Abstract
To investigate effects of sodium fluoride (NaF) on the cerebellum cerebral hemisphere brain of rats and its possible amelioration by the popular Ayurvedic herbal health product triphala, adult female Wistar rats (Rattus novergicus) were administered 10 mg NaF/kg bw/day and 30 mg triphala/kg bw/day for 30 days. A significant decline in body and brain tissue weights after NaF treatment was noted. The decreased succinate dehydrogenase (SDH) activity indicated an alteration in mitochondrial structure and function by fluoride poisoning affecting energy metabolism. An increase in the total lipid could be the result of the inhibition of enzymes and reduction of fatty acid synthesis. Moreover, increased lipid peroxidation indicated an oxidative stress in the brain. These effects were correlated with histological changes and accumulation of fluoride in the neural tissue. However, these changes were ameliorated by co-supplementation of triphala with NaF. The antioxidant properties of the herbal product triphala therefore had an alleviating effect on NaF-induced neurotoxicity in rats.

Ameliorative effects of oleanolic acid on fluoride induced metabolic and oxidative dysfunctions in rat brain: experimental and biochemical studies
Beneficial effects of oleanolic acid on fluoride-induced oxidative stress and certain metabolic dysfunctions were studied in four regions of rat brain. Male Wistar rats were treated with sodium fluoride at a dose of 20 mg/kg b.w./day (orally) for 30 days . Results indicate marked reduction in acidic, basic and neutral

Protective effects of curcumin against fluoride-induced oxidative stress in the rat brain
We examined effects of a plant polyphenolic compound, curcumin, against fluoride-induced oxidative stress in the rat brain. Five experimental groups of male rats (10 animals each) were compared. Animals of these experimental groups were treated with curcumin (10 and 20 mg/kg body mass), vitamin C (10 mg/kg), and sample solvent

Pre and post natal exposure of fluoride induced oxidative macromolecular alterations in developing central nervous system of rat and amelioration by antioxidants.
The effect of fluoride exposure during gestation and post gestation periods were studied to check the status of oxidant, antioxidant and macromolecular changes in CNS and ameliorative role of antioxidants. The pregnant Wistar albino rats were exposed to 50 and 150 ppm fluoride in drinking water and the pups born

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

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 & 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

Fluoride Exposure Increases Metabolic Requirement for Calcium & Vitamin D
It is well known that individuals with nutrient deficiencies are more susceptible to fluoride toxicity, including fluoride's bone effects. As discussed in the following studies, fluoride increases the skeleton's need for calcium (and vitamin D) by increasing the amount of unmineralized tissue (osteoid) in the bone. When insufficient calcium and

Fluoride & Rickets
One of fluoride's most well-defined effects on bone tissue is it's ability to increase the osteoid (unmineralized bone) content of bone. When bones have too much osteoid, they become soft and prone to fracture -- a condition known as osteomalacia. When osteomalacia develops during childhood, it is called "rickets." The potential for fluoride
