What is Kalonji?
If you have cooked Indian or Middle Eastern food, you may already know Kalonji without realising it has a place in Ayurveda: these small black seeds are used for digestion, breathing and immunity. In English it is usually called black seed.
Its botanical name is Nigella sativa Linn. The Sahasra Yoga, a classical collection of formulas whose drug index matches Sanskrit names to Latin plant names, gives its Sanskrit name as Upakunchika.
Our sources record those three uses but not its tastes, potency or doses, so this page sticks to what is known.
