Lemongrass

Research corpus coverage

Chemistry notes

• CHEMISTRY: Relevant reported constituents include citral; myrcene; geraniol; constituent presence alone does not establish clinical efficacy.

Traditional / historical use

Documented traditional use — not a claim of established efficacy.

• TRADITIONAL: Lemongrass has been used for digestive complaints; fever; anxiety; this records historical/traditional use and does not establish efficacy.

  MODERATE · regulatory monograph · EMA European Union herbal monographs and list entries

Modern evidence

• EVIDENCE: For the major use set (digestive complaints; fever; anxiety), the evidence assessment is insufficient: Insufficient clinical evidence; small trials and preclinical data predominate.

  LOW · randomized controlled trial · EMA European Union herbal monographs and list entries

Forms used traditionally

A listed form does not imply it suits every plant part, or that one preparation is interchangeable with another — see the plant’s own notes below.
