Studies
· Hepatoprotective / Carbon Tetrachloride:
Study evaluating the effects of Cassia occidentalis on carbon tetrachloride-induced liver damage in rats concludes that the antioxidant content of Cassia occidentalis might play a major role in hepatoprotection and controlling tissue damage caused by reactive oxygen species. (1)
Protective effect of Cassia occidentalis L. on cyclophosphamide-induced suppression of humoral immunity in mice:
C. occidentalis possesses antimutagenic activity against cyclophosphamide-induced mutagenicity in mice. The study suggests that through the modulation of hepatic drug metabolizing enzymes, C. occidentalis may be influencing the hematotoxic and immunotoxic responses of cyclophosphamide. (2)
Antimicrobial:
Antimicrobial screening of Cassia occidentalis L. in vivo and in vitro: Ethanol extracts of C. occidentalis and metabolite-rich fractions (anthraquinones, sennosides and flavonoids) of leaves, pods and flowers were tested against human pathogenic bacteria and fungi. The anthraquinones were found to be more active against E. coli and S. aureus.
Antimicrobial: In a study of various extracts, methanol and aqueous extracts showed significant antimicrobial activity against seven human bacterial pathogens and two fungal strains. The most susceptible organism was P. aeruginosa followed by P. mirabilis and C. albicans.
Antihepatotoxic Activity of Cassia occidentalis:
An ethanol extract of leaves of Cassia occidentalis was evaluated for antihepatotoxic activity against carbon tetrachloride and thioacetamide as hepatotoxins.
Antimutagenic:
Study of the aqueous extract of CO on its mutagenic potential against chromosomal aberrations showed antimutagenic activity by modulating the xenobiotic activation and detoxification mechanisms. (5)
Antimalarial: (1) The antimalarial activity of C occidentalis has been confirmed. The plant showed more than 60% inhibition of parasite growth in vitro. (2) In a study of the extracts of 3 medicinal plants for antimalarial activity, M morindoides and P niruri showed 74 and 72% suppression, while C occidentalis was slightly less active at 60% chemosuppression of Plasmodium berghei in mice.
Antibacterial: In an Argentinian study of 132 water extracts from 54 plant families, C occidentalis was one of those that showed greater antibacterial activity against Salmonella typhi. (14)
Antidiabetic: Ethanolic extract of C. occidentalis exhibited significant antidiabetic activity in normal and alloxan-induced diabetic rats, with improvement in parameters of body weight, lipid profiles and histopathologic changes showing regeneration of pancreatic B-cells.
(7) A methanolic extract of leaves tested against alloxan-induced diabetic mice showed significant reduction of blood glucose in diabetic mice. (35) Study evaluated a methanol fraction of C. occidentalis leaves against streptozotocin-induced diabetic rats. Results showed significant and dose-dependent effect on biochemical parameters and hepatic marker enzymes (p<0.05) with histopathologic pancreatic protective effect. (44)
Antimicrobial / Phytochemicals: Preliminary screening showed anthraquinones, carbohydrates, glycosides, cardiac glycosides, sterols, flavanoids, saponins, phytosterols, gums and mucilages. Of the extracts studied, the methanol and aqueous extracts showed significant antimicrobial activity against tested organisms, esp: P aeruginosa, P mirabilis and Candida albicans. (8)
Toxicological Reproductive Study: In the rain forests and other tropical regions of South America, CO is considered a potent abortifacient. Results of this study showed no statistically significant difference between the control and treated groups in many of the observed parameters. However, there was the presence of dead fetuses registered in both doses of 250 and 500 mg/kg of CO. Further studies are needed and its use is not recommended in pregnancy. (9)
Poisoning / Hepatomyoencephalopathy: Recurrent outbreaks of an acute encepalopathy illness to in India, earlier attributed to a viral encephalitis, were probably caused by the consumption of C. occidentalis beans with its phytotoxins. causing a multisystem disease - a hepatomyoencephalopathy syndrome. Public education has the potential to prevent future outbreaks. (10)
Wound healing: Study showed the topical application of a methanol extract of C. occidentalis and a pure compound Chrysophanol, an anthraquinone derivative, promoted wound healing activity in excision, incision and dead space models in rats.
(11)

Anti-Trypanosomal Activity / Leaves: Study evaluated an ethanolic extract of leaves of Senna occidentalis for anti-trypanosomal activity in mice infected with T. brucei. Results showed the extracts possess trypanocidal properties and a potential source of a new trypanocidal agent. (28) Study investigated the in vitro and in vivo antitrypanosomal effects of an ethanol extract of Senna occidentalis leaves. Treatment of infected animals with extract significantly (p<0.05) prevented the trypanosome-induced increase in biochemical indices, and significant (p<0.05) ameliorated associated hepatomegaly and splenomegaly. (48)
Histological Female Reproductive Effects / Antifertility: Study evaluated the histological effects of an aqueous extract on female reproductive organ in wistar rats.

(51)
· Antimalarial / Leaves: Study evaluated the claimed antimalarial properties of 58 crude extracts from 15 plants used in traditional medicine against malaria and fever in the Southern African regions using air-dried extracts of powdered plant parts (roots, leaves, seeds, or bark) for schizontocidal activity against 3D7 Plasmodium falcifarum strain. An ethanol extract of C. occidentalis leaves showed high in-vitro antimalarial activity against P. falcifarum chloroquine-sensitive strain (IC50<3 µg/mL). An n-hexane extract showed an IC50 of 19.3 ± 2.0 µg/mL. (52)
· Antimalarial / Roots: Study evaluated the in-vivo and in-vtro antiplasmodial activities of various extracts of Senna occidentalis roots against P. falcifarum and P. berghei. The most effective chemotherapeutic agent was the methanolic extract. The extracts prolonged the mean survival time in all the experimental groups relative to the non-treatment group )p<0.0001). Results suggest SO roots possess bioactive anti-plasmodial compound. (56)
· Anthelmintic / Toxicity Study / Leaves: Study evaluated the in-vitro anthelmintic activity of a methanolic leaf extract of C. occidentalis against Heterakis gallinarum and Ascaridia galli worms. Acute toxicity evaluation showed the extract to be safe according to OECD guidelines, with no mortality and toxicity in mice even at 25,000 mg/kg. There was a concentration-dependent relationship with worm mortality with a mean worm mortality significantly higher for A. galli than for piperazine. EC50 was 11.78 mg/ml for A. galli and 17.78 mg/ml for H. gallinarum. (53)
· Antitussive / Roots: Study evaluated a methanolic extract of C. occidentalis roots for antitussive activity in rats by sulfur dioxide-induced cough reflex method. A dose extract of 200 and 400 mg/kg showed significant antitussive activity comparable to codeine phosphate. (54)
· Antiasthmatic / Antihistaminic / Mast Cell Stabilizing / Leaves: Study evaluated the antiasthmatic activity of aqueous extract of leaves of C. occidentalis on in-vitro (histamine-induced contraction in isolated goat tracheal chain) and in-vivo (milk-induced eosinophilia, mast cell degranulation and capillary permeability in mice) animal models. Results showed antihistaminic, mast cell stabilizing, and decreasing capillary permeability effects which suggest a potential role in the treatment of asthma. (55)
· Genotoxicity Evaluation / Leaves: Study evaluated the genotoxic potential of C. occidentalis leaf extract by in-vivo assays system in rats using OECD guidelines. Results showed the CO-A002 did not produce adverse effect and is safe at a dose of 400 mg/kg p.o. (57)
· Myostimulant Effect / Leaves: Study evaluated an aqueous extract of dried leaves for effect on isolated rabbit duodenum. Results showed a myostimulant effect with increase in rhythm and amplitude of isolat4ed intestine muscle. The effect was suppressed which suggests the presence of muscarinic cholinergic compounds in the aqueous extract. (58)

Toxicity
General info: Poisonous when taken in considerable amounts by domesticated animals, known to cause deaths in cows, horses and goats. The seeds contain emodin, mucilage, proteins, tannic acid, fatty acids and essential oils. There are many anthraquinone derivatives and alkaloids in CO, and no single principle toxin has been identified. Toxicity seems to occur with seasonality, when the beans become palatable with the taste of raw edible beans.
Animals: Plant causes poisoning in different plant species. all parts are toxic, but with differing levels of toxicity. Most poisoning in animals come from pods and beans. In cattle, it is reported to cause severe muscle degeneration, liver degeneration and death. The toxic effects can be rapidly fatal.
Vet clinical signs: Toxicity manifestations include lethargy, recumbency, jerky respiration, tremors, diarrhea, ataxia, hyperpnea, incoordination. Death may occur within 24 hours.
Risk of Poisoning in Children: The beans may be an object of use in the games, playing house, play-cooking and accidental ingestions. Pica, an abnormal craving for food as a manifestation of disease or iron deficiency, can be a risk for poisoning in children. Case-fatality rate in acute severe poisoning is 75-80 percent in children.
Poisoning / Hepatomyoencephalopathy: In India, cases of acute encepalopathy were subsequently attributed to consumption of C. occidentalis beans causing a multisystem disease - a hepatomyoencephalopathy syndrome. Public education has the potential to prevent future outbreaks.   (10)
Toxic Cardiomyopathy in Poisoned Rabbits: Ground endosperm of seeds given to rabbits caused a fatal cardiomyopathy with mitochondrial degeneration, lipid accumulation, myofibrillar degeneration, myocytolysis and minor reparative changes. (22)
Clinical & Pathological Features of Toxicity: The toxic effects in large animals, rodents and chickens are on skeletal muscle, liver, kidney and heart. Pathological findings are necrosis of skeletal muscle fibers and hepatic centrilobular necrosis; renal tubular necrosis is less frequent. Toxicity is attributed to various anthraquinones, derivatives and alkaloids. The clinical spectrum and histopath are similar in animals and children.w
· Non-Toxicity in Acute and Subacute Testing / Stem and Leaf: A preclinical safety evaluation of hydroalcoholic extract of C. occidentalis stem and leaf in in male and female Wistar rats did not show acute and subacute toxicity, suggesting safety for use by humans.
(
40)
· Anthraquinones / Toxicity: Study identified the key moieties in CO seeds and their cytotoxicity in rat primary hepatocytes and HepG2 cells. GC-MS analysis of different fractions of methanol extracts of seeds yielded five anthraquinones (AQs), viz. physcion, emodin, rhein, aloe-emodin, and chrysophanol. In cytotoxicity analysis of the AQs in rat primary hepatocytes and HepG2 cells, rhein showed to be the most toxic moiety. Study indicate AQ aglycones are responsible for producing toxicity, which may be associated with symptoms of hepatomyoencephalopathy in CO poisoning cases.
(
46)
· Hepatic Toxicity: Study of fresh leaves in albino rats showed hypoproteinaemic effects, with increase in ALT, AST, and ALP, suggesting the leaves may be slightly toxic as a concoction for liver ailments.
