Nourishes Liver and Kidney Yin while enriching essence and Blood - classically used for dizziness, tinnitus, blurred vision, premature graying, and hair loss when deep deficiency and dryness are present.
Moistens the intestines and unblocks the bowels - the oily seed is especially useful for dry constipation in older adults, postpartum patients, or those recovering from prolonged illness.
Supports hair and skin through food-medicine tonification - widely used in medicinal foods, powders, and congee to gently restore constitutional depletion without strong heating or coldness.
Fits long-term deficiency recovery better than emergency treatment - Hei Zhi Ma works gradually by replenishing depleted substance rather than forcing rapid symptom suppression.
Secondary Actions
Classical texts sometimes use the name Hu Ma for sesame-related substances, and later writers worked to distinguish Hei Zhi Ma from flaxseed and other oily seeds with overlapping moistening actions.
Because it is pleasant tasting and food-grade, Hei Zhi Ma is one of the most approachable Liver-Kidney nourishing substances in the materia medica.
Classic Formulas
Qi Bao Mei Ran Dan (七宝美髯丹) - famous essence-and-blood tonic formula for premature graying, weak sinews, dizziness, and depletion patterns, using Hei Zhi Ma to support hair and the Liver-Kidney axis.
Qing Zao Jiu Fei Tang (清燥救肺汤) - dryness-rescuing Lung formula in which Hei Zhi Ma contributes moistening support when dryness injures fluids and the bowels become dry.
Classical References
Me and Qi describes Hei Zhi Ma as sweet and neutral, entering the Liver and Kidney channels to nourish essence and Blood, moisten the intestines, and benefit the hair, ears, and eyes.
Later classical discussions of formulas such as Qi Bao Mei Ran Dan made black sesame a standard adjunct for premature graying and deficiency-related hair loss because black-colored seeds were thought to strongly enter the Kidneys.
Traditional food therapy and medicinal-diet practice use Hei Zhi Ma extensively in paste, powder, congee, and pill forms, reinforcing its status as a medicine-food rather than a harsh corrective herb.
Modern Research
Active Compounds
Sesamin (lignan) - the best-known sesame lignan associated with antioxidant, antihypertensive, and lipid-regulating research
Sesamolin (lignan) - companion lignan with antioxidant and metabolic regulatory relevance
Sesamol (phenolic antioxidant) - a potent processed sesame antioxidant linked to anti-inflammatory and neuroprotective research
Black seed-coat anthocyanins and phenolics (pigmented polyphenols) - contribute color-specific antioxidant and anti-inflammatory interest in black sesame
Oleic and linoleic acids (fatty acids) - major oil components that help explain the seed's lubricating and nutritive profile
