The Poison Fluoride Is Contaminated!
Few on this site think highly of fluoride.
You may wonder how do you contaminate poison?
For newbies: “Fluorine has played a significant role in insect control since about 1896 when sodium fluoride and various iron fluorides were patented in England as insecticides. Sodium fluoride was used in the United States for cockroach control before 1900 and was introduced in 1915 for the control of poultry lice.”
In short fluoride was patented as an insect and rat poison.
