Kalonji, scientifically known as Nigella sativa, is a widely used medicinal herb and spice. In Ayurveda, it is known as Upakunchika or Sthulajiraka (Big Cumin). While often confused with Black Cumin (Carum carvi / Krishna Jiraka), Kalonji consists of small, black, angular seeds that are valued for their digestive, carminative, and uterine-cleansing properties. It is considered a powerful Krimighna (killer of worms/parasites) and Dipana (digestive stimulant).
Kalonji comes from a small herb (45–60 cm high) cultivated mostly in Punjab, Himachal Pradesh, and Bihar. The medicinal part is the seed, which is flattened, oblong, angular, and rugged (tubercular). The seeds are black, funnel-shaped, and possess a slightly aromatic odor with a bitter taste. In Ayurveda, it is highly valued for normalizing Vata and Kapha doshas and is traditionally used to improve intellect (Medhya) and eyesight (Caksusya), alongside its primary role in digestion.
According to the Ayurvedic Pharmacopoeia of India:
Kalonji is indicated in Ayurveda for the following conditions:
The recommended dosage according to the Ayurvedic Pharmacopoeia of India is:
Kalonji is generally considered safe when consumed in culinary amounts or recommended therapeutic doses. However, due to its Ushna (hot) nature, it increases body heat.
