Chia seeds also have a very high concentration of antioxidants, containing 1047 units of myrecetin, quercetin, kaemferol, caffeic acid, chlorogenic acid, and they are especially rich in vitamin C.
You can get quercetin in your diet by eating red apples and red onions since quercetin is the phytochemical that contributes to the red coloration.
More research is needed to establish the effectiveness of quercetin, but many people still swear by it for treating their hay fever symptoms.
One reason this tea may be so helpful is that it contains quercetin, as evidenced by the red color of the tea.
Quercetin should be taken as early as six to eight weeks before the start of allergy season for best results.
Quercetin has been shown to block the production of histamines that can cause itchy eyes and runny nose.
The rich red color of this tea comes from the quercetin present in the leaves of the rooibos plant.
If you take the drugs cyclosporine or nifedipine, you should not take quercetin.
A pleasant way to get quercetin is to have a cup of rooibos tea.
A-pyrone condenses with the benzene ring to form coumarin and isocoumarin; benzo-'y-pyrone constitutes the nucleus of several vegetable colouring matters (chrysin, fisetin, quercetin, &c., which are derivatives of flavone or phenyl benzo-y-pyrone); dibenzo--ypyrone is known as xanthone; related to this substance are fluorane (and fluorescein), fluorone, fluorime, pyronine, &c. The pyridine ring condenses with the benzene ring to form quinoline and isoquinoline; acridine and phenanthridine are dibenzo-pyridines; naphthalene gives rise to a-and /3-naphthoquinolines and the anthrapyridines; anthracene gives anthraquinoline; while two pyridine nuclei connected by an intermediate benzene nucleus give the phenanthrolines.
