utilis) that produce a dose-related increase in the clotting time of blood induced by carpet viper venom ( Echis carinatus ) would be useful against bites from Bothrops species that cause haemorrhage at the point of injection due to the inhibition of the clotting mechanism [ 40 ] . Antivenom compounds so far isolated from plants include protocatechuic acid, a catechin-gallo-catechin tannin, caffeic acid derivatives (chlorogenic acid, cynarin), coumarins (bergapten), flavonoids (rutin, isoscutellarein, kaempferol, quercetin, hesperidin), ar-turmerone, alkaloids (aristolochic acid), triterpenoids, triterpenes, coumestans (wedelolactone), sterols (sitosterol, stigmasterol, beta-amyrin), triterpenoid glycosides, alkaloids (allantoin) and lignoflavonoids [ 43 40 44 42 ] . Many relevant compounds are widely distributed nitrogen-free, low molecular weight compounds (except aristolochic acid, an untypical non-basic, nitro-derivative) [ 38 ] . The structural similarities of certain plant chemicals found in plants used for snakebites are an isoflavone skeleton, acidic nature and dioxygenated functionality [ 44 ] .

Complications in the bitten limb can include secondary infections by Gram-negative organisms and acute renal failure among others [ 8 ] . There is a bothrojacarin-like 27 kDa protein in Bothrops species venom [ 36 ] . Bothrojacarin forms a non-covalent complex with thrombin, blocking its ability to induce platelet aggregation and fibrinogen clotting [ 8 36 ] . Haemostatic effects in Lachesis muta venom are attributable to an alpha-fibrin(ogen)ase and haemorrhagic metalloproteinases (LHF-1 and LHF-II) which have alpha-fibrin(ogen)ase activity [ 8 ] .
