Black tea

Black tea is derived from the fermented leaves of the Camellia sinensis plant, which are dried and processed. Unlike green and oolong teas, which are made from the same plant but from different processing methods, black tea undergoes a fermentation process.

With a caffeine content ranging from 2% to 4%, black tea is known to enhance cognitive function and alertness. Additionally, it contains antioxidants and other compounds that may contribute to the protection of heart health and blood vessels. Notably, its properties differ from those of green tea, despite both being derived from the Camellia sinensis plant.

Black tea is commonly utilized to boost mental acuity and address issues such as headaches, low and high blood pressure, Parkinson’s disease prevention, depression, dementia, stroke prevention, and various other conditions. However, scientific evidence supporting these purported benefits remains inconclusive.
