Background: Pogostemonis Herba, the dried aerial part of Pogostemon cablin Blanco, is a well-known materia medica in Asia that is widely used for syndrome of gastrointestinal dysfunctions.
Objective: This study was undertaken to examine whether Pogostemon cablin extract (PCe) might have any beneficial effect on hypoxia induced rabbit cardiomyocyte injury.
Materials And Methods: Isolated cardiomyocytes were divided into three groups and the changes of cell viability in cardiomyocytes of hypoxic and hypoxia/reoxygenation group were determined. The effect of PCe on reactive oxygen species (ROS) generation, intracellular formation of ROS was also measured by monitoring the 2',7'-dichlorofluorescein fluorescence.
Results: PCe effectively protected the cells against both the hypoxia and reoxygenation induced injury, and the protective effect of PCe is not mediated by interaction with adenosine triphosphate-sensitive K(+) channels. In the presence of PCe, production of ROS under chemical hypoxia was remarkably reduced which suggests that PCe might exert its effect as a ROS scavenger.
Conclusion: The present study provides clear evidence for the beneficial effect of PCe on cardiomyocyte injury during hypoxia or reoxygenation following prolonged hypoxia.

Patchouli is a valuable medicinal herb and cash crop in China, but viral infections cause significant yield losses. This study identified six viruses in patchouli transcriptome data, including the first-ever detection of East Asian Passiflora Virus (EAPV) in patchouli. RT-PCR validated three viruses from diseased patchouli plants in Haikou, China: telosma tosaic virus (TelMV), broad bean wilt virus-2 (BBWV-2), and pogostemom alphacytorhabdovirus 1 (PogACRV1_Pog).

(Patchouli), an essential medicinal plant in the family, faces significant challenges under continuous cropping (CC) obstacles. This study examined the rhizospheric soil bacterial communities of patchouli under four different CC years, zero (CK), one (T1), two (T2), and three (T3) years through high-throughput 16S rRNA gene amplicon sequencing. Results showed long-term CC led to significant soil properties and enzyme activity shifts.

Flowering is crucial for the reproductive success of plants. Patchouli (Pogostemon cablin), a widely utilized medicinal and aromatic plant from the Lamiaceae family, exhibits rare flowering and fails to produce seeds, thereby posing a challenge for plant evolution and breeding improvement. However, the mechanism underlying flowering in patchouli has not been investigated.
