Vaividangam, vidanga in Hindi and Sanskrit, is a woody forest climber whose small, wrinkled, dried fruits look like black peppercorns. Ayurveda has used vidanga for intestinal worms for centuries. Over-harvesting from the wild has made it scarce in parts of the Western Ghats and Himalayan foothills, and dried fruit in the market is often mixed with a related species or with pepper.

How to recognise Vaividangam
It is a large climbing shrub with slender, long branches that scramble over trees.
The leaves are elliptic, leathery and pointed, dotted with tiny glands visible against the light.
Tiny greenish-white flowers grow in branched clusters at the shoot tips.
The fruits are small round berries, red when ripe and turning black and wrinkled when dried, about the size of a peppercorn.
Dried fruits often keep a short stalk and a cap of persistent sepals, which pepper lacks.

Modern notes on Vaividangam
The fruit contains embelin, an orange compound that has been studied for activity against worms, microbes and inflammation in laboratories.
Embelin has shown anti-fertility effects in animal studies.
Embelia tsjeriam-cottam is commonly sold as or mixed with vidanga, and black pepper is also used as an adulterant.
Clinical trials in people are few and small.
Vaividangam safety
Avoid vidanga in pregnancy and when trying to conceive, and do not give it to children without a doctor. Worm infections are best treated with tested medicines.
Ecology and sourcing
It grows in moist forests of the Western Ghats, the north-east and the Himalayan foothills, and on into South-east Asia.
Over-collection of fruit and stems has made wild populations scarce, and cultivation is encouraged.
Birds eat the red berries and disperse the seeds.
