The traditional processing approach applied to produce green tea preserves the Camellia sinensis plant's distinctive color palate and extracts its fresh, savory flavors. Green tea is rich in bioactive compounds that benefit health. It contains the amino acid L-theanine which may improve brain function. It also offers powerful antioxidants that multiple studies conclude could lower the risk of various types of cancer. The bioactive compounds in green tea may also reduce the risk of both Alzheimer's and Parkinson's, the two most common neurodegenerative disorders.
