Quercetin is a plant-derived chemical, called a phytochemical, found in certain types of plants, fruits, and vegetables. It is often responsible for giving plants, flowers, fruits and vegetables their color. The color of red apples and onions is caused by quercetin.
Quercetin is one of a group of phytochemicals known as flavonoids, most of which are responsible to some extent for coloring a plant product. Flavonoids, and quercetin in particular, may offer a number of benefits to humans. In addition to the aesthetic value of plant coloring, they may offer the practical benefit of improving health to some extent.
For example, quercetin is known to have several uses in the medical field. It is an antihistamine that can be used to reduce allergy symptoms. It can also be used to reduce inflammation for those with arthritis. Quercetin can also help reduce the number of free radicals in the body. These harmful particles are known to contribute to cancer and heart disease.
Quercetin can be taken in two forms. It is most commonly ingested through natural consumption of fruits and vegetables which contain significant amounts of the chemical. However, it is also available in capsule form for those who wish to take it this way. It is the method of choice for those who really expect to use quercetin to reduce the symptoms of the disease.
Quercetin may be a popular natural remedy for allergies and inflammatory disorders due to its lack of side effects. There are no known harmful side effects, although it may have some interaction with some forms of chemotherapy. Further studies are needed to determine whether this interaction is positive, negative or neutral.
For those wishing to use quercetin as an antihistamine, it is suggested that the daily dose should not exceed 600mg. It is recommended not to take it all at once, but in several doses throughout the day. To get quercetin in such numbers, you need to take it as a supplement as one apple has about 13mg of quercetin.
Quercetin is also generally considered non-toxic. Studies conducted on quercetin toxicity have shown no harmful effects between low-dose and high-dose groups. The only side effect mentioned is that some in the high-dose group experienced greater weight loss than those in the low-dose group.
