The pineal gland has been known as the ‘seat of soul’ for hundreds of years. Could fluoride, a ubiquitous vector of toxicity in the modern world, actually be calcifying this gland and literally turning it to stone? Research published in 2001 showed that fluoride (F) deposits in the pineal gland with age and is associated with enhanced gland calcification. Eleven aged cadavers were dissected and their pineal glands assayed: There was a positive correlation between pineal F[luoride] and pineal Ca[lcium] (r = 0.73, p<0.02) but no correlation between pineal F and bone F. By old age, the pineal gland has readily accumulated F and its F/Ca ratio is higher than bone.” This is the not the first research to implicate fluoride in contributing to so-called ectopic calcification, or the calcification of soft tissue. We address this in a previous report on the potential for fluoride to calcify the arteries. https://www.greenmedinfo.com/blog/fluoride-calcifier-soul
