Black Sesame
Sesamum indicum L.
Black sesame holds a place of near-mythical reverence in Korean traditional medicine. The Donguibogam calls it 거승 (巨勝) — literally 'The Greatest Victory' — proclaiming it supreme among the eight grains. Its other classical name, 호마 (胡麻), tells a geographical story: 胡 means 'from foreign lands' (referring to western regions beyond China) and 麻 means 'hemp,' describing how the plant was brought east along ancient trade routes and resembled hemp in appearance. Korean scholar-physicians prized it above almost all other foods for longevity. The legendary preparation method 구증구포 — steaming and sun-drying nine times — was not merely culinary ritual but a precise alchemical process believed to transform the seeds' nature, making their essence fully absorbable by the human body. In Korean folk tradition, families would prepare 구증구포 black sesame pills as precious gifts for elderly parents, a practice that embodied filial devotion through the patience and care required for each of the nine cycles.

Seasonal Availability
Sesame is harvested in early autumn (September-October) in Korea. Freshly harvested and roasted seeds have the most intense nutty aroma. Dried seeds and oil are available year-round.
Complementary Ingredients (궁합 재료)

Processing Methods (법제)
The supreme preparation method from Donguibogam: steaming and sun-drying nine times transforms the seeds, dramatically increasing bioavailability of nutrients, removing any harsh qualities, and concentrating medicinal potency. Each cycle deepens the color and enriches the flavor.
Gentle roasting in a dry pan activates aromatic oils and makes the seeds easier to digest. The most common everyday preparation.
Grinding breaks the tiny seed coat so the body can absorb the nutrients. Whole seeds often pass through undigested.
Consumption Tips by Health Goal
Brain health
Steam black sesame seeds with rice wine, sun-dry, then grind to powder. Take as a daily supplement mixed into porridge or warm water.
Circulation
Cook black sesame into rice regularly or grind into powder and consume frequently with meals. Consistent daily intake is key.
Kidney health
Roast and grind to fine powder. Take 9g three times daily with warm rice wine, or mix with honey and ginger water for those who avoid alcohol.
Anti-aging
Process through 구증구포 (steam and sun-dry 9 times), then eat as a long-term daily tonic. Traditionally consumed for years without interruption.
Immunity
Combine black sesame with soybean and jujube, process all together through 구증구포, then form into small pills. Take daily as a comprehensive tonic.
Culinary Profile
Flavor
