Introduction: The study is focused to determine the properties (antimicrobial, antioxidant, anticancer and phytochemical) of the Camellia sinensis. In this study the extract of Camellia sinensis performed to assess the antimicrobial potential against skin associated microorganisms. Antioxidant activity performed in the plant Camellia sinensis play a protective major role in different types of cancer, heart diseases and stroke. Objective: To identify the rich components present in green tea leaves aqueous extract by phytochemical methods and then it is useful as drug for various human effects and problems. Methods: The tea leaves extract was subjected to phytochemical tests, Gas chromatography-mass spectroscopy (GC-MS), Fourier transform infrared spectroscopy (FTIR) analysis and antimicrobial test. Phytochemical analysis of Green tea leaves (Camellia sinensis) was performed and the result showed that the presence of phenolic compounds (alkaloids, flavonoids, steroids, triterpenoids and tannins). Antimicrobial property was performed with two different gram-positive and gram-negative bacteria. Result: Laboratory studies shows that herbs like Camellia sinensis (green tea leaves) can be effectively used in curing bleeding, mental health, regulate body temperature, healing wounds, and to aid digestion. It also shows positive impact on types of cancer such as breast cancer, bladder cancer, ovarian cancer, skin cancer and so on. Conclusion: Camellia sinensis are rich in flavonoids, caffeine and catechins. The tea leaves extract possesses an excellent antimicrobial, antioxidant property which can be used as an alternative drug of choice due to its lower side-effects to human.
