Abstract
Flavonoids have been extensively studied and reported to possess widespread biological activities, including antioxidant and chelating properties. They have been proposed to exert beneficial effects in a multitude of diseased states generated due to oxidative stress. Therapeutic efficacy of oral administration of Silymarin and Quercetin after fluoride exposure (50 ppm in drinking water for 45 days) was investigated in rats. Animals exposed to fluoride showed a marked enhancement in reactive oxygen species (ROS), a significant decrease in reduced glutathione (GSH) in blood. In brain and kidney also, a significant elevation in ROS and Thiobarbituric Acid Substances (TBARS) level was noted accompanied by a significant decline in reduced/oxidized glutathione (GSH: GSSG) ratio. Furthermore, significant protection was observed in altered neurotransmitters level following the administration of Silymarin and Quercetin. Interestingly, both the flavonoids were able to reduce the level of fluoride from blood and kidney suggesting that the two flavonoids have the ability to bind fluoride ion too. It can be concluded from the results that, posttreatment with these flavonoids not only significantly protects against fluoride-induced oxidative stress but reduce its burden too from blood and tissues.

Protective effects of blackberry and quercetin on sodium fluoride-induced oxidative stress and histological changes in the hepatic, renal, testis and brain tissue of male rat
BACKGROUND: Sodium fluoride (NaF) intoxication is associated with oxidative stress and altered antioxidant defense mechanism. The present study was carried out to evaluate the potential protective role of blackberry and quercetin (Q) against NaF-induced oxidative stress and histological changes in liver, kidney, testis and brain tissues of rats. METHODS: The rats

Ameliorative effects of quercetin on sodium fluoride-induced oxidative stress in rat's kidney
OBJECTIVE: The in vivo nephroprotective effect of quercetin against sodium fluoride (NaF)-induced damage was studied. METHODS: Renal injury was induced by daily administration of NaF (600 ppm) through drinking water for 1 week. The levels of reduced glutathione (GSH), lipid peroxidation as well as superoxide dismutase and catalase activity of

Protective role of gallic acid on sodium fluoride induced oxidative stress in rat brain
Gallic acid is known as a potent antioxidant active compound of the edible and medicinal plant Peltiphyllum peltatum. The main objective of this study was to evaluate the neuroprotective effects of gallic acid against sodium fluoride induced oxidative stress in rat brain. Gallic acid (10 and 20 mg/kg) and vitamin C

Neuroprotective effects of methyl-3-O-methyl gallate against sodium fluoride-induced oxidative stress in the brain of rats
Methyl-3-O-methyl gallate (M3OMG) is a rare natural product that showed promising in vitro antioxidant activities. In this study, the protective role of synthetic M3OMG against sodium fluoride (NaF)-induced oxidative stress in rat brain was evaluated. Animals were treated with either M3OMG (10 and 20 mg/kg i.p.), vitamin C (10 mg/kg

Mitigating role of quercetin against sodium fluoride-induced oxidative stress in the rat brain
CONTEXT: Quercetin is a well known aglycone flavonoid that is widely found in different food sources. OBJECTIVE: In this study, the in vivo neuroprotective potential of quercetin against sodium fluoride-induced oxidative stress was evaluated. MATERIALS AND METHODS: Wistar rats were divided into five treatment groups and then subjected to daily

Fluoride & Oxidative Stress
A vast body of research demonstrates that fluoride exposure increases oxidative stress. Based on this research, it is believed that fluoride-induced oxidative stress is a key mechanism underlying the various toxic effects associated with fluoride exposure. It is also well established that fluoride's toxic effects can be ameliorated by exposure

Nutrient Deficiencies Enhance Fluoride Toxicity
It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,

Fluoride's Effect on Fetal Brain
The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts

Fluoride & IQ: 74 Studies
• As of May 2022, a total of 83 human studies have investigated the relationship between fluoride and human intelligence. • Of these investigations, 74 studies have reported that elevated fluoride exposure is associated with reduced IQ in humans. • The studies which reported an association of reduced IQ with exposure to

Fluoridation of drinking water and chronic kidney disease: Absence of evidence is not evidence of absence
A fairly substantial body of research indicates that patients with chronic renal insufficiency are at an increased risk of chronic fluoride toxicity. Patients with reduced glomerular filtration rates have a decreased ability to excrete fluoride in the urine. These patients may develop skeletal fluorosis even at 1 ppm fluoride in the drinking water.
