A sudden and significant increase in body temperature, as measured by touch or with a thermometer. Fever is often accompanied by other symptoms, including pale, dry skin, sweating, cold chills, weakness, malaise, headache, and changes in breathing. There can be alternating conditions of dry, cold shivering and feelings of heat and sweating or combinations of both, such as cold and sweating.

What Is Fever?

From Modern Western Medicine

A fever is defined as a body temperature above 98.6°F when measured orally, and 99.8°F when measured from the rectum.

Most fevers are caused by bacterial or viral infections. Fevers are triggered by the body’s immune systems, specifically by macrophage and CD4 cells. These cells produce cytokins, which are chemical messengers that signal the brain to raise the body temperature in an effort to destroy the invading microorganism.

Fever may also accompany other conditions, such as dehydration, heart attack, and tumors of the lymphatic system. Its function is not understood in these cases.

From Traditional Medicine

Fever is not of itself a disease, but a response initiated by the body to cure an underlying disease. In short, a fever is part of the solution to illness and therefore should not be repressed unless it gets over 103°F. Brain damage can occur if a fever is allowed to reach 106°F. Most fevers never go above 102°F, and most last only a few days. In the meantime, they do much to assisting the body in its attempts to destroy and eliminate from the system the causes of the underlying disease. Hippocrates once said, “Give me fever and I will cure all disease.”

The exception is in the case of an infant. Children are far more sensitive to changes in temperature and therefore all fever warrant consultation and supervision by a medical doctor.

Chinese Medicine

In Chinese medicine, fever is a sign of an exterior condition, which means that the body surfaces that are exposed directly to the environment are affected first. The most common conditions considered external are fevers, chill, colds, and flu. To balance such conditions, we must choose herbs that are more expansive and reach toward the periphery of the body and those that open the sweat glands to sweat out the exterior disease factor lodged near the surface. This is not the time to take in strengthening, salty, or building foods as these will trap pathogens inside the body. Allow the person to sweat, but not to the point of exhaustion. If there is weakness with the fever and not much improvement, use herbal preparations that build the protective qi such as fresh gingerroot or cinnamon twig tea.
