In contrast, a recent study in Japan indicated that the consumption of green tea was not associated with either a reduction or an increase in gastric cancer rates [ 31 ] . This raises concern as to the ability of polyphenols derived from green tea to afford protection from mutagenic substances or limit the progression of established cancer.
Several pharmacological properties of plants reputed to be snakebite antidotes include antimyotoxic, antihaemorrhagic, analgesic, and antiedematogenic, blockage of cutaneous and intraperitoneal capillary permeability activity caused by the venom and protection from its lethality [ 38 ] . A more direct anti-venom activity would involve complexation of the compounds with venom constituents thus rendering them unable to act on receptors; or to act by competitive blocking of the receptors [ 11 ] . Phenolic compounds especially complex polyphenols like some tannins can bind with proteins [ 42 ] . Alternatively, the catecholamines released as a result of venom-receptor interaction may be antagonised or metabolised more quickly [ 11 ] .

Recently, both green tea and cat's claw have been reported to reduce the expression of inflammatory genes; responses that are linked to apoptosis and proliferation [ 23 24 25 26 27 ] . Indeed, cat's claw has been described as a potent inhibitor of the transcription factor NF-κB activation, preventing the expression of TNFα and inducible nitric oxide synthase [ 23 24 ] . These immune/inflammatory products are associated with gastritis and epithelial cell death [ 5 6 7 13 ] and hence cat's claw may have utility in limiting gut inflammation [ 23 ] . Indeed, this matches its ethnomedical use in South America where it is used to treat gastritis and other forms of chronic inflammation like arthritis [ 28 ] . Green tea, and its constituent polyphenols, has been associated with reduced expression of inflammatory genes and signal transduction processes leading to cell death [ 21 25 26 27 ] .
Laboratory investigations support the capability of citrus peel or its major constituents, d-limonene, and also the ability of tea extract or its constituents, tea polyphenols to reduce not only the incidence and tumor size of chemically-induced tumors at several sites [ 4 8 9 17 18 20 22 ] but also the growth of various tumor cells in culture [ 11 33 ] . Both d-limonene, representative of citrus peel, and tea polyphenols, representative of black tea, are known to impact antiproliferative effects, including apoptosis, on neoplastic cells [ 4 34 35 36 37 ] . Dietary d-limonene has been shown to be effective in the chemoprevention and chemotherapy of cancer.
