Organic poisons are naturally occurring toxins produced by the metabolic processes of living organisms. These toxins are often proteins, sometimes combined with other molecules. The term "organic," in this context, refers to its biological origin, not to the farming practices associated with the term "organic food." Unlike inorganic poisons, which are derived from non-living sources, organic poisons are created by living cells.
Examples of Organic Poisons:
- Ricin: A highly toxic protein found in castor beans. (https://www.cdc.gov/chemical-emergencies/chemical-fact-sheets/ricin.html) Ingesting even a small amount can be lethal.
- Natural Toxins in Food: Many foods contain naturally occurring toxins, albeit often in small quantities that don't pose a health risk. Examples include toxins found in certain fish and shellfish, ackee fruit (hypoglycin A), and beans (phytohaemagglutinin).

- Microcystins: Toxins produced by blue-green algae, which can contaminate water sources.
- Grayanotoxins: Found in some types of honey.
Distinguishing Organic from Inorganic Poisons:
It's crucial to differentiate organic poisons from inorganic poisons. While both are harmful, their sources and chemical structures differ significantly. For instance, arsenic exists in both organic and inorganic forms. Inorganic arsenic compounds are significantly more toxic than organic arsenic compounds.

The term "organic poison" is used in contrast to "inorganic poison" to highlight the biological origin of the toxin. The toxicity of a substance is determined by its chemical properties, not necessarily its organic or inorganic nature. A substance classified as "organic" may still be highly toxic, as demonstrated by examples like ricin.
The study of toxins, including organic poisons, is a significant area of toxicology. Understanding their sources, mechanisms of action, and potential effects on human health is vital for developing effective preventative measures and treatments.
