According to a study published by "Molecules (Basel, Switzerland)", Pseudognaphalium affine (D. Don) Anderb. is a medicinal and edible plant used in folk medicine to treat cough, asthma, and COPD. The study evaluated the effect of Pseudognaphalium affine (D. Don) Anderb. extract (GAE) using in vivo and in vitro investigations. In a rat COPD model, the administration of GAE significantly ameliorated lung damage and pulmonary function by inhibiting pro-inflammatory cytokine production. Western blot and real-time PCR results showed that GAE could suppress the nuclear translocation of nuclear factor-kappa B (NF-κB). Furthermore, GAE protected against tumor necrosis factor (TNF)-α induced inflammatory response in BEA2-B cells and inhibited the NF-κB pathway.
The primary pharmacological activities of this plant are shown in the list below.
- anti-COPD
- anti-inflammatory
- astringent
- tissue-protective
- vulnerary
