Also known as: Black cumin, Black seed, Kalonji, Roman coriander, Fennel flower, Pungent seeds, Nigella sativa

Overview

Nigella sativa, commonly known as black cumin, is a flowering plant native to the Middle East and South Asia. Traditionally, its seeds have been used for health benefits and as a culinary spice. The key bioactive component, thymoquinone (TQ), is linked to its pharmacological properties. Black cumin is known for its potential effects on improving cardiometabolic health, treating allergic rhinitis, and providing significant antioxidant and anti-inflammatory benefits. Current research on *N. sativa* includes systematic reviews and meta-analyses showing moderate to high evidence for its efficacy, although the quality varies, necessitating further studies. Its natural forms include seed powder and oil, both of which are used in supplements and foods.

Benefits

Research suggests that *Nigella sativa* may offer numerous health benefits, including: 1) **Reduction in Cardiometabolic Indicators**: Significant decreases in fasting plasma glucose, hemoglobin A1c, and cholesterol levels have been observed, particularly in individuals with prediabetes and type 2 diabetes mellitus (T2DM) (Evidence Strength: Moderate) [1]. 2) **Treatment for Allergic Rhinitis**: Meta-analyses indicate *N. sativa* improves symptoms and overall efficacy in allergic rhinitis treatment (OR = 4.24) [2]. 3) **Antioxidant and Anti-inflammatory Properties**: TQ helps mitigate oxidative stress and inflammation, contributing to protective effects against various diseases [3][4]. Evidence is especially strong regarding its benefits for at-risk populations, such as those with T2DM and allergic conditions.

How it works

The mechanism of action of *Nigella sativa* is multifaceted, primarily attributed to thymoquinone (TQ). TQ modulates oxidative stress and inflammation pathways by inhibiting pro-inflammatory mediators such as NF-κB and enhancing antioxidant enzyme activity. It also supports immunity and energy metabolism by influencing various body systems, including cardiovascular and metabolic pathways. This synergy contributes to its diverse pharmacological effects and its ability to alleviate symptoms across different health conditions.

Side effects

Generally, *Nigella sativa* is well tolerated with a favorable safety profile. Common side effects (>5%) are not well documented, but experiences suggest low incidence. Uncommon (<5%) and rare (<1%) side effects are not extensively reported; however, caution is recommended. Potential drug interactions may occur with antidiabetic and antihypertensive medications given its effects on glucose and lipid metabolism. Pregnant and breastfeeding women should consult healthcare providers due to limited research on safety. Patients with diabetes should closely monitor blood glucose levels during supplementation. Overall, while *N. sativa* appears safe in moderate amounts, specific populations may require more cautious use.

Dosage

The minimum effective dose of *Nigella sativa* is suggested to be greater than 1 g per day, particularly for benefits related to cardiometabolic health. Studies indicate that optimal doses range from 1 to 3 g per day. There is no well-defined maximum safe dose, but high dosages over 3 g per day should be approached with caution due to insufficient data. Consistent daily intake is endorsed, although specific timing strategies have not been established. Both the seed powder and oil forms are utilized, and bioavailability may vary based on the chosen form and dietary factors.
