ABSTRACT
Purpose: Among the Hausas of Northern Nigeria; it is claimed by local (traditional) healers that the infusion of C. occidentalis leaves is used as a cure for hepatitis. This study was designed to evaluate the possible negative effects of the aqueous extract of this herb on serum total proteins; albumin; bilirubin; alanine amino transferase (ALT); aspartate amino transferase (AST) and alkaline phosphatase (ALP); as part of a larger study undertaken by these authors to ascertain the hepatoprotective potential of the plant extract. Methods: Fresh leaves of C. occidentalis were extracted with water and screened for phytochemical components. The extract was used for the treatment of 18 albino rats. Serum from these animals was used for the determination of the test parameters. Results: The extract showed hypoproteinaemic effect. ALT; AST and ALP levels were significantly elevated (P 0.05). Conclusion: Hypoproteinaemic effects; and increase in ALT; AST and ALP are indications that the crude extract of C. occidentalis leaves may be slightly toxic as a concoction for liver ailments
