Brief Introduction of Luteolin Supplements Luteolin supplements are a kind of nutrition made of natural flavonoid compound which normally exists in various kinds of plants. It has many different pharmacological activities such as antiallergic, anti-tumor, antiviral and antibiosis. In clinical treatment, http://www.nfextracts.com/luteolin-supplements is mainly used as the treatment of cardiovascular disease, SARS and hepatitis.
Luteolin mainly exists in various kinds of plants as the form of glucoside. Dragonhead, hot pepper, mother chrysanthemum, honeysuckle and purple perilla all have large contents of luteolin. In traditional Chinese medicine, these plants are used to relieve cough and eliminate phlegm. It is in acicular crystal shape and has a color of yellow. Its melting point can reach to 328℃ and can slightly soluble in water. It has a faintly acid character and stable character under the normal condition. Based on the newest research, respiratory symptoms such as cough, expectoration and gasp are related to airway chronic inflammation. Bronchial asthma, chronic obstructive pulmonary disease and chronic pharyngitis are related to partial inflammation infiltration. The existence of inflammation would make an immune response chaos of airway and increase the airway reactivity. As the treatment, removing the chronic inflammation infiltration of airway is in the first place. At present, glucocorticoid always is used as the main method to remove the airway inflammation. But it has a lot of side effect and is not suitable to have a long term
use. Researches show that luteolin can restrain the phosphorylation of macrophage and activity of transcription factor which play very important roles in inflammation mechanism and is the sensitive index to reflect the inflammation degree. In addition, luteolin can improve IFN-y, reduce specificity Ig-E and infiltration of eosinophilic granulocyte. Besides, luteolin can also restrain PDE and against the virus characters of SARS and HIV. That is because it can restrain the activity of former S protein of SARS and prevent it get into the host cell.
