Black sesame (hei zhi ma)

1. Overview
Black sesame — hei zhi ma — is one of the most prized Chinese tonic foods, treasured for its capacity to nourish Kidney essence (jing), Liver blood and Lung yin. Traditional accounts hold that long-term use prevents premature greying, supports fertility and longevity, and lubricates the bowel. The black colour signals its affinity for the water element and Kidney organ in TCM five-element theory.
