Is a scalloped tongue always due to dampness?

Generally, scalloped tongue refers to the condition where there are tooth indentations along the edges of the tongue. While scalloped tongue is associated with excessive dampness in the body, it is not necessarily caused solely by dampness. The detailed analysis is as follows:

Scalloped tongue is mostly caused by an enlarged tongue being pressed against the teeth, and it is considered an abnormal tongue morphology, often accompanied by symptoms such as sticky bowel movements and fatigue. Excessive dampness may weaken the spleen and stomach's digestive and transforming functions, thereby affecting fluid metabolism and leading to internal accumulation of dampness, which can trigger scalloped tongue. However, dampness is not the only contributing factor; scalloped tongue may also be related to dry mouth, weight gain, or chronic mouth breathing. Patients with scalloped tongue are advised to seek medical guidance for treatment using herbal formulas such as Bu Zhong Yi Qi Wan, Xiang Sha Liu Jun Zi Wan, or Jian Pi Wan.

In daily life, maintaining healthy habits is important. Engaging in physical activities such as running, hiking, or hula hooping can promote blood circulation and help eliminate excess dampness from the body. Additionally, consuming moderate amounts of diuretic foods such as red beans, lotus seeds, and yam is beneficial, while avoiding cold, greasy, raw, or chilled foods can support overall health.
