  • DaSilva N et al. Anti-melanogenic potential of thymoquinone isolated from black cumin (Nigella sativa L) [as Thymocid™] seed oil. University of Rhode Island: INBRE Poster Presentation. 2017. - Tyrosinase and tyrosinase-related protein-1 (TRP-1) and TRP-2 plays a major role in melanin synthesis. Supports youthful skin by inhibiting Tyrosinase and melanin production to look skin tone more even. In an in vitro study, TQ’s de-pigmenting ability against B16F10 melanoma cells was not caused by direct inhibition of the tyrosinase enzyme, but by inhibition of tyrosinase processing and maturation in the melanoma cells. This effect is associated with TQ’s ability to down regulate gene and protein expressions of MITF, TYRP-1 and TYRP-2.

Vol 9(No 2): 751. doi: 10.4172/2155-9600.1000751 The results of this study found that a high fat diet increased blood pressure and fasting blood glucose compared to control. Further the high fat diet group given black cumin seed oil, saw a reduction in blood pressure and fasting blood glucose compared to those fed a high ft diet alone; offering support for the use of thymoquinone to support metabolic health.
