Lanxangia tsaoko, formerly Amomum tsao-ko, is a ginger-like plant known in English by the transliterated Chinese name cao guo (Chinese: 草果; pinyin: cǎoguǒ). It grows at high altitudes in Yunnan,[2] as well as the northern highlands of Vietnam.[3] Both wild and cultivated plants are used medicinally and also in cooking.[2]. It shows anti-quorum sensing and anti-biofilm activity on Staphylococcus aureus (Gram positive), Salmonella Typhimurium and Pseudomonas aeruginosa (Gram negative). [4]
