Black tea extract is derived from the leaves of the Camellia sinensis plant, which is the same plant used to produce black tea. This extract is rich in antioxidants, particularly polyphenols, which are believed to provide various health benefits. It is often used in dietary supplements and skincare products due to its potential to support heart health and improve skin appearance. The extraction process involves steeping the leaves in water or using solvents to concentrate the beneficial compounds. Black tea extract can be found in various forms, including powders, capsules, and liquid extracts, making it easy to incorporate into daily routines.
