Nestled within tiny, unassuming seeds lies a pharmacological treasure that has journeyed through millennia to captivate modern science.
Sesamum indicum Linn., commonly known as Till Safeed in Unani medicine and white sesame in global contexts, is far more than a culinary garnish or oil source. This ancient crop, among the oldest cultivated plants in human history, has been silently nourishing civilizations while guarding potent bioactive compounds that today stand at the forefront of nutritional and medical research [4][8].
Recent scientific investigations have begun validating what traditional healing systems have proclaimed for centuries: that these humble seeds possess extraordinary potential to combat some of humanity's most pressing health challenges, from cardiovascular disease to chronic inflammation and metabolic disorders.
Archaeological evidence suggests sesame was cultivated in Pakistan's ancient sites over 5000 years ago, with China adopting its use nearly as long ago [4].
The plant traveled through trade routes across Asia, Africa, and eventually the Americas, embedding itself in diverse cultural and medicinal traditions.
In Unani medicine, an ancient healing system still practiced today, Till Safeed has been documented as a therapeutic agent for numerous conditions—from digestive ailments to reproductive health issues [8].
Traditional applications varied widely across cultures: in Ayurveda, sesame oil was used for massage and rejuvenation therapies; in Traditional Chinese Medicine, it was prescribed to boost energy and calm the mind [4][6].
Sesame seeds pack an impressive 50-52% fatty acids by weight, predominantly healthy unsaturated fats including oleic acid and linoleic acid [4][9].
They contain 17-19% protein with a favorable amino acid profile, including significant amounts of methionine and tryptophan, which are often limiting in plant proteins.
Exceptionally rich in calcium (989 mg/100g), iron (14.8 mg/100g), magnesium (356 mg/100g), and zinc (7.2 mg/100g) [9].
| Nutrient | Amount per 100g | % Daily Value (Approx.) |
|---|---|---|
| Protein | 17-19 g | 34% |
| Fat | 49-52 g | 75% |
| Carbohydrates | 23.4 g | 8% |
| Fiber | 11.8-14 g | 56% |
| Calcium | 989 mg | 99% |
| Iron | 14.8 mg | 82% |
| Magnesium | 356 mg | 89% |
| Zinc | 7.2 mg | 48% |
| Vitamin B6 | 0.8 mg | 40% |

What truly sets Sesamum indicum apart in the botanical world is its exceptional phytochemical portfolio, particularly its unique lignan compounds. These bioactive plant chemicals, concentrated predominantly in the seed hull, include sesamin, sesamolin, sesamol, and sesaminol glucosides [9].
These lignans are responsible for sesame's impressive antioxidant properties and many of its documented health benefits.
Other significant phytochemicals include phytosterols (400-413 mg/100g), which contribute to cholesterol-lowering effects; phenolic acids including ferulic acid and vanillic acid; and flavonoids such as quercetin and kaempferol glycosides [8][4].
| Compound | Class | Concentration | Documented Effects |
|---|---|---|---|
| Sesamin | Lignan | 200-500 mg/100g | Antioxidant, anti-inflammatory, cholesterol-lowering |
| Sesamolin | Lignan | 200-300 mg/100g | Neuroprotective, antihypertensive, antimicrobial |
| Sesamol | Lignan | Variable | Radioprotective, hepatoprotective, antioxidant |
| Sesaminol glucosides | Lignan glycosides | Variable | Antioxidant, antimutagenic |
| γ-Tocopherol | Vitamin E isomer | 57.4 μg/100g | Anti-inflammatory, antioxidant |
| Phytosterols | Sterols | 400-413 mg/100g | Cholesterol-lowering, anti-cancer |

A 2025 systematic review and meta-analysis published in Nutrition & Metabolism analyzed data from 13 clinical trials involving 521 participants and found significant improvements in multiple cardiovascular risk factors following sesame supplementation [1].
The study reported notable reductions in glycated hemoglobin (HbA1c), C-reactive protein (CRP), and interleukin-6 (IL-6)—key markers of glycemic control and inflammation.
| Parameter | Standardized Mean Difference | Confidence Interval | P-value |
|---|---|---|---|
| HbA1c | -0.67 | -1.01, -0.32 | <0.001 |
| CRP | -0.51 | -0.96, -0.05 | 0.028 |
| IL-6 | -0.74 | -1.16, -0.32 | <0.001 |
| Fasting Blood Sugar | -0.57 | -1.16, 0.02 | 0.057 (ns) |
| Total Cholesterol | -0.39 | -0.80, 0.02 | 0.063 (ns) |

The genomic revolution now enables scientists to investigate the genetic basis of sesame's unique properties—recent advances include the identification of genes and QTLs related to yield, oil content, and stress tolerance [10].
Clinical research needs to address several unanswered questions, including optimal dosing regimens, long-term safety profiles, and synergistic effects with conventional pharmaceuticals.
More research is needed on the biotransformation of sesame lignans by gut microbiota and how this influences their bioavailability and activity [9].
Recent investigations have explored its use in water purification, with phytochemical extracts demonstrating impressive disinfection capabilities against E. coli and other pathogens [6].
The journey of Till Safeed from ancient remedy to subject of cutting-edge scientific investigation exemplifies the enduring value of ethnopharmacological knowledge.
What traditional healers understood through centuries of observational wisdom now finds validation through randomized controlled trials and molecular analyses [1][7]. This convergence of traditional and scientific knowledge offers a powerful model for exploring other medicinal plants.
Sesamum indicum Linn. represents far more than a culinary ingredient—it is a phytochemical treasure chest with demonstrated benefits for cardiovascular health, glycemic control, inflammation, and oxidative stress [1][9].
