Definition
This section has been translated automatically.

Petasin belongs to a group of spasmolytic and antiphlogistically active bicyclic sesquiterpenes (petasins), which are mainly found in extracts of Petsides hybridus, the common or common butterbur. Besides petasin, other bicyclic sesquiterpenes are found in extracts of Petsides hybridus such as: neopetasin, isopetasin. The petasins are essentially determining the efficacy of Petasitidis rhizoma.

Pharmacodynamics (Effect)
This section has been translated automatically.

In experimental studies, petasins have an anti-inflammatory effect, inhibit phosphodiesterase and reduce albumin-induced allergic reactions. In other studies, an anti-allergic effect, possibly through inhibition of eosinophil granulocytes, was demonstrated. In vitro studies, petasin significantly inhibited proliferation and migration of human colon carcinoma cell lines and induced apoptosis . The results suggest that petasin is a potential candidate for colon cancer therapy (Lyu X et al. 2019). Further results suggest similar effects in prostate carcinoma and melanoma (Wang ZH et al. 2015; Guo L et al. 2020).
