In vitro study | Farrerol observably reduces the production of inflammatory mediators including IL-1β, IL-6, TNF-α, COX-2, and iNOS in LPS-induced RAW264.7 cells via suppressing AKT, ERK1/2, JNK1/2, and NF-κB p65 phosphorylation. Farrerol attenuates β-amyloid-induced oxidative stress and inflammation through Nrf2/Keap1 pathway in a microglia cell line. Farrerol inhibits angiogenesis through Akt/mTOR, Erk and Jak2/Stat3 signal pathway. Farrerol overcomes the invasiveness of lung squamous cell carcinoma cells by regulating the expression of inducers of epithelial mesenchymal transition. Farrerol ameliorates acetaminophen-induced hepatotoxicity via activation of Nrf2 and autophagy. |
In vivo study | Farrerol protects dopaminergic neurons in a rat model of lipopolysaccharide-induced Parkinson's disease by suppressing the activation of the AKT and NF-κB signaling pathways. |

expectorant | Rhododendron is an expectorant drug extracted from Manshanhong and other Rhododendron plants. It has been artificially synthesized and directly acts on the respiratory tract Mucosa, promotes cilia movement, enhances the function of trachea and bronchus to mechanically remove foreign bodies, can break the acidic glycoprotein fiber in sputum, reduce the salivary acid content, and reduce the sputum viscosity, sputum becomes thinner and easy to cough up, while gradually reducing the amount of sputum. The expectorant effect for patients with chronic bronchitis is definite, the curative effect is long-lasting and stable, so that the amount of sputum is significantly reduced, the viscosity is reduced, and the symptoms are reduced. Clinically, it is mainly used for phlegm viscosity caused by chronic bronchitis. The tablets are 50~100mg per tablet. Oral 1 day 3 times, 1 time 50~100mg. Use with caution in patients with liver history and liver insufficiency. |
biological activity | Farrerol is an important active ingredient in azalea, with antioxidant and anti-inflammatory activities. |
