Pogostone or dhelwangin is a naturally occurring organic compound with the formula C₁₂H₁₆O₄. Classified as a secondary metabolite, primarily found in patchouli, a member of the mint family Lamiaceae. This plant has historically been used in traditional Chinese medicine to treat ailments such as the common cold, nausea, diarrhea, headache, and fever, and is also applied for its antifungal properties. Pogostone was first identified in 1969 as the major antimicrobial constituent of Pogostemonis Herba, the dried aerial parts of patchouli used in herbal preparations.
