This practice was introduced by Arab doctors and lasted till the 19th century when sugar coating was introduced.
B. SEEDS IN INDUSTRY
Guar and locust tree gum have been used for centuries. In ancient Egypt, locust tree gum was used as an adhesive for mummy bandages. Now they are used as thickeners in the food, paper and tobacco industries. These two types of gum thickeners come from the seeds of two different plant species from the legume family. Guar gum is made from the seeds of the Cyamopsis tetragonolobus while the locust tree gum is made from seeds of Ceratonia siliqua.
C. SEEDS AS FOOD
Chocolate originates from Mexico where the Mayas cultivated Theobroma cacao for food and currency. Cocoa, the main ingredient in chocolate, is obtained from seeds located in the pulp of the big elliptic fruits. To produce cocoa the seeds are removed from the fruit, fermented, dried and ground.
