Arsenic, a metalloid, resembles food poisoning, interferes with phosphate. Arsenic and zinc form arsine, which smells bad. Cyanide, smells like bitter almonds. Interferes with cells using oxygen. It's found in the pits of almonds, apricots and apple seeds, in small amounts, and is used as an alternative form of chemotherapy. Thallium, radioactive, in medical imaging. Replaces Potassium in enzymes. Impairs protein digestion. Polonium creates free radicals. Ethylene glycol. Glycolic acid causes metabolic acidosis, and calcium oxalate crystals, which cause kidney damage. And it's implicated in feline leukemia, cats are susceptible to exposure because they lick their paws after walking through spilled antifreeze. Oleander, contains oleandrin and neriine. Acts like digitalis. But it's also part of an alternative cancer treatment. Arsenic was added to chicken feed for many years, and still might be in it, because it might cause weight gain. I wonder if it's still in our food supply, considering so many people are overweight and sickly. Arsenic is now contaminating rice, because the fields were sprayed heavily with it when they were once cotton fields. Arsenic is in poorly made wines. Arsenic is still a commonly used pesticide. Because arsenic interferes with phosphate, this could be why conventional crops sprayed with insecticides become dependent on phosphate fertilizers. Have in your first aide kit: food grade activated charcoal, Prussian blue.

Don't think "undedectable". Think "unsuspicious". Does your foe have bad eyes and a weak heart? Overdose them on blood pressure pills and pretend they mistook it for something else. They like to drink a bit too much? Methanol is your friend. Feel free to mprovise. But remember, I didn't tell you to kill anybody, murder is bad.

They should include how some person could get poisoned by these naturally. But I think aconite poisoning is the best because it acts as if the person had a heart attack and unless you’re looking for it specifically you won’t find it. But out of these ethylene glycol would be my favourite

To keep meat red in stores they pump carbon dioxide and monoxide into the non airtight packages but even though it soaks into the meat to keep it looking fresh they don’t have to put it into the ingredients because it technically isn’t an original ingredient therefore not their problem.

“Preservatives” in food, to enhance coloring and taste. And “cancer curing medicines” by B13 activists. Free radicals, sounds like that dangerous things that *alternative* “Doctors” who are not really doctors, but are quacks are pushing.

My father was poisoned with Arsenic and almost died, but thanks to a 3rd doctors opinion they saved him. He still suffered severe nerve loss and took years of rehabilitation to walk again. Arsenic may not be common today but it certainly happens.

A little more insight to the Oleander poisoning ,Timothy Waters was actually poisoned by David Wayne Sconce in an effort to keep him quiet about David's extracurricular activities with human cadavers such as stealing the gold teeth and fillings , & stealing body parts. Sconce was also violent towards mr. Waters before his death I believe he served five years for the mingling with human remains. while one witness said that they saw sconce slip something into Waters drink prosecutor said it wasn't definitive on how Waters got poisoned.

working in a hospital lab, we actually get tests for ethylene glycol and methanol back relatively quickly from an outside lab (about 2 hours) when docs suspect poisoning. it's quite common among hardcore alcoholics to poison themselves when they have no access to alcohol
