A dense, sharp, black-skinned winter radish far hotter than the spring table radish. Used for centuries as a digestive and liver-bile tonic, it is the most medicinally pointed of the radishes.
A potent liver-and-digestion tonic root for households carrying the metabolic and liver burdens of poor diet and chronic stress — folk medicine that holds up to scrutiny.
Black radish carries the highest glucosinolate load of the radishes, including compounds traditionally credited with stimulating bile flow and supporting liver detoxification — its folk reputation as a liver tonic tracks with measured choleretic activity. The crucifer chemistry supports phase-II detox enzymes relevant to cancer prevention. Pungent, fibrous, and near-zero in starch, it is a low-glycemic medicinal root.
Peel the thick black skin, then grate or slice thin. Salt and rest to mellow the heat. Eaten raw for full enzyme value, or in a traditional honey-and-radish cough syrup. Pungency mellows with cooking but so does the active compound load.
