“Cinnabaris Administration Leads to Tissue Mercury Accumulation in Rats, Predominantly in Intestinal Tract, Stomach, and Kidney, with Minimal Liver Damage and No Ethylmercury Detection or Brain Tissue Changes”

https://pubmed.ncbi.nlm.nih.gov/38114224

This study found that chronic administration of Cinnabaris, a traditional Chinese medicine, results in accumulation of inorganic mercury in rat tissues, mainly in the intestinal tract, stomach, and kidney, with potential liver damage, but no ethylmercury was detected and no significant brain tissue changes occurred.
