The normal human body temperature ranges from 97 to 99°F (36 to 37°C).
Fever is defined as a temporary increase in the body's temperature above normal, typically 100.4°F (38°C) and higher. It is the first response of the immune system to infection or injury. It can also be caused by inflammatory diseases such as rheumatoid arthritis, and external factors like heat exhaustion.
Common symptoms associated with fever include chills, sweating, headaches, muscle aches, fatigue, lack of appetite, irritability, and dehydration, all of which can be easily treated at home; however, high temperatures accompanied by seizures, mental confusion, and difficulty breathing require immediate medical attention.

There are many plants with anti-inflammatory, antipyretic, and diaphoretic properties that can help reduce body temperature.
