Quick Summary

Dill (Anethum graveolens) is an aromatic herb from the Apiaceae family historically used for managing primary dysmenorrhea, lipid profiles, glycemic control, and labor duration. Clinical evidence from randomized controlled trials (RCTs) and systematic reviews supports potential benefits in reducing menstrual pain and labor duration, as well as improving some lipid parameters and insulin resistance. However, the quality of the evidence varies and further high-quality studies are needed to confirm its efficacy and safety.

What is it?

Dill is an annual herbaceous plant native to the Mediterranean and widely cultivated for its aromatic leaves and seeds. It is commonly used as a culinary herb and has a history of traditional medicinal usage in various cultures.

Traditional Uses

  • Management of menstrual cramps (primary dysmenorrhea)
  • Supporting lipid and blood sugar control
  • Reducing duration of labor during childbirth
  • General digestive aid and anti-inflammatory purposes

Active Compounds

Dill contains various phytochemicals, including essential oils (such as carvone and limonene), flavonoids, and phenolic compounds, which are believed to contribute to its biological activities.

Potential Benefits with Evidence Levels

  • Management of primary dysmenorrhea (painful menstrual cramps)
    Evidence Level: Moderate
    A 2026 systematic review and meta-analysis reported significant reductions in both the duration and severity of dysmenorrhea with dill compared to standard treatments like NSAIDs; however, some included studies had methodological limitations.
  • Reduction of labor duration
    Evidence Level: Low to Moderate
    Systematic reviews of RCTs have shown that dill seed use may significantly shorten the first, second, and third stages of labor. This evidence is based on a small number of trials with some risk of bias.
  • Improvement in lipid profile and glycemic control
    Evidence Level: Low to Moderate
    Meta-analyses of trials indicate that dill supplementation may reduce LDL cholesterol, triglycerides, serum insulin, and insulin resistance markers (HOMA-IR). Effects on total cholesterol, HDL cholesterol, and fasting blood glucose were inconsistent. The evidence is limited by small sample sizes and study heterogeneity.
  • Potential anti-inflammatory and antioxidant effects
    Evidence Level: Insufficient clinical evidence
    Preclinical studies and traditional use suggest that dill and its essential oils may have anti-inflammatory and antioxidant properties, but robust clinical trials in humans are lacking.
  • Use as an herbal adjunct treatment for stroke recovery (combined formula)
    Evidence Level: Preliminary clinical evidence
    A single RCT using a combined extract of black sticky rice and dill showed improvements in stroke biomarkers and motor function recovery; however, findings are limited to the combined formulation and short-term follow-up.

Side Effects

Dill is generally considered safe when used in typical dietary amounts and in clinical settings. Few adverse effects have been reported, mostly mild gastrointestinal symptoms which were rare and inconsistently observed. No serious adverse events attributable solely to dill have been documented in clinical trials.

Drug Interactions

There is no specific clinical evidence of drug interactions with dill. Nevertheless, due to its phytochemical constituents, possible interactions with anticoagulants or drugs metabolized by cytochrome P450 enzymes cannot be ruled out. Caution and further research are warranted.

Who Should Avoid It

  • Individuals with known allergies to plants in the Apiaceae family
  • Pregnant or breastfeeding women should use dill cautiously due to limited safety data, despite some evidence supporting use of dill seed to reduce labor duration in low-risk pregnancies
  • People with sensitive digestive systems may want to monitor for mild gastrointestinal discomfort

Evidence Limitations

  • Many clinical studies have small sample sizes and risks of bias
  • Considerable variability in dill types, doses, and preparations used across studies
  • Short follow-up durations in most trials
  • Limited long-term safety data and insufficient information for use in pregnancy or breastfeeding
  • Some findings arise from multi-herb combinations limiting attribution solely to dill
  • Few direct comparative trials against standard therapies exist
