Why people make this tonic
This is one of Nourilo’s quiet favorites — black soybeans dry-roasted until their skins crack open, then steeped in sweet rice vinegar in a glass jar. In traditional food-therapy thinking, black beans are linked with the kidneys and black rice vinegar is associated with antioxidant support, circulation, and keeping hair dark. It takes about a month and a half before it is ready, but it keeps for a long time and a spoonful a day is an easy habit.
What studies say about the key ingredients
Traditional use is not the same as clinical proof. Here is the strongest human research we found for each ingredient, limitations included.
- Black soybeans
Systolic blood pressure fell more in the black soy peptide group (-9.69 mm Hg) than in the placebo group (-2.91 mm Hg) after baseline adjustment. Plasma malondialdehyde decreased and superoxide dismutase activity increased compared with placebo.Limitation: Used an isolated peptide supplement rather than whole black soybeans, and followed participants for only 8 weeks, so the results may not apply to food intake.PubMed 23924691
