Description
Luteolin, in the form of glycoside exists in many plants, these plants with a dragonhead, pepper, wild chrysanthemum, honeysuckle, perilla content is higher. Has antitussive and expectorant effects. According to a new study, respiratory symptoms of cough, expectoration, gasp, are associated with chronic airway inflammation. Such as bronchial asthma, chronic obstructive pulmonary disease, chronic pharyngitis, such as allergic rhinitis caused by cough, expectoration, gasp, that were with the local inflammatory infiltration, the presence of inflammation and the immune response of airway chaos, often appear in patients with airway hyperresponsiveness. Treatment of chronic inflammatory infiltration of the airway should be eliminated first. Glucocorticoids are commonly used to eliminate airway inflammation. However, the side effects of glucocorticoids are more, and it is not suitable for long-term use. Studies have shown that luteolin inhibited the phosphorylation of macrophage, inhibit the activity of the transcription factor NF KB, can inhibit the lipopolysaccharide (LPS) - induced macrophages to produce cytokines IL-6 and TNF. The two cytokines play a very important role in the inflammatory mechanism, which is a sensitive indicator of the degree of inflammation. Luteolin can improve IFN- gamma, reduce specific Ig-E, reduce the infiltration of eosinophils. Additionally, luteolin in addition to anti-inflammatory, anti allergic effects outside, also has inhibition of PDE, anti SARS, HIV virus characteristics, the reason for inhibiting the activity of SARS virus S protein, thereby preventing it from entering the host cell. For the treatment of COPD, bronchial asthma, and chronic pharyngitis, allergic rhinitis caused by chronic cough.
