Summary
Caesalpinia bonduc, also known as bonduc nut or fever nut, is a medicinal plant used in various traditional systems for treating conditions such as diabetes, inflammation, and fever [PMID:34192600, PMID:37987793].
Background
Caesalpinia bonduc (L.) Roxb., belonging to the Fabaceae family, is a plant with a pantropical distribution commonly found in evergreen and moist deciduous forests [PMID:34192600, PMID:37987793].
Traditional uses
The plant is used in Ayurveda, Siddha, and homeopathy to treat fever, inflammation, diabetes, cardiovascular disorders, cancer, birth control, and tumors [PMID:34192600, PMID:37987793, PMID:19429358]. In India, seeds are used to regulate menstrual disorders in PCOS [PMID:34192600], while in Benin, roots are used for urinary tract infections, pain, diabetes, reproductive disorders, and as an aphrodisiac [PMID:42256646, PMID:33574881]. It has also been used by Siddha healers for psoriasis [PMID:20920562] and traditionally to treat snake bites [PMID:15070178].
Active compounds
The plant contains over 97 phytochemicals [PMID:37987793]. Key compounds include cassane-type diterpenoids (e.g., caesalpinolides, neocaesalpins) [PMID:34184408, PMID:32985266, PMID:24447681, PMID:24990509, PMID:19155029], cassane-type alkaloids (caesalminines C-G) [PMID:38280683], flavonoids [PMID:34400957], phenolics [PMID:32256963], and a water-soluble gluco-arabinan polysaccharide [PMID:23218357]. Seeds also contain a serine proteinase inhibitor (CbTI) [PMID:17400464].
Mechanism of action
In diabetic rat models, polyphenol extracts may attenuate hyperglycemia by upregulating insulin secretion and inhibiting the JNK signaling pathway, affecting genes such as Pdx-1, Ins-1, ngn-3, GLUT-4, and IRS-1 [PMID:32256963]. Ethanolic seed extracts trigger a yeast metacaspase-dependent apoptotic pathway in Candida albicans via mitochondrial dysfunction and enhanced production of calcium and reactive oxygen species (ROS) [PMID:36093184]. Certain compounds have shown inhibitory effects on type-4 phosphodiesterase (PDE4) and nuclear factor-kappa B (NF-κB) expression [PMID:31962203].
Clinical evidence
Evidence DDiabetes Mellitus
Aqueous-methanol seed kernel extract, alone or synergistically with Gymnema sylvestre, improved fasting blood glucose, insulin, HbA1c, and oxidative stress markers (SOD and CAT) in alloxan-induced diabetic rats [PMID:40354793]. Polyphenol extracts restored blood glucose, insulin, and glycosylated hemoglobin in diabetic rats [PMID:32256963].
Evidence DBenign Prostatic Hyperplasia (BPH)
Seed extracts significantly decreased testosterone propionate-induced BPH in male Wistar rats [PMID:35651598].
Evidence DPsoriasis
Hydroalcoholic extract fractions (butanol and water) produced significant orthokeratosis and reduced relative epidermal thickness in mouse tail tests [PMID:20920562].
Evidence DInflammation and Pain
Seed coat extract decreased induced inflammation in Carrageenan and Egg albumin-induced paw edema models in rats and showed antinociceptive activity [PMID:23057003].
Evidence DCandidiasis
Ethanolic extract of seeds demonstrated in-vitro anticandidal activity against Candida albicans [PMID:36093184].
Safety & adverse effects
A 90-day oral toxicity study of ethanolic root extract in rats (up to 500 mg/kg/day) showed no deaths, abnormal clinical signs, or significant changes in body weight and organ weights [PMID:33574881]. However, acute oral administration of leaf and young twig extracts (2000-5000 mg/kg) caused significant alterations in biomarkers and cellular damage to the liver [PMID:24311878]. In sub-acute studies, doses of 400 mg/kg and above of leaf/twig extracts caused significant biomarker changes [PMID:24311878].
Evidence summary
The current evidence is primarily based on in-vitro studies and animal models (Level D), with some systematic reviews of traditional use and phytochemistry (Level A/C). There are no human clinical trials provided in the abstracts.
