Is dragon fruit cooling or heating in nature?
Pitaya (dragon fruit) is considered a relatively “cooling” fruit in Traditional Chinese Medicine (TCM), despite being native to tropical regions—distinguishing it from many other tropical fruits.

First, although the pitaya’s skin is red, its flesh is white and its seeds black. According to TCM theory, white corresponds to the Lung channel and black to the Kidney channel; thus, both the flesh and seeds of pitaya enter the Lung and Kidney meridians, nourishing the body fluids of these two organs. Consequently, pitaya may help alleviate symptoms associated with Yin deficiency and internal heat.
Second, pitaya has a relatively low sugar content and is not overly sweet; therefore, consuming it does not generate excess stomach heat or “fire.”

Third, pitaya exerts a notable lubricating and laxative effect on the intestines. It can aid individuals suffering from constipation by facilitating the elimination of pathogenic heat through the gastrointestinal tract.
In summary, pitaya is classified as a cooling fruit in TCM; individuals with cold-damp constitutions or sensitivity to cold should consume it sparingly.
