There is an increased interest in the potential health benefits of nutraceutical therapies, such as Anethum graveolens (dill). Therefore, this systematic review and meta-analysis aimed to evaluate the effects of Anethum graveolens supplementation on lipid profiles and glycemic indices in adults. A systematic search was performed for literature published through November 2020 via PubMed/Medline, Scopus, ISI Web of Science, and Embase to find randomized controlled trials (RCTs) evaluating the effects of oral supplementation with A. graveolens on lipid profile and measures of glycemic control in adults. The random-effects model was applied to establish the weighted mean difference (WMD) and associated 95% confidence intervals (CI). Seven RCTs with a total number of 330 subjects were included in the final analysis. Pooled results indicated that A. graveolens supplementation significantly decreased low-density lipoprotein cholesterol (LDL) concentration (WMD: -15.64 mg/dL; 95% CI: -24.55 to -6.73; P = 0.001), serum insulin (WMD: -2.28 μU/ml; 95% CI: -3.62 to -0.93; P = 0.001), and HOMA-IR (WMD: -1.06; 95% CI: -1.91 to -0.20; P = 0.01). However, there was no significant effect on serum total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL), and fasting blood glucose (FBS). Subgroup analysis suggested that using A. graveolens in higher doses and long-term duration had beneficial effects on lipid profiles. Dose-response analysis also showed a significant reduction in FBS at doses of 1500 mg/d. The present meta-analysis indicated that Anethum graveolens could exert favorable effects on insulin resistance and serum LDL. Further research is necessary to confirm our findings.
Background The objective of this study was to investigate the effects of Anethum graveolens (dill) powder supplementation on glycemic control, lipid profile, some antioxidants and inflammatory markers, and gastrointestinal symptoms in patients with type 2 diabetes. Materials and methods In this study, 42 patients with type 2 diabetes were randomly allocated to intervention and control groups and received either 3 g/day dill powder or placebo (3 capsules/day, 1 g each). Fasting blood sugar, insulin, homeostatic model assessment of insulin resistance, lipid profile, high-sensitivity C-reactive protein, total antioxidant capacity, malondialdehyde and gastrointestinal symptoms were measured in all of the subjects at baseline and postintervention. Results The dill powder supplementation significantly decreased the mean serum levels of insulin, homeostatic model assessment of insulin resistance, low-density lipoprotein cholesterol, total cholesterol and malondialdehyde in the intervention group in comparison with the baseline measurements (P Conclusion Dill powder supplementation can be effective in controlling the glycemic, lipid, stress oxidative and gastrointestinal symptoms in patients with type 2 diabetes.

Mechanistic basis
This use is associated with the plant's anti-inflammatory action. Further evidence for that pharmacology:
Dill (Anethum graveolens L.) has been shown strong antioxidative and immune propertise, but the precise potency and action mechanisms remain largely elusive. This study is to dissect the different fractions' antioxidant power and antiinflammatory function. We extracted 4 fractions from China original dill with ether (DI-E), ethyl acetate (DI-EA), n-butanol (DI-B) and water (DI-W), and performed 4 different kinds of antioxidative analysis together with vitamine C (Vc): DPPH, ABTS, reducing power and TPTZ-FRAP. For correlated compounds in antioxidant assays Folin-Ciocalteu's analysis was performed. For antiinflammation, cell proliferation by MTT, NO molecules and interleukin-1 and 6 in supernatant were detected by Griess reaction and Elisa, respectively, and gene expression of inducible nitric oxide synthase (iNOS) was analyzed by RT-PCR. The strength of antioxidant activity was Vc > DI-EA > DI-B > DI-W > DI-E. Folin-Ciocalteu's analysis showed that antioxidant power was correlated to phenolic compounds. However, in antiinflammatory assays DI-E was most active one by cell proliferation, iNOS's gene expression, and secretion of interleukin IL-1 and 6 in macrophage RAW264.7. The antioxidant fraction and antiinflammatory fraction of the dill were determined. The certain fractions of dill may be strong at antioxidation, but weak at antiinflammation, vice versa. Thus dill has anti-ageing and anticancer potential, a good resource for functional food and ancillary drugs of rehabilitation.
