• Antiplasmodial constituents of Cajanus cajan: Study shows compounds from roots and leaves of CC showed moderately high in vitro activity against Plasmodium falcifarum strain.
• Hypocholesterolemic Effect: Study on the stilbenes containing extract-fraction of CC showed a hypocholesterolemic effect possibly through enhancement of hepatic LDL-receptor and cholesterol 7-alpha-hydroxylase expression levels and bile acid synthesis.
• Evaluation of traditional medicine: effects of Cajanus cajan L. and of Cassia fistula L. on carbohydrate metabolism in mice: Contradicting its traditional use for diabetes, CC did not have a hypo effect on sugar, aand at higher doses produced a hyperglycemic effect.
• Antimicrobial: Antimicrobial effect of leaf extracts of pigeon pea (Cajanus cajan (L.) millsp.) on some human pathogens : Study shows the plants extract to be inhibitory to some bacterial pathogens.
• Antimicrobial / Antifungal: Nigerian study on the antimicrobial effects of the ethanol and aqueous extracts of locally available plants, including C cajan, showerd inhibition against S aureus, P aeruginosa, E coli and C albicans. The extracts of C cajam produced wider zones of inhibition against C albicans.
• Hyperglycemic Effect: Study of the aqueous extract of C cajan leaves showed a hyperglycemic effect, suggesting a usefulness incontrolling hypoglycemia that may be due to excess of insulin or other hypoglycemic drugs.
• Hepatoprotective: Study of the methanol-aqueous fraction of C cajan leaf extract showed it could prevent the chronically treated alcohol induced rat liver damage and presents a promise as a non-toxic herb for therapeutic use in alcohol-induced liver dysfunction.
