Pogostemonis Herba (PH) is the dried aerial parts of Pogostemon cablin (Blanco) Benth, which is mainly distributed and used in Asian countries. PH is an aromatic damp-resolving drug in traditional Chinese medicine (TCM), which is usually used for the treatment of vomiting, chest tension, tiredness, abdominal pain, diarrhea, and headache. In this review, the summary of chemical constituents in the aerial parts, biological activities, history of uses, quality control methods, industrial applications, pharmacokinetics and network pharmacology are reported. By collating the chemical constituents of various parts of PH, a total of 174 components were identified, including 66 terpenes, 6 pyrones, 40 flavonoids, 21 phenylpropanoids, 9 steroids, 4 polysaccharides and 28 others. Pharmacological research has found that PH possesses multi-pharmacological activities, including regulating the gastrointestinal tract, inhibition of pathogenic microorganisms, and anti-inflammation, which provide more scientific interpretation for the clinical usage of PH. In addition, the shortcomings of the current research on PH and the recommendation of future studies on PH are analyzed. We hope this review can provide some insight for further research and applications of PH in future.
