"Biogenic amines", which have a stimulating effect, enhancing the function of the central nervous system and improving learning and work efficiency. Caffeine also strengthens myocardial contraction, lowers cholesterol, prevents arteriosclerosis, promotes gastric secretion, and has diuretic effects.

"Tea polyphenols", also known as tannins, enhance the elasticity of capillaries and have antibacterial, anti-inflammatory, and anti-radiation effects.

"Lipopolysaccharides", macromolecular complexes formed by the combination of lipids and polysaccharides, are important components of the cell walls in tea. Lipopolysaccharides in tea have anti-radiation effects and also improve hematopoietic function.

"Proteins and amino acids". Tea protein can reach 15–30%. Tea amino acids benefit growth and development and can regulate fat metabolism.
