Key Phytochemical Constituents

  • Embelin (2,5-dihydroxy-3-undecyl-1,4-benzoquinone)
  • Vilangin
  • Christembine (alkaloid)
  • Quercitol
  • Embelinol
  • Embeliaribyl ester
  • Embeliol (1,2,4,5-tetrahydroxy-3-undecanyl benzene)
  • Volatile oils and tannins

How does it work?

  • XIAP inhibition: Embelin is a cell-permeable small-molecule inhibitor of X-linked inhibitor of apoptosis protein, inducing caspase-dependent apoptosis in cancer cells.
  • NF-kB suppression: Blocks TNF-alpha-induced NF-kB activation, suppressing expression of antiapoptotic and metastatic gene products.
  • PI3K/AKT pathway modulation: Inhibits PI3K/AKT signaling leading to reduced cell proliferation and survival in tumor cells.
  • Anthelmintic action: Causes neuromuscular paralysis in helminths through disruption of energy metabolism; tannins and alkaloids precipitate worm proteins.
  • Antioxidant activity: Embelin and vilangin scavenge free radicals and reduce oxidative stress markers including lipid peroxidation.

Which traditional uses are supported by research?

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

  • In vitro and clinical studies have reported anthelmintic activity. The clinical work was in children with Ascaris infections.
  • Laboratory studies have reported Antimicrobial activity against multiple bacterial strains.
  • Studies have reported anti-inflammatory activity involving NF-kB inhibition.
  • Preclinical studies have reported Anticancer potential involving XIAP inhibition and modulation of multiple pathways.
  • Antioxidant activity has been reported in DPPH and other radical scavenging assays.

What do recent studies show?

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

  • Clinical trial in children with ascarids showed no adverse effects during or after treatment with alcoholic (80% success) and aqueous (55% success) extracts.
  • Embelin demonstrated anti-fertility/anti-spermatogenic effects in animal models; contraindicated in pregnancy and in individuals attempting conception.
  • High doses may cause gastrointestinal irritation; recommended to use under practitioner supervision with standardized embelin content.

What is it made of?

Consult a qualified vaidya before acting on anything here. Ayurvedic practice is prescribed to a person, not to a condition: the same dravya is given, withheld or substituted depending on your constitution, your agni, the season and what else you are already taking. A page cannot know any of that. Self-prescribing from a reference is how the wrong preparation, the wrong dose or the wrong anupana gets used.

Educational reference only. Nothing on this page is medical advice, a diagnosis, or a recommendation to take anything. Traditional uses and research findings are reported as published, not as claims about what any product does. If you take prescribed medication, raise any interaction with the prescriber rather than acting on a page. See our editorial standards.
