Abstract
Summary: Oral administration of sodium fluoride (NaF, 6 and 12 mg/kg body weight/day) to Swiss male albino mice for 30 days caused significant, dose-dependent reduction in DNA, RNA, and protein contents in cerebral hemisphere, cerebellum, and medulla oblongata of the 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 administrations of NaF and black tea extract for 30 days cause significant amelioration in all parameters studied.

Amelioration by black tea of sodium fluoride-induced changes in protein content of cerebral hemisphere, cerebellum and medulla oblongata in brain region of mice.
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

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:
-
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

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

Two New Members of CsFEXs Export Fluoride Coupled Proton Gradients and Participate in Reducing the Fluoride Accumulation in Low-Fluoride Tea Cultivars
The accumulation of fluoride in tea leaves from various cultivars exhibits significant differences. However, the molecular basis and mechanism remains largely unknown. Here, we reported that two genes of CsFEXs (Fluoride export genes in C. sinensis), CsFEX1 and CsFEX2 transport fluoride out of cells, alleviate the cellular fluoride toxin and

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

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 & IQ: 76 Studies
Note: See the Updated list of fluoride IQ studies at https://fluoridealert.org/researchers/fluoride-iq-studies/the-fluoride-iq-studies/ • As of July 18, 2022, a total of 85 human studies have investigated the relationship between fluoride and human intelligence. • Of these investigations, 76 studies have reported that elevated fluoride exposure is associated with reduced IQ in humans. • The studies

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.

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
