Answer 1

Sure a story...we believe you, the judge may not but we do! LMAO!!!

Answer 2

One possible option may be prussic acid :
Prussic acid, cyanide, or hydrocyanic acid are all terms relating to the same toxic substance. It is one of the most rapidly acting toxins which affects mammals. Cyanide is a lethal ingredient that has been used in rodent and vermin killers.

Understanding Prussic Acid Poisoning
A number of common plants may accumulate large quantities of prussic acid (cyanogenic compounds). Sorghums and related species readily accumulate these compounds. These cyanogenic compounds are located in epidermal cells (outer tissue) of the plant, while the enzymes which enable prussic acid production are located in the mesophyll cells (leaf tissue).

Any event that causes the plant cell to rupture allowing the cyanogenic compound and the enzyme to combine will produce prussic acid. Plant cells can be ruptured by cutting, wilting, freezing, drought, crushing, trampling, chewing, or chopping. Once plants containing prussic acid have been consumed, the toxin rapidly enters the blood stream and is transported throughout the body of the animal. Prussic acid inhibits oxygen utilization by the cells in the animal's body. In essence, the animal suffocates. Ruminant animals (cattle and sheep) are more susceptible to prussic acid poisoning than non-ruminant animals because the ruminal microorganisms have enzymes which will release prussic acid in the animal's digestive tract.

Clinical Signs
Prussic acid is a potent, rapidly acting poison. Signs of prussic acid poisoning can occur within 15 to 20 minutes to a few hours after animals consume the toxic forage. Animals are often found dead. Clinical signs, when noticed, occur in rapid succession. Excitement, rapid pulse, and generalized muscle tremors occur initially, followed by rapid and labored breathing, staggering, and collapse. There may be salivation (drooling), lacrimation (runny eyes) and voiding of urine and feces. The mucous membranes are usually bright pink, and the blood will be a characteristic bright cherry red.

Answer 3

I don't know of one that resembles heart **disease**, but many authors have used Prussic Acid (Hydrocyanic acid, HCN solution) to "cause" a heart attack.

Answer 4

yes NaCN
