Organic Nigella Aqueous Extract
Also known as: black cumin, kalonji, black seed, Nigella sativa
Overview
*Nigella sativa*, commonly known as black cumin or kalonji, is a flowering plant native to the Mediterranean region and South Asia. Its seeds are a rich source of bioactive compounds, particularly thymoquinone, and have been used in traditional medicine for centuries due to their health-promoting properties. The extract has gained popularity for its anti-inflammatory, antioxidant, and immunomodulatory effects, aiding conditions like allergic rhinitis and rheumatoid arthritis. Various forms such as oil, capsules, and aqueous extracts are available, suggesting versatility in administration. Although research on *Nigella sativa* is moderately advanced, displaying promising benefits across diverse health issues, the quality of studies varies significantly, with some presenting methodological flaws that necessitate cautious interpretation of the findings.
Benefits
Research highlights several potential benefits of *Nigella sativa*, backed by clinical evidence. Notably, a meta-analysis of randomized controlled trials (RCTs) indicates significant symptom improvement in allergic rhinitis (odds ratio = 4.24, p < 0.00001). Clinical studies have documented reductions in the Disease Activity Score (DAS28) in rheumatoid arthritis patients and consequent symptom improvements. Additionally, systematic reviews suggest that *Nigella sativa* may promote liver and kidney health by reducing markers like alkaline phosphatase and aspartate aminotransferase. There is emerging evidence for its role in managing blood glucose levels in type 2 diabetes, though this remains less established. Overall, effects tend to be most pronounced with consistent use over 2 to 12 weeks.
How it works
*Nigella sativa* exerts its effects via multiple biological pathways, primarily through its active compound thymoquinone. It exhibits anti-inflammatory effects by inhibiting pro-inflammatory cytokines such as IL-6 and TNF-α. Thymoquinone also enhances antioxidant activity by increasing superoxide dismutase (SOD) and catalase levels, reducing oxidative stress. Furthermore, it modulates immune responses by altering T cell ratios and inhibits the NF-κB pathway, which plays a pivotal role in inflammation regulation, thus showcasing its multifaceted interaction with biological systems.
Side effects
*Nigella sativa* is generally well-tolerated, though some common side effects include transient nasal dryness, hoarseness, nausea, and gastric discomfort; these are not significantly higher than control groups. Uncommon adverse effects may occur in 1-5% of users, including stomach aches, while rare side effects (less than 1%) are not consistently observed in research. Potential drug interactions, particularly with antidiabetic medications, necessitate cautious monitoring. Although no major contraindications exist, it's advisable for pregnant and breastfeeding individuals to exercise caution due to insufficient safety data. Patients with chronic conditions should consult their healthcare providers before starting supplementation to mitigate dose-dependent risks.
Dosage
Effective dosage of *Nigella sativa* varies based on the condition. A minimum effective dose of 1 to 3 grams per day is suggested, with oil dosages typically ranging from 1-2 grams daily for allergic rhinitis and rheumatoid arthritis management. Higher doses over 3 grams daily may elevate the risk of side effects, including raised blood urea nitrogen levels, requiring careful management. While specific timing is not critical, administering it with meals is recommended to enhance absorption, especially when taken with fatty foods. The bioavailability of its compounds also varies with preparation methods and specific product formulations.
