TriNutra has announced a patent-pending study and review on the phytochemical compound thymoquinone, found in Nigella sativa (black seed) oil. The study compared the antifungal and antibacterial properties of different black seed oil compositions to investigate the ingredient’s range of antimicrobial activity.
The study compared four different compositions of the oil based on the percentage of thymoquinone (TQ) and low or high free fatty acid (FFA) content. Results showed low TQ, high FFA oil did not inhibit fungal growth and the low TQ, low FFA provided moderate support. However, the oils containing 3% thymoquinone showed the most potent inhibition of M. furfur and C. albicans fungi, with the low FFA oil delivering the best results. The oils were also tested on the bacteria S. aureus.
All of the tested black seed oils effectively inhibited its growth. The researchers say an additional component or combination of them (not yet identified) is likely responsible for the anti-bacterial effect by the oil. The study concluded that cold-pressed black seed oil standardised to 3% thymoquinone with low free fatty acid is a safe option to regulate the growth of key microorganisms influencing skin health and to assist in balancing the skin and gut microbiome.
“Detailed research into black seed oil compositions for skin health is still new and we are proud to be able to spearhead efforts to better understand how thymoquinone benefits different aspects of our skin,” said Dr Liki von Oppen-Bezalel, PhD, TriNutra’s Business Development Director and a contributor to the study.
”Regulating growth of S. aureus, C. albicans and M. furfur with the unique composition of black seed oil with 3% thymoquinone and low free fatty acid will play an important and long-term role in maintaining skin homeostasis. No need to settle for less when ingredients like ThymoQuin and B’utyQuin already meet the qualifications needed for both ‘beauty from within’ and cosmetic applications.”
This research follows an already completed application study using the company’s standardised black seed oil for treatment of scalp redness, itch, seborrhea and scaling. The study conducted on humans showed significant scalp soothing and relief of redness, scaling, seborrhoea and itch after no later than two weeks of use.
Extracted using a patented cold-press process, the company’s ThymoQuin and B’utyQuin are black seed oils standardised to 3% thymoquinone with very low free fatty acid.
