Changes in serum high density lipoprotein (HDL); menopausal women randomly assigned to Nigella sativa (N.S) or placebo groups were treated for 2 months and blood samples taken at baseline, and 1 and 2 months after the start of the intervention, and one month after cessation of intervention (FL), and used to evaluate serum HDL. Results are expressed as mean ± SD. *significant between N. S vs. placebo group at p < 0.05. Different letters on bars representing different intervals for the same group indicate significant difference between the intervals for the same treatment (p < 0.05).
