Herbal teas have been part of traditional wellness practices for centuries, and one lesser-known yet powerful option is Nigella seed tea. Made from the tiny black seeds of Nigella sativa — often called black seed, black cumin, or kalonji — this tea has been valued in Middle Eastern, South Asian, and Mediterranean traditions for both its flavor and medicinal potential.
Modern science has begun to explore many of the compounds found in Nigella seeds, particularly thymoquinone, which contributes to its antioxidant and anti-inflammatory properties. While research is ongoing, the tea continues to attract interest from health enthusiasts seeking natural ways to support immunity, digestion, and overall wellbeing. This guide explores what Nigella seed tea is, its proven health benefits, possible side effects, preparation methods, and practical consumption advice.
What is Nigella Seed Tea?
Nigella seed tea is an herbal infusion made by steeping crushed or whole seeds of the Nigella sativa plant in hot water. These seeds are small, black, and slightly bitter with a warm, peppery, and nutty taste.
Common names include:
- Black seed
- Black cumin (not to be confused with regular cumin)
- Kalonji (India and surrounding regions)
- Habbat al-barakah (Arabic)
The plant has been used for thousands of years in traditional medicine systems such as Ayurveda and Unani. Nigella seeds are frequently incorporated into food, oils, supplements, and beverages. The tea form offers a mild and accessible way to consume its bioactive compounds without adding significant calories.
Active components often studied include:
- Thymoquinone
- Nigellidine
- Alpha-hederin
- Essential fatty acids
- Antioxidants
These compounds are associated with potential therapeutic effects, though tea preparations may contain lower concentrations than extracts or oils.
