Quercetin

Biological activity

Antioxidant activity

  • It acts as strong antioxidant and helps to protect the body from oxidative damages
  • Consumption of quercetin is extremely useful for preventing the risk of developing chronic diseases as it is associated with decreasing the concentration of free radicals within body, which are considered as one of the leading cause of chronic diseases like cancers, diabetes, cardiovascular disease etc
  • It helps to prevent the oxidation of various important biological substances of body such as lipid, protein, DNA, RNA etc hence helps to sustain their functionality

Anti-inflammatory activity

  • It exerts potent anti-inflammatory activity and reduces the prevalence of chronic inflammatory diseases
  • It plays significant role in decreasing the concentration of TNFα or tumor necrosis factor alpha and IL-6 or interleukin-6 in body, which are considered as inflammatory markers. As it is associated with reducing the level of these inflammatory markers thus it helps to protect the body from inflammatory damages
  • It has seen that those arthritic patients (especially suffer from rheumatoid arthritis) who consume quercetin daily significantly improve their symptoms and it also helps in reducing arthritic pain

Anti-carcinogenic activity

  • It has strong anti-carcinogenic property that helps to decrease the level of carcinogens in body hence reduces the susceptibility of carcinoma
  • It is very effective for hindering the growth of tumor cells
  • It helps to protect the body from the harmful consequences of cancer by preventing metastasis
  • It also plays imperative role in inducing cancerous cell death
  • Its consumption is very effective for decreasing the prevalence of prostate, lymphoid, breast, adrenal, lung, liver, colon, bladder, blood and ovarian cancer

Antimicrobial activity

  • Its antimicrobial activity is responsible for decreasing the susceptibility of developing infectious diseases as it plays vital role in preventing the growth and reproduction of microbial cells
  • It is very effective against various viruses like adenovirus, Japanese encephalitis, herpes simplex virus and respiratory syncytial virus
  • It is incredibly effective against several bacteria also, which are responsible for causing infection especially in respiratory tract, urinary tract, skin, intestine and stomach

Health benefits

Role on nervous system

  • It plays imperative role in improving the functionality of nervous system
  • It has seen that it is closely related with increasing neurogenesis (it is the process of synthesizing new neuron in brain) and neuronal longevity by modulating a range of kinase signaling cascades like AKT/PKB tyrosine kinase, phophoinositide 3- kinase and Protein kinase C
  • It helps to protect every nerve cell from oxidative damages thus decreases the prevalence of neurodegenerative disorders
  • It is very effective for improving the symptoms of Alzheimer’s disease as well as Parkinson’s disease
  • It helps to prevent dementia as well

Role on cardio vascular system

  • It plays significant role in promoting cardiac health and functionality
  • It has seen that consumption of quercetin significantly decreases the rate of cardiac morbidity and mortality
  • It has hypolipidemic activity, which helps to decrease body fat percentage thus reduces the risk of fat deposition within blood vessels. As a result is helps to prevent clot formation within blood vessels hence decreases the risk of developing atherosclerosis
  • It is very effective for reducing the prevalence of coronary artery disease, angina pectoris, myocardial infarction, strokes and heart attacks
  • It provides a relaxing effect on blood vessels thus helps to reduce elevated blood pressure as well

Role on immunity

  • It helps to regulate the immunological responses of the body whenever necessary
