Quick Summary

Sesame (Sesamum indicum) is a nutrient-rich oilseed crop widely used for its seeds and oil. Clinical evidence from randomized controlled trials and meta-analyses suggests that sesame supplementation or consumption may have benefits for glycemic control, cardiovascular risk factors, inflammatory biomarkers, antioxidant status, and pain management in humans. While effects appear promising, the certainty of evidence is typically low to moderate due to small study sizes, heterogeneity, and methodological issues. Sesame oil has also been studied topically for infusion-related phlebitis and traumatic limb pain. Safety data are limited, and further high-quality clinical research is required for conclusive findings.

What is it?

Sesame is an annual flowering plant known for its edible seeds, which are rich in oils, proteins, and antioxidants. The seeds and oil extracted from Sesamum indicum are commonly used in cooking, traditional medicine, and as dietary supplements worldwide.

Traditional Uses

Traditionally, sesame seeds and oil have been used for nutritional purposes and in folk medicine to support cardiovascular health, reduce inflammation, enhance energy, and soothe skin conditions. Topical sesame oil has also been employed to manage wounds and musculoskeletal discomfort.

Active Compounds

Sesame seeds and oil contain several bioactive compounds including lignans (sesamin, sesamolin), unsaturated fatty acids, antioxidants, and phytosterols. These elements are thought to contribute to its potential effects on metabolism, inflammation, and oxidative stress.

Potential Benefits with Evidence Levels

Cardiometabolic Risk Factors

Meta-analyses of randomized controlled trials indicate that sesame supplementation may reduce blood pressure, improve lipid profiles (e.g., lower total cholesterol and triglycerides, raise HDL cholesterol), enhance glycemic control by decreasing fasting blood glucose and HbA1c, reduce inflammatory biomarkers such as IL-6 and CRP, and boost antioxidant enzyme activity.

Evidence Level: Moderate to low certainty due to study heterogeneity and small sample sizes.

  • PMID 41799776: Reduction in blood pressure, glucose, HbA1c, and liver enzymes after sesame supplementation.
  • PMID 41089589: Lower BMI, weight, blood pressure, and improved lipid profiles but rated very low certainty.
  • PMID 40069782: Dose-response meta-analysis showing improvements in HbA1c, CRP, IL-6, and lipids.
  • PMID 35673414: Sesame oil consumption lowered fasting blood glucose, HbA1c, blood pressure, and BMI.

Glycemic Control in Type 2 Diabetes

Randomized controlled trials and meta-analyses support that sesame consumption or supplementation may reduce fasting blood glucose and HbA1c levels in individuals with type 2 diabetes.

Evidence Level: Moderate certainty.

  • PMID 37317803: Meta-analysis of 8 trials showed significant glycemic improvements in type 2 diabetes patients.
  • PMID 34707665: Confirmation of hypoglycemic effects in diabetes patients.

Reduction of Inflammation

Some clinical trials suggest sesame intake can reduce serum levels of the inflammatory biomarker interleukin-6 (IL-6), though effects on other markers such as CRP and TNF-α are less conclusive.

Evidence Level: Low to moderate certainty.

  • PMID 34760018: Sesame intake significantly reduced IL-6 but showed no significant effects on CRP or TNF-α.

Antioxidant and Exercise Recovery Support

Limited clinical trial evidence in athletes suggests that sesame supplementation may enhance antioxidant enzyme levels (e.g., GPx, SOD) and reduce oxidative stress markers following aerobic exercise.

Evidence Level: Limited clinical trial evidence.

  • PMID 41637231: Systematic review shows improved antioxidant defenses and reduced oxidative stress with sesame and aerobic exercise.

Topical Use for Infusion-Related Phlebitis and Traumatic Limb Pain

Topical application of sesame oil alongside standard care may reduce incidence and severity of infusion-related phlebitis and help alleviate acute traumatic limb pain in adults.

Evidence Level: Moderate certainty with some methodological limitations.

  • PMID 39743002: Beneficial effects of topical sesame oil in managing infusion-related phlebitis.
  • PMID 38822706: Topical sesame oil massage reduced pain scores after limb trauma.

Iron Deficiency Anemia Adjunct

Sesame jaggery ball supplementation as an adjunct to oral iron therapy showed improvements in hemoglobin, serum ferritin, and body weight in children with moderate iron deficiency anemia.

Evidence Level: Low certainty from a single open-label randomized controlled trial.

  • PMID 40224691: Increases in hemoglobin and iron parameters with added sesame jaggery balls in children.

Side Effects

No consistent or serious adverse effects have been reported with sesame supplementation or topical use in controlled human studies. Mild gastrointestinal symptoms or skin reactions are uncommon but may be underreported. Overall, sesame appears to be well tolerated.

Drug Interactions

There is no clinical evidence on drug interactions with sesame or sesame-derived products. Due to limited safety data, interactions with medications remain uncharacterized and caution is advised.

Who Should Avoid It

Caution is recommended for individuals with known sesame allergy due to the allergenic potential of sesame seeds and products. No explicit contraindications were reported in the clinical evidence reviewed.

Evidence Limitations

  • Many clinical trials had small sample sizes and short durations.
  • Considerable heterogeneity and methodological limitations exist across studies.
  • Adverse effects and safety parameters were often poorly reported.
  • Several meta-analyses rated the certainty of evidence as low or very low due to risk of bias and inconsistency.
  • Evidence is lacking regarding safety during pregnancy and breastfeeding, drug interactions, and contraindications.
  • The long-term safety and effectiveness of sesame use remain unclear.
  • More well-designed, larger randomized controlled trials with standardized sesame preparations are needed.
