A staple of the Chinese household medicine cabinet. The formula dates to the Song-dynasty 《太平惠民和剂局方》. Warning: the liquid version contains alcohol, so drivers switch to 藿香正气软胶囊 (soft capsules).

The 正气 here is TCM jargon for "upright qi" - the body’s own defensive energy - not the everyday "righteousness" meaning.
