The signs as poisons or toxins
Aries: VX, a nerve agent developed for no reason other than to be a bio-weapon. It causes violent muscle contractions followed by paralysis, asphyxiation, and death.
Taurus: Deadly nightshade, a plant that can be used as a hallucinogen at low doses. An overdose causes abnormally fast heart rate, loss of balance, and convulsions. A lethal overdose involves a lack of control over heart rate, breathing, and sweating followed by death.
Gemini: Sarin, a highly volatile nerve agent that’s been used in several terrorist attacks. It can cause effects as a liquid or a gas and leads to tightness in the chest followed by nausea, muscle convulsions, suffocation, and death.
Cancer: Amatoxin, a toxin produced by several species of poisonous mushrooms. It causes burns where it comes into contact with the body and leads to liver damage and eventual liver and/or kidney failure.
Leo: Ricin, a protein derived from castor seeds. It leads to swelling and bleeding in the digestive tract, followed shortly by low blood pressure, shock, organ failure, and death. It has also been used in terrorist attacks.
Virgo: Mercury, element 80 on periodic table. Exposure causes burning and itching along with the sensation of insects crawling on one’s skin or skin peeling from the body. Long-term exposure leads to severe brain damage and death.
Libra: Tetrodotoxin, a neurotoxin found in pufferfish and some other species of the same order. The toxin causes a lack of function in voluntary muscles, including the diaphragm, which leads to paralysis, asphyxiation, and death.
Scorpio: Cyanide, the chemical compound KCN. Results depend on exposure; low long-term exposure can cause eventual paralysis and increased chance of miscarriages, while high doses result in seizures, cardiac arrest, and death.
Sagittarius: Strychnine, an alkaloid derived from the Strychnos nux-vomica tree and used as a pesticide. In humans it causes dramatic and painful convulsions that can lead to muscles locking up and organs failing. Those exposed die of either asphyxiation or exhaustion from the convulsions.
Capricorn: Polonium, a radioactive metal and number 84 on the periodic table. It can cause death in extremely small doses, and long-term exposure leads to radiation poisoning, which can cause kidney or liver failure, cancer, and eventual death.
Aquarius: Arsenic, a toxic metal that is number 33 on the periodic table. Acute poisoning can lead to hair loss, muscle cramping, convulsions, and death. Long-term exposure, such as through groundwater, may lead to nightblindness, organ failure, cancer, and eventual death.
Pisces: Mustard gas, a chemical weapon used largely in World War I. It causes causes large chemical burns and blisters, including potential internal burns in the lungs. Even when these symptoms aren’t lethal, exposure may lead to severe health problems years later.
