 The chemical components of tea leaves include:

  • Polyphenols (catechins and flavonoides):
    • Tea has about eight to 10 times the polyphenols found in fruits and vegetables, according to long-time tea researcher John Weisburger, PhD, senior researcher at the Institute for Cancer Prevention in Valhalla, N.Y.
    • Although all tea contains beneficial antioxidants, high-quality green and white teas have them in greater concentrations than black tea, due to the oxidation process that the leaves go through.
    • Tea flavonoids have anti-oxidant properties, anti-inflammatory, anti-allergic and anti microbial effects.
    • Catechins, are anti-oxidants which help prevent the effects of stress and support healthy metabolism. As a consequence, they can lower blood lipids and blood pressure, prevent arteriosclerosis, drop blood viscosity and prevent blood clot formation.
    • Epigallocatechin-3-gallate (EGCG), a major polyphenol found in green tea, is a widely studied chemopreventive agent with potential anti-cancer activity. The anti-carcinogenic mechanism includes both cellular immune function and the inhibition of tumor growth (http://www.gaiaresearch.co.za/greentea.html).
    • Intake of tea catechin, together with regular exercise helps to reduce diet-induced obesity. This effect might be attributed to the activation of whole-body energy metabolism.
    • Tea polyphenols lower the serum glucose by inhibiting the activity of the starch digesting enzyme, amylase. Tea inhibits both salivary and intestinal amylase. As a result, the starch is broken down more slowly and the sudden rise in serum glucose is minimized.
  • Alkaloids (caffeine, theobromine, theophylline, etc.)
    • Consumption of tea may have diuretic effects due to the stimulant- caffeine. Tea has more caffeine by weight than coffee.
    • Theophylline in tea, a licensed medicine for the treatment of respiratory diseases such as asthma.
    • Theobromine is also used to dilate blood vessels, as a diuretic, and heart stimulant.
  • Tea also contains theanine, which has psychoactive properties and has been proven to reduce mental and physical stress, improve mood and cognitive abilities, similarly to coffee.
  • Green, black and oolong tea, all having antibacterial, antioxidant, antiseptic and detoxifying properties are very much effective in treating infectious dysentery as well as easing inflammatory bowel disease. This makes tea useful as a traditional home remedy for various digestive problems.
  • Other componants in tea include- Volatile oils, polysaccharides, amino acids, lipids, vitamins (e.g., vitamin C), fluorine, manganese, oxalates, tannins, etc.
