The main component of pine cone is terpineol, and the volatile oil also has certain expectorant effect. It is speculated from the study of terpineol that its expectorant mechanism may be related to promoting the recovery of glandular lesions and cilia injury and enhancing the movement speed of tracheal mucus-cilia.
Extended data:
The antibacterial and anti-inflammatory effect of Songta decoction in vitro is weak, but the volatile oil has certain inhibitory effect on pneumococcus. The decoction can promote the recovery of pathological tissues of chronic trachea and bronchitis, reduce the infiltration of inflammatory cells and reduce goblet cells and mucus glands.
Some patients have dry mouth and dizziness after taking Baipisongta decoction, and some patients have mild edema, nausea, vomiting, abdominal pain and diarrhea.
