The term "Cottonmouth" commonly refers to a venomous snake found in the southeastern United States. Known scientifically as Agkistrodon piscivorus, this snake is easily recognized by its distinctive yellow or greenish-brown coloration and its wide, triangular head. Cottonmouths are often found near water sources, such as swamps and rivers, where they hunt for fish and amphibians. In addition to the snake, "Cottonmouth" can also refer to a condition experienced by some people, characterized by a dry mouth. This can occur due to dehydration, anxiety, or certain medications. Staying hydrated and chewing gum can help alleviate this uncomfortable feeling.
