Dr. Weeks’ Comment: As a beekeeper who uses raw honey in my medical practice and, as a doctor who recommends black cumin seed oil to people suffering with cancer and other inflammatory degenerative illnesses, this article delighted me!

Abstract:
To evaluate in vitro antitumor effects of bee honey (BH) and Nigella sativa (NS) on HepG2 through their antioxidant and apoptotic activities.
METHODS:
HepG2 cell line was treated with different concentrations of diluted unfractionated BH and different concentrations of alcohol extract of NS. Exposure lasted for different time durations (6-72 hours), both dose-response and time course-response were conducted. Cell viability was tested by trypan blue exclusion test. Total antioxidant status and caspase-3 activity were estimated in the cell lysate. Nitric oxide levels were measured in culture supernatants of both treated and untreated HepG2 at all indicated times.
RESULTS:
Treatment of HepG2 cells with BH and NS leads to a significant decrease in both the number of viable HepG2 cells and the levels of nitric oxide on one hand, but improvement of the total antioxidant status and caspase-3 activity on the other, especially in HepG2 cells treated with higher doses of BH and NS (20% and 5000 μg/mL, respectively) and for longer duration (72 hours).
CONCLUSIONS:
BH and NS are effective in reducing the viability of HepG2 cells, improving their antioxidant status and inducing their apoptotic death.
