Boosts the immune system
Kalonji has potential immune-boosting effects. It promotes the growth of immune cells that have anti-inflammatory effects and prevents the formation of inflammatory molecules.

So, nigella seeds may be able to help relieve allergy symptoms like bronchitis, asthma, and coughing.
Relieves pain and inflammation
Black cumin or kalonji contains terpenes like thymoquinone. They have anti-inflammatory and natural pain-relieving powers. They protect your body from inflammatory conditions like arthritis by stopping the production of inflammatory molecules.
Prevents microbial infection
Nigella sativa seeds and seed oil have antimicrobial properties. Thymoquinone extracted from the seeds is effective against bacteria, including Listeria, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Salmonella. It's also effective against fungi, viruses, and parasites.
Research shows that 6 grams of ground kalonji seeds and 12 grams of honey daily can help treat gastric ulcers. Kalonji’s antimicrobial properties help kill Helicobacter pylori, a bacterium that infects your gut and causes stomach ulcers.

Oxidative stress can lead to low or abnormal sperm production. It can result in infertility in males. Evidence suggests that herbs like kalonji can reduce oxidative stress and prevent male infertility.
Prevents acne and skin problems
Kalonji has plant-based compounds that protect the skin and promote wound healing. Its anti-inflammatory, antioxidant, and antimicrobial properties may also help heal burn wounds. In a clinical trial, 60 people were asked to apply black cumin gel twice daily. They showed reduced symptoms of acne without any side effects.
