Quercetin (/ˈkwɜːrsətɪn/) is a flavonoid compound naturally found in various plants such as apples, grapes, and onions. The spelling of this word is explained through the use of the International Phonetic Alphabet (IPA). The symbol /k/ represents the hard "c" sound, the symbol /w/ represents the "wh" sound in "where", and the symbol /ɜːr/ represents the "er" sound in "her". The symbol /s/ represents the "s" sound, and the symbol /tɪn/ represents the "tin" sound.

Quercetin is a flavonoid, a type of plant pigment, that is found in a variety of fruits, vegetables, and grains. It is known for its antioxidant properties and is considered one of the most abundant and widely distributed flavonoids in the plant kingdom. Quercetin is commonly found in foods such as apples, onions, berries, grapes, citrus fruits, broccoli, and leafy green vegetables.
This natural compound has been studied extensively for its potential health benefits. It has been shown to have anti-inflammatory, anti-viral, anti-cancer, and anti-allergic properties. Quercetin is believed to work by scavenging harmful free radicals in the body, which helps protect cells from damage and reduce oxidative stress.
In addition to its antioxidant activities, quercetin has also been shown to support cardiovascular health by promoting healthy blood circulation and reducing the risk of heart diseases. It may help lower blood pressure and cholesterol levels, as well as reduce the risk of blood clots.
Quercetin is also known for its potential immune-boosting effects. It has been studied for its ability to enhance the function of immune cells, such as natural killer cells and T cells, which are important in defending the body against infections.
While quercetin is naturally present in many foods, it is also available in supplement form. These supplements are often marketed for their potential health benefits, but it is important to note that more research is needed to fully understand the effectiveness and safety of quercetin supplementation.
The word "quercetin" is derived from the Latin word "quercetum", meaning "oak tree". It is named after Quercus, the Latin genus for the oak tree, which belongs to the Fagaceae family. Quercetin is a flavonoid compound found in various fruits, vegetables, and plants, including the bark, leaves, and fruits of oak trees. The name "quercetin" reflects its initial discovery and isolation from oak bark in the early 19th century.
