Natural Phytotherapeutic Antioxidants in the Treatment of Mercury Intoxication-A Review
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6156483/Under findings.
As you can see, mercury is highly imunotoxic.
I noticed in poisers(including me) elevated bleedeng oral mucosa in pois.
Inflammation findings: Inflammation caused by the influence of heavy inorganic mercury causes the tendency to bleed in gingiva and oral mucosa. It increases the salivary secretion, causing sensation of metallic taste in the mouth. Gingiva, a gray line is formed, especially when the oral hygiene is bad.29
Endocrine findings: Thyroid function tests (TFTs) are thought to change levels. (Free-T3 and Free-T4). The most affected hormones by mercury are insulin, estrogen, testosterone and adrenaline.40-43
Neurological system findings: In humans, adverse neurological effects have been reported following high concentration acute mercury vapor inhalation. Generally, perceptual, personal, conceptual, and motor confusion are reported. The most important symptoms are tremor, emotional tenderness, insomnia, memory loss, neuromuscular changes (weakness, muscle atrophy and muscle withdrawal), headache and polyneuropathy.23,31-35 Exposure to mercury compounds at an early stage causes long-lasting and permanent neurobehavioral and neurochemical irregularities. Like Parkinson's disease and Alzheimer's disease.36
The elimination of mercury from the body is very difficult...
