In one study Trusted Source, people with rheumatoid arthritis protect against Parkinson’s disease.
NCI notes that tea contains trusted source
- Alkaloids include caffeine, theophylline, and theobromine
- amino acids
- Minerals and trace elements
- Volatile organic compounds are what give it its smell and taste.
Black tea’s antioxidant properties are due to its high levels of polyphenols. Polyphenols are chemical substances that protect plants against ultraviolet radiation and disease-causing pathogens.
