Sancai Tuhui (Vol. 60)

Illustration of Cold Prickly-Heat Sores original: "Lengfei Chuang Tu" (冷疿瘡圖). In Traditional Chinese Medicine, "Cold" (Leng) indicates a condition that lacks the redness and intense heat of typical inflammation, while "Prickly-Heat" (Fei) refers to a miliary rash or small eruptions. This suggests a skin condition triggered by stagnant fluids or cold-dampness.

The accompanying woodcut illustration depicts a man seated cross-legged on a traditional mat. He is shown with distinct sores and lesions concentrated on his cheeks and chin, providing a clear visual reference for the clinical presentation of this specific dermatological condition. Beside him sits a small bowl, likely intended for holding medicinal washes or the preparation of topical ointments used in the treatment of such eruptions. This visual guide would have allowed a physician to identify the ailment through "observation," the first of the four diagnostic pillars in Chinese medicine.
