Similarly, gingerol from Zingiber officinale (ginger) acts on peripheral nerves to reduce gut hypersensitivity [49], and curcumin from Curcuma longa (turmeric) inhibits inflammatory mediators such as cyclooxygenase‐2 and TNF‐α, offering benefits for inflammatory bowel disease (IBD) and related disorders [50, 51, 52]. The gene discussed is TNF; the disease is irritable bowel syndrome.
