Which of the following is a symptom of Internal Wind?

Internal Wind is a concept in Traditional Chinese Medicine that refers to a pathological condition characterized by a disturbance in the body's internal environment, often associated with excessive yang or heat conditions. Symptoms of Internal Wind can include convulsions, tremors, or spasms due to this disturbance.

The choice that describes extreme heat and convulsions directly aligns with the characteristics of Internal Wind, as these signs suggest a hyperactive state in the body where the presence of heat generates an internal tumult. Specifically, the connection between extreme heat and the manifestation of convulsions is a classic presentation of Internal Wind, indicating an overload of yang energy that can disrupt normal bodily functions and lead to involuntary movements or seizures.

Other options like a dull-pale complexion, heart palpitations, and scanty periods do not correlate with the typical presentation of Internal Wind. The dull-pale complexion is generally indicative of conditions associated with deficiency or stagnation rather than the dynamic and active state implied by Internal Wind. Heart palpitations may indicate various conditions, including emotional disturbances or heart issues, but not specifically the manifestation of Internal Wind. Scanty periods are often related to blood deficiency or hormonal imbalances, further distancing them from the characteristics of Internal Wind.
