سم (Poison) refers to any substance that can cause harm or death when introduced into the body. Poisons can be found in various forms, including liquids, solids, and gases. They can enter the body through ingestion, inhalation, or skin contact. Common examples of poisons include certain plants, chemicals, and heavy metals. The effects of سم can vary widely depending on the type and amount of poison, as well as the individual's health. Symptoms may range from mild irritation to severe illness or even death. Treatment often involves removing the poison from the body and providing supportive care, sometimes using antidotes specific to certain poisons.
