Tea catechins, such as (-)-epigallocatechin-3-O-gallate (EGCG), have been shown to effectively enhance immune activity and prevent cancer, although the underlying mechanism is unclear. Green tea catechins are instead converted to catechin metabolites in the intestine. Here, we show that these green

BACKGROUND Based on published studies, the biological properties of green tea catechins are antiviral, antioxidative, anticarcinogenic, antiangiogenic, and immunostimulatory. The United States Food and Drug Administration has approved a topical ointment formulation of sinecatechins, derived from

Many health benefits have been associated with tea consumption. In an effort to elucidate the source of these health benefits, numerous phytochemicals have been extracted from tea infusions, some of which have demonstrated promise as clinical therapeutics for cancer therapy. Considering the

This review evaluates the antiviral, antioxidant, and immunostimulatory properties of green tea catechins. Two randomized trials evaluating the activity and efficacy of green tea catechins in the management of external genital warts are presented, and the reported side effects associated with this

BACKGROUND Black tea (Camellia sinensis) has been used as a daily beverage for time immemorial. Immunomodulatory effects of tea are recognized as it stimulates the proliferation of cultured human peripheral blood mononuclear cells. Anti-inflammatory effects of tea have also been depicted in the

Botanical products, including and especially green tea leaves, have a wide range of both reputed and demonstrated health benefits and have been used medicinally for thousands of years. This paper focuses on green tea catechins, principally reviewing their known biologic properties and potential

A polysaccharide was purified from a hot water extract of green tea leaves by measuring the immunostimulatory activity in silkworm larvae. Nuclear magnetic resonance and chemical analysis of acid hydrolysates revealed that the purified substance possessed a backbone containing polygalacturonic acids

Over eleven hundred publications reporting anticancer activities of polyphenols have appeared in the peer-reviewed literature. In addition, a search of the PubMed database using "polyphenols - cancer - review" as keywords produced over 320 hits for review articles (July 2009). Polyphenol anticancer

BACKGROUND Green tea catechins possess a wide range of pharmacological properties, including antiviral, anti-infective, and immunostimulatory properties. They also have demonstrated inhibitory effects on a variety of enzymatic and metabolic pathways involved in cancer development. Catechins have

BACKGROUND Benign external genital and perianal warts (condylomata acuminata) are disfiguring, displeasing skin tumours caused by human papillomavirus that may vitally burden affected patients and their partners. Current treatment options are still unsatisfactory due to low efficacy, high recurrence

Background External genital warts (EGWs, condylomata acuminata) are a common, highly contagious disease caused by human papillomavirus (HPV), predominantly HPV 6 and HPV 11. Green tea catechins have been identified for their immunostimulatory, antiproliferative and antitumour properties. Two phase

Immunosuppressive drugs have been developed from natural products such as soil and fungi, which are also the sources of some commonly used herbal products. However, the effect of herbal products on immune response has not been investigated. Because these products can affect the host immune system
