Abstract
Oral administration of sodium fluoride (NaF, 6 and 12 mg/kg body weight/day) to Swiss strain male albino mice for 30 days caused significant dose-dependant reduction in the content of acidic, basic, neutral, and total protein in cerebral hemisphere, cerebellum and medulla oblongata region of brain. After 30 days of NaF treatment, followed by withdrawal of treatment for 30 days, partial but significant amelioration occurred. Administration of 2% black tea extract alone for 30 days did not cause any significant effect. However, concurrent administration of NaF and black tea extract for 30 days caused significant amelioration in all parameters studied.

Mitigation of sodium fluoride induced toxicity in mice brain by black tea infusion.
SUMMARY: In an extension of previous work on fluoride (F) toxicity in a group of 80 Swiss albino mice, the mitigating effects of polyphenols in black tea on the F-induced increase in glycogen, cholesterol, and total lipids in the cerebral hemisphere (CH), cerebellum (CB), and medulla oblongata (MO) regions of

Black tea extract mitigation of NaF-induced lipid peroxidation in different regions of mice brains.
SUMMARY: As part of our investigation of fluoride toxicity effects in a group of 80 Swiss albino adult male mice, we examined the mitigating effects of black tea extract (BTE) on the F-induced enzymatic and non-enzymatic parameters of oxidative stress in the cerebral hemisphere (CH), cerebellum (CB), and medulla oblongata (MO) of the

Public-health risks from tea drinking: Fluoride exposure.
Aims: Due to new evidence on fluoride neurotoxicity during early life, this study examined maternal exposure to fluoride through tea consumption in a low-fluoride region and measured fluoride releases from commercially available teas (tea bags and loose teas) to determine the need to limit fluoride exposure. Methods:
-
Combination of fluoride and endosulfan induced teratogenicity and developmental toxicity in Swiss albino mice exposed during organogenesis.
The present investigation was conducted to evaluate the teratogenic and developmental toxicity of fluoride and endosulfan alone and in combination in pregnant Swiss albino mice exposed during the organogenetic period (5-14 days) of gestation. Fluoride (25.1 mg/kg body weight in water) and endosulfan (1.8 mg/kg bw by oral intubation) when

Tealeaves may release or absorb fluoride, depending on the fluoride content of water.
As the tea plant (Camellia sinensis) is known to accumulate fluoride from the soil, the tealeaves may contain high concentrations of fluoride, which is easily released during infusion. In this study, we have tested the possible effect of original fluoride concentration in the water on the fluoride release from tea.

Exposure Pathways Linked to Skeletal Fluorosis
Excessive fluoride exposure from any source -- and from all sources combined -- can cause skeletal fluorosis. Some exposure pathways , however, have been specifically identified as placing individuals at risk of skeletal fluorosis. These exposure pathways include: Fluoridated Water for Kidney Patients Excessive Tea Consumption High-Fluoride Well Water Industrial Fluoride Exposure Fluorinated Pharmaceuticals (Voriconazole

The Lancet: Fluoride Studies in a Patient with Arthritis
It is possible that fluoride intake from tea may be sufficient to cause fluorosis, and I report here a case which gives some evidence for this.

Skeletal Fluorosis in the U.S.
Although there has been a notable absence of systematic studies on skeletal fluorosis in the U.S., the available evidence indicates that the consumption of artificially fluoridated water is likely to cause skeletal fluorosis and other forms of bone disease in people with kidney disease and other vulnerable populations.

Tea Intake Is a Risk Factor for Skeletal Fluorosis
A number of recent studies have found that heavy tea drinkers can develop skeletal fluorosis - a bone disease caused by excessive intake of fluoride.

Fluoride Affects Learning & Memory in Animals
An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out
