The Warming Root of the Sage

Ginger is the pungent underground stem of Zingiber officinale, a plant of tropical Asia cultivated since antiquity and among the earliest of eastern spices to reach the West along the trade routes. Its most famous devotee is Confucius, whom the Analects record as never being without ginger when he ate, a small, precise detail of the sage's temperate way of life that fixed the spice in the Chinese moral imagination as a wholesome and clarifying food. Warming and stimulating to the taste, ginger was valued across Asia and Europe both in the kitchen and, as folk history records, as a comforting remedy for the cold stomach.

Ginger is one of the better-evidenced traditional remedies discussed in this atlas: multiple clinical trials and systematic reviews have found real, if modest, benefit for nausea, including morning sickness in pregnancy and nausea following chemotherapy, findings solid enough that ginger is recommended by some clinical guidelines as a genuine adjunct treatment rather than being dismissed as folklore, a comparatively rare case of an ancient warming remedy holding up reasonably well under modern controlled study. It is worth noting that this evidence concerns nausea specifically, and does not extend to the much wider range of ailments ginger has traditionally been recommended for, a distinction worth keeping in mind when weighing an old reputation against what has actually been tested.
