This pattern in Traditional Chinese Medicine is seen in childhood nutritional impairment due to chronic parasitic infestation. This condition leads to Stagnation in the Middle Burner (Spleen and Stomach area), causing Spleen and Stomach injury. As a result, food stagnates in the Middle Burner, leading to poor nutrition distribution to the head and limbs.

This is manifested as a sallow complexion, emaciated limbs, and a large, distended abdomen. Over time, the Spleen Deficiency evolves into Empty Heat, contributing to feverishness, along with the internal heat generated by the accumulation itself.

The prolonged disturbance from parasites, coupled with reduced food intake and assimilation by the Spleen and Stomach, results in Blood Deficiency, evident in dry and coarse hair. This Deficiency primarily affects the Liver, leading to symptoms like dullness of the eyes and diminished vision acuity.

In this pattern, the parasite acts as a strong pathogenic influence against a backdrop of weak normal Qi. The pale tongue and frail pulse are diagnostic signs, reflecting the Deficiency of Spleen Qi and Liver Blood, characteristic of this pattern.
