Green tea (Camellia sinensis) is a famous herbal plant used as a potent
antioxidant since ancient times with abundant health benefits. Numerous studies have
shown the health benefits of green tea for many diseases. The objective of this article is
to know the importance and various uses of green tea and its important constituents in
poultry for safeguarding various health issues. The present review article also focuses
on several beneficial health applications and salient medicinal properties of green tea
that have not been comprehensively reviewed previously. Owing to the bioactive
constituents, including caffeine, amino acids (AA), L-theanine, polyphenols/
flavonoids and carbohydrates, among other potent molecules, green tea has many
pharmacological and physiological characteristics. Moreover, Camellia sinensis
possesses essential biological compounds such as alkaloids, carotenoids, minerals,
amino acids, carbohydrates, lipids, and volatile compounds. Based on scientific
literature evidence, green tea has multifunctional applications in livestock animal
sectors of dairy, goat and poultry industry. Green tea active ingredients have been
shown to possess many health benefits with various mechanisms like antioxidative,
anti-inflammatory, antiarthritic, antistress, hypolipidemic, hypocholesterolemic,
skin/collagen protective, hepatoprotective, antidiabetic, antimicrobial, anti-infective,
anti-parasitic, anti-cancerous, inhibition of tumorigenesis and angiogenesis, and
improving memory and bone health. The findings presented would be useful for
poultry researchers and farmers and would help to propagate the multidimensional
health benefits of green tea.
