Botany
Kondol is a rather coarse, wide-spreading, softly hairy, annual vine with branched tendrils reaching a length of 4 to 8 meters. Leaves are rounded or kidney-shaped, 10 to 25 centimeters diameter, 5- to 7-lobed, heart-shaped at the base. Peduncles are hairy, those of the males being 5 to 15 centimeters long and of the females much shorter. Flowers are large and yellow, with a densely hairy bell-shaped calyx tube. Petals are 5 and spreading, 3 to 5 centimeters long. Fruit is ellipsoid or ovoid, 25 to 40 centimeters long, with few to many fragile hairs, green, and densely covered with a white and waxy bloom. The seeds are many, oblong, and compressed.

Study Findings
• Anti-Ulcer: Extracts of Benincasa hispida prevent development of experimental ulcers: Used in Ayurveda for peptic ulcers, the study showed extracts of BH may be a natural drug with anti-ulcer activity.
• Anti-angiogenic Effect: Study showed the seed extract of Bh decreased bFGF-induced endothelial cell proliferation and tube formation in a dose-dependent manner. It showed no cytotoxicity and showed potent inhibitory effect on bFGF-induced angiogenesis in vivo. Seed extract of BH supports its anti-angiogenic property through inhibition of endothelial cell proliferation.
• Gastroprotective / Anti-Ulcer / Antioxidant: Study results were comparable with the omeprazole treated group. Study suggest BH possess significant antiulcer and well as antioxidant property.
Anti-Ulcer: Study showed decrease in ulcer index in animals treated with fruit extract of Bh. BH has been shown to contain active principles – terpenes, flavonoid C, glycosides and sterols which have antioxidant effects, probably helping inhibit gastric mucosal damage by scavenging free radicals and repressing production of superoxide dismutase.
• Bronchodilator Effect: The ME of BH showed excellent protection against histamine-induced bronchospasm probably through an antihistamine activity (H1 receptor-antagonism).
• Opioid Withdrawal Benefit: Study showed the juice of Bh showed significant activity against symptoms of morphine withdrawal. Results suggest a potential for Bh in preventing the development of morphine addiction and suppression of opioid withdrawal in animals.
• Antinociceptive / Antipyretic: Study results indicate that the ethanolic extract of Benincasa hispida possesses potent antinociceptive and antipyretic effects and pharmacologically justifies its folkloric use for fever and pain conditions.
• Antidiarrheal: Study showed the methanolic extract of fruit of Bh showed significant inhibitory activity against castor oil-induced diarrhea and inhibited PGE2 induced enteric pooling in rats. Results establish its efficacy as an antidiarrheal agent.
• Antioxidant / Alzheimer’s disease: Results revealed chronic treatment of Bh pulp extract markedly decreased lipid peroxidation level, significantly increased superoxide dismutase, CAT and reduced glutathione level in different parts of the brain. Study showed the antioxidant property of Bh may be beneficial in the management of colchicene-induced rat model of Alzheimer’s disease.
• Anorectic / Potential Anti-Obesity Benefit : Study investigated the anorectic effect of the methanol extract of Bh in Swiss albino mice. Results reveal, for a the first time, a possible anorectic activity of Bh, probably through CNS mediation, with no effect on gastric emptying. Further studies are suggested for its antiobesity potential.
• Diabetes : Study investigated the hypoglycemic effects of Bh in STZ-induced diabetic rats. Results showed a possibility of therapeutic or preventive use of wax gourd in diabetes mellitus.
• Renoprotective: Study results showed Benincasa cerifera treatment prevented renal damage induced by ischemia/reperfusion injury in hyperlipidemic rats through decreasing of lipid peroxidation and increased antioxidant enzyme activities.
• Antifungal: Study of a methanol extract of fruit showed no inhibition on bacterial strains tested but showed significant inhibition against Candida albicans.
• Anti-Inflammatory: Study of a methanolic and petroleum ether extracts of fruit of Bh produced dose-dependent and significant inhibition of carrageenan-induced paw edema, histamine induced paw edema and cotton pellet-induced granuloma in a rat model.
• Anti-Urolithiatic: Study evaluated the ameliorating effect of an ethanol extract of seeds in hyperoxaluria and renal cell injury. Results showed an anti-urolithiatic effect with reduction in stone forming constituents in the urine and decreased kidney retention that reduced the solubility product of crystallizing salts.
• Hepatoprotective / Diclofenac Induced Toxicity: Study evaluated the protective role of an aqueous extract of pulps on diclofenac sodium-induced hepatotoxicity model in adult albino rats. Results showed restoration of biochemical changes produce by diclofenac to normal. The significant hepatoprotective effect was through the modulation of antioxidant-mediated mechanism.
• Anthelmintic / Leaves: Study of anthelmintic activity using Pheretima posthuma as test worm showed an extract of fresh leaves with significant activity compared with standard Piperazine citrate group.
• Bioactive Proteins / Cytotoxicity: Study isolated three bioactive proteins from the fruits, seeds and roots. The highest was 0.54% from the root which on cytotoxicity testing showed inhibition of proliferation of HeLa cell and K-562 cells.
• Hispidalin / Cationic Bioactive Peptide / Antimicrobial / Antioxidant / Seeds: Study yielded a bioactive peptide, Hispidalin, from the seeds of Benincasa hispida. The peptide showed broad and potent inhibitory effects against human bacterial and fungal pathogens. It also exhibited DPPH free radical scavenging activity and lipid peroxidation inhibition.
• Anti-Convulsant / Fruit: Study y evaluated a methanol extract of fruit in various convulsive models in mice. Results showed potential anticonvulsant activity with significant inhibition of hind limb extension induced by MES and increased latency of convulsion induced by pentylenetetrazole and strychnine.
• Anxiolytic / Analgesic / Nootropic: Study investigated the neuropharmacological activity of various extracts of B. hispida. Results showed decreased locomotor activity and exploratory behavior. There was significant prolongation of haloperidol induced catalepsy in mice and increased analgesic activity in hot plate method. Results showed potential anxiolytic, analgesic and nootropic activity.
• Hypoglycemic / Analgesic / Nootropic: Study evaluated an aqueous extract of stem of B. hispida for hypoglycemic effect in alloxan-induced diabetic rabbits. The results showed significant dose-dependent reduction in blood glucose levels.
• Memory and Learning Effects / Seeds: Study evaluated the nootropic potential of aqueous and methanol extracts of B. hispida on various behavioral models. Results showed dose-dependent reduction in transfer latency by elevated plus maze, water maze and object recognition task. Results conclude the methanolic extract of B. hispida can be a useful restorative agent in the treatment of dementia.
• Effect on Testosterone Induced Prostatic Hypertrophy: Study evaluated effects of extracts of seed oil on hyperplasia of the prostate induced by subcutaneous administration of testosterone in rats. Results showed inhibition of testosterone-induced hyperplasia in rats, and suggests studies to evaluate its effect in human benign prostatic hyperplasia.
• Hepatoprotective / Nimesulide Induced Toxicity: Study evaluated the protective role of an aqueous extract of pulps on nimesulide-induced hepatotoxicity model in adult albino rats. Results showed significant hepatoprotection through modulation of antioxidant-mediated mechanisms.
• Anthelmintic / Roots: Study evaluated the anthelmintic of various extracts of root. Results showed significant anthelmintic activity against Pheretima posthuma compared to standard Piperazine citrate.
• Anticompulsive Effect: Study of methanolic extract exhibited significant anti-compulsive effect in marble-burying behavior test in mice, which was attributed to enhanced serotonergic function.
• Protective Effect on Colchicene Induced Alzheimer’s Disease: Study of water extract of Benincasa hispida pulp showed a protective effect on colchicene induced experimental rat model of Alzheimer’s disease.
