Botany
Bakaig is a smooth, climbing shrub reaching a length of 10 meters or more. Branches are armed with short, stout, hard, hooked prickles. Leaves are bipinnate, 20 to 30 centimeters long, and the rachis armed with recurved spines beneath. Pinnae are 6 to 8, and rather distant. Leaflets are 4 to 6 on each pinna, leathery, shining, ovate to elliptic-ovate, 2 to 5 centimeters long, and pointed at the tip. Flowers are yellow, borne in terminal and ample panicles, and about 1 centimeter in diameter. Pod is 4 to 5 centimeters long, 2.5 to 3 centimeters wide, beaked, hard, and indehiscent, and contains a single seed.

Also used as uterine stimulant and for cleansing the uterus. (9)

Studies
Anthelmintic:
Anthelmintic activity of Chenopodium album (L.) and Caesalpinia crista (L.) against trichostrongylid nematodes of sheep: Study showed both C. crista and C. ablum possess anthelmintic activity in vitro and in vivo, supporting its traditional use in Pakistan. (2)
Anti-Amyloidogenic / Alzheimer's Disease:
Abeta (amyloid beta) is a major etiological factor in Alzheimer's disease. Study showed C. crista aqueous extract could inhibit the Abeta(42) aggregation from monomers and oligomers and able to disintegrate the preformed fibrils. (3)
Nootropic / Memory Enhancer / Seeds:
Study evaluated the potential of dried seed kernels of C. crista extract as a learning and memory enhancer. Results suggest CC can be beneficial in improving cognition in disorders like dementia and other neurodegenerative disorders. (4)
Antioxidant:
A 70% methanol extract of C. crista leaves showed antioxidant and ROS scavenging, attributed to phenolic and flavonoid compounds. (6)
Antioxidant / Anti-Inflammatory / Leaves: Study evaluated the antioxidant and anti-inflammatory potential of C. asiatica and C. crista leaf extracts. Both exhibited antioxidant properties and inhibited 5-lipoxygenase (anti-inflammatory) in a dose dependent manner, with C. crista showing better activities than C. asiatica, attributed to the higher gallic acid and ferulic acid content. (7)
Hepatoprotective / Iron-Overload Liver Toxicity: Study evaluated the ameliorating effect of C. crista extract on iron-overload-induced liver injury in mice. Treatment showed attenuation of percentage increase in liver iron and serum ferritin levels. CCME also showed a dose-dependent inhibition of lipid peroxidation, protein oxidation and liver fibrosis. The hepatoprotective effect against the iron overload was attributed to its potent antioxidant and iron-chelating property. (8)
Antidiabetic / Seeds: Study evaluated the antidiabetic activity of ethanolic and aqueous seed extracts of Caesalpinia crista in STZ-induced diabetic 2-day old pups model. Results showed antidiabetic effects, with the aqueous extract showing more significant effect than the ethanolic extract. Histopath studies showed regeneration of ß-cells of the pancreas. (10)
Anticancer / Root Bark: Study evaluated the possible anticancer activity of an alcoholic root bark of Caesalpinia crista against Ehrlich Ascites Carcinoma (EAC) Tumor model. Results showed increased survival time and life span, together with significant reduction of solid tumor mass. (11)
Analgesic / Antioxidant / Anti-Inflammatory / Seeds: Study of an ethanolic seed extract of C. crista showed potent antioxidant activity by DPPH assay, significant anti-inflammatory activity by Carrageenan induced paw edema with diclofenac as standard, and potent analgesic activity by writhing reflexes and tail withdrawal latency in mice. (12)
Antipyretic / Seeds: Study evaluated the antipyretic activity of ethanolic and aqueous extracts of seeds using Brewer's yeast induced pyrexia in various experimental animal models. Results showed antipyretic action attributed to the inhibition of prostaglandin synthesis. The ethanolic extract showed more significant activity than the aqueous extract. (13)
Antimicrobial / Seeds: Study showed seed extracts of Caesalpinia crista to have antimicrobial activity against seven of eight selected strains of bacteria and fungi, showing maximum inhibitory effect on P. aeruginosa and F. oxysporum. (14)
Antimalarial / Seeds: Study evaluated 44 cassane- and norcassane-type diterpenes isolated from C. crista of Mayanmar and Indonesia for antimalarial activity against Plasmodium falcifarum clone in vitro. Most of the tested diterpenes displayed antimalarial activity, with norcaesalpinin E showing the most potent activity with an IC50 of 0.090 µM, more potent than the drug chloroquine. (16)
Seed Oil / Potential: Study of shade dried oil yielded total 19.66% saturated fatty acids and 80.33% unsaturated fatty acids. Physiochemical analysis revealed a non-drying oil. Results suggest a potential for use in preparation of liquid soap, hair shampoos, and value added products. (17)
Hepatoprotective Against Iron Load-Induced Toxicity: Study evaluated the ameliorating effect of C. crista extract on iron overload-induced liver injury. Results showed a dose-dependent inhibition of lipid peroxidation, protein oxidation, and liver fibrosis. Study confirmed the hepatoprotective effect likely related to its potent antioxidant and iron-chelating property. (19)
Antiviral Against Against Poultry Viruses: Various extracts of lathakaranja showed complete inhibition of paramyxovirus while showing highly significant inhibitory activity on orthomyxovirus. Study concludes the medicinal plant C. crista might be useful against economically important viral pathogens of poultry birds. (20)
Anthelmintic / Seeds: Study evaluated crude seed extracts of Caesalpinia crista for anthelmintic activity against Pheretima posthuma and Ascardia galli. Results showed all extracts significantly demonstrated paralysis and death of worms at higher concentration 15% w/v compared to standard drug piperazine citrate. (21)
Antibacterial / Seeds: A methanolic extract yielded two novel compounds, 2-hydroxytrideca-3,6-dienyl-pentanoate and octacosa-12,15-diene along with known compounds. The isolated compounds, extract and fractions showed significant in vitro antibacterial activity against S. aureus and MRSA. (see constituents above) (22)
