Camellia Sinensis

Camellia sinensis is an evergreen shrub native to East Asia. The leaves and leaf buds of the plant are used to make tea. Different processing methods result in different types of tea, such as green tea, black tea, and oolong tea.

Camellia sinensis is primarily used as a source of brewed tea, valued for its flavor and natural compounds. It is commonly found in tea bags, powdered drink mixes, and as an ingredient in snack and energy bars, often for its perceived health benefits and natural flavor.

Camellia sinensis, particularly in the form of green tea, is a source of antioxidants like catechins. The U.S. Food and Drug Administration (FDA) recognizes green tea extract as Generally Recognized As Safe (GRAS) for certain uses. Regulatory bodies like the European Food Safety Authority (EFSA) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) have evaluated compounds found in tea. While generally considered safe, some studies suggest potential interactions with medications or effects on iron absorption, though evidence is mixed and often depends on the concentration and form consumed.
