Latin/Botanical	Lagenaria siceraria (Molina) Standl.

Key Phytochemical Constituents

• Cucurbitacins (cucurbitacin B, D, E)
• Flavone C-glycosides and beta-glycosides
• Triterpenoids and sterols
• Pectin and dietary soluble fibers
• Beta-carotene and ascorbic acid
• Saponins

How does it work?

• Cardioprotective activity through reduction of serum lipids and modulation of cardiac enzyme markers
• Hepatoprotective mechanism via antioxidant enzyme restoration and reduction of lipid peroxidation
• Anti-inflammatory activity through inhibition of COX and LOX pathways by flavonoids
• Hypoglycemic effect via alpha-glucosidase inhibition and enhanced insulin sensitivity

Which traditional uses are supported by research?

These summaries come from the source notes, which do not name the studies behind them.

• Cardiotonic and heart-protective (Hridya): traditionally used to support the heart. Preclinical studies have reported reductions in cholesterol and triglycerides.
• Cooling and diuretic (Sheetala, Mutrala): traditionally used as a cooling and diuretic herb. Pharmacological studies have reported diuretic activity.
• Hepatoprotective (Yakrit-shodhana): traditionally used to protect the liver. Animal studies have reported protection against drug-induced liver toxicity.
• Obesity: traditionally used for weight reduction. Several studies have reported antihyperlipidemic and anti-obesity effects.

  This review summarises animal studies reporting antihyperlipidemic and cardioprotective effects, with reduced serum cholesterol and triglycerides.

Only studies that could be traced to a published paper are listed here. An absence here means we could not identify the source, not that no work exists.

Recent safety updates

• Bitter variety of bottle gourd (containing high cucurbitacin levels) is toxic and has caused fatalities; only the non-bitter edible variety should be used medicinally
• Fresh juice consumption in excess can cause gastrointestinal irritation, nausea, and vomiting; moderate consumption is generally safe
• Bitter bottle gourd juice has been linked to cases of hematemesis and shock; taste-testing before consumption is strongly advised
