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.

• In China, popular
for its dermatologic and cosmetic applications - for facial blemishes;
moisturizing and skin softening use; anti-wrinkle and anti-aging skin
properties; preventing sun damage.
• In Japan, kondol
is a component of most traditional dermatologic formulations because
of its skin regenerative.
• Tincture or liniments made through percolation with propylene glycol
or hydro-alcoholic solution.
• In Korea, used
for diabetes and kidney problems
• In Ayurveda, used
for coughs, epilepsy, asthma, peptic ulcers. It is also the main ingredient in "Kusumanda Lehyam", used as tonic and for various conditions like epilepsy, constipation, hemorrhoids, dyspepsia, syphilis and diabetes.
• In India, used
for treatment of peptic ulcer: Juice is squeezed out of grated gourd,
equal amounts of water is added, taken daily on an empty stomach, with
no food intake for 2 to 3 hours.
• Fruit juice used for insanity, epilepsy.
• 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: (1) Study results were comparable with
the omeprazole treated group. Study suggest BH possess significant antiulcer
and well as antioxidant property. (2) 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
• 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
• 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: 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: 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.
Cultivated for edible fruit.
