Quercetin, a flavonol contained in various vegetables and herbal medicines, has various biological activities including anti-cancer, anti-allergic and anti-oxidative activities. However, low oral bioavailability of quercetin due to insolubility in water has limited its use as a food additive or
The antiallergic properties of hop water extract (HWE) were studied by evaluating histamine release from human basophilic KU812 cells induced by calcium ionophore A23187. HWE significantly inhibited histamine release, but boiling water extract and chloroform-methanol extract did not show any
BACKGROUND
Flavonoids are nutrients that exert anti-allergic effects. We investigated the preventative effect of enzymatically modified isoquercitrin (EMIQ), a flavonoid, to relieve the symptoms of Japanese cedar pollinosis.
METHODS
In a parallel-group, double-blind placebo-controlled study design,
Free radicals are widely known to be the major cause of human diseases such as neurodegenerative diseases, cancer, allergy and autoimmune diseases. Human cells are equipped with a powerful natural antioxidant enzyme network. However, antioxidants, particularly those originating from natural sources
BACKGROUND
Accumulating evidence suggests an association between autism spectrum disorders (ASD) and inflammation in brain regions related to cognitive function. The natural flavonoid luteolin has antioxidant, anti-inflammatory, mast cell-blocking, and neuroprotective effects. It was shown to
Among the foremost common flavonoids within the human diet, quercetin glycosides possess neuroprotective, cardioprotective, anti-oxidative, chemopreventive, and anti-allergic properties. Isoquercetin is one such promising candidate with anti-diabetic potential. However, complete studies of its
