Researchers evaluated 10 different NS extracts, and ranked the extract provided by Sabinsa’s parent company and manufacturing arm, Sami Labs, at the top. It surpassed the second ranking extract in terms of the active constituent, thymoquinone (TQ), by more than 300%.
Anti-inflammatory and immunomodulating properties are among the most valued in anti-asthma herbal products. Sabinsa’s Nigellin had the highest effects in suppressing the release of cytokines IL-2, IL-6, and PGE2 in T-lymphocytes and also in monocytes hindering the expression on IL-2 and PGE2. These are among the most active cytokines involved in asthmatic conditions. The investigators noted a positive relationship between the TQ level in the preparations and its inhibitory potency on IL-6 and PGE2.
However, PGE2 does exhibit beneficial bronchodilatory effects in human lung epithelial cells and Sabinsa’s extract showed an enhanced PGE2 expression in A549 human epithelial cells lines, demonstrating an interesting activity behavior of the maximum-TQ containing Sabinsa’s extract.
The results presented in this paper formed the biochemical basis of a subsequently conducted clinical trial.
Asthma is a debilitating disease afflicting 25 million people in the U.S. and 334 million globally according to some estimates. It tends to flare up sharply due to external factors such as pollution and allergens.
Nigella sativa and its preparations have been referenced extensively in traditional healthcare systems ranging from Ayurvedic and Unani to Arabic and Prophetic for prevention and treatment of asthma, making it a candidate for study by modern researchers. Lack of standardization has, however, hampered researchers in evaluating the material’s efficacy in the past.
“This emerging antioxidant ingredient has traditionally been used in the management of numerous health conditions, with recent research beginning to validate historically reported benefits,“ said Sabinsa Founder Dr. Muhammed Majeed. “Sabinsa has a track record of developing and marketing products for supporting human health rooted in traditional knowledge expanded through innovation. In this case we relied upon use of supercritical fluid extraction (SCFE) technology to provide an active solution.”
Sabinsa’s Nigellin represents patent-pending, solvent-free, SCFE black cumin seed extracts, standardized to contain thymoquinone. Nigellin is available as oil (Nigellin BCS - Amber), and defatted black and white powders (Nigellin BCS – Onyx, and Nigellin BCS - Pearl, respectively).
