3. Triple Burner Differentiation

This system classifies exogenous febrile diseases into upper, middle, and lower burner syndromes based on the site of onset and the severity and stage of progression.

(1) Upper Burner Syndrome

Hand Taiyin Lung Syndrome: headache, fever with chills (more heat than cold), spontaneous sweating and thirst, cough, floating and rapid pulse or a prominent pulse at both cun positions—indicating the need to release the exterior and disperse lung qi. Treatment includes Sangju Yin and Yinqiao San. Hand Jueyin Pericardium Syndrome: dark red tongue, confusion and delirium, or stiff tongue and cold limbs. Treatment involves clearing heart fire and opening the orifices, using Angong Niuhuang Wan and Zixue Dan (from "Wenbing Tiaobian").

(2) Middle Burner Syndrome

Foot Yangming Stomach Syndrome: fever, thirst, and a large pulse—indicating the need to clear heat and save yin. Treatment includes Baihu Tang and Renshen Baihu Tang. Foot Taiyin Spleen Syndrome: feeling heavy as if wrapped in cloth, body heat not rising, body aches and heaviness, chest tightness and nausea, greasy tongue coating and slow pulse—indicating the need to clear heat and transform dampness. Treatment includes Sanren Tang (from "Wenbing Tiaobian") and Huopu Xialing Tang (from "Wenbing Tiaobian").

(3) Lower Burner Syndrome

Foot Shaoyin Kidney Syndrome: body heat and flushed face, hands and soles of feet much warmer than the backs of the hands, irritability and insomnia, chapped lips and dry mouth—indicating the need to nourish yin and enrich blood. Treatment includes Zhibai Dihuang Tang (from "Zhengyin Maizhi") and Qiju Dihuang Tang. Foot Jueyin Liver Syndrome: deep-seated heat and profound cold, a vague, restless agitation in the heart, trembling of the hands and feet, sometimes even twitching—indicating the need to nourish the liver and calm the wind. Treatment includes Dading Fengzhu and Sanjia Fumai Tang (from "Wenbing Tiaobian").

The Triple Burner Differentiation was created by the warm-disease master Wu Jutong. The upper burner syndrome corresponds to the Taiyang in the Six Meridians and the Wei-level in the Wei-Qi-Ying-Xue system, adding symptoms such as confusion, stiff tongue, and cold limbs caused by heat entering the pericardium, fully reflecting the characteristic of febrile diseases—especially severe acute infectious diseases—that can retrogressively invade the pericardium from the very beginning. The middle burner disease is equivalent to the Yangming in the Six Meridians and the Qi-level in the Wei-Qi-Ying-Xue system, while also incorporating the damp-heat syndrome of the foot Taiyin spleen, thereby supplementing the deficiencies of the Six Meridians and Wei-Qi-Ying-Xue systems and appropriately reflecting the clinical features of gastrointestinal infectious diseases such as typhoid fever and chronic dysentery. The lower burner syndrome corresponds to the Ying-level and Xue-level in the Wei-Qi-Ying-Xue system, while also possessing some characteristics of the Jueyin syndrome in the Six Meridians.

IV. Etiological Differentiation

Traditional Chinese Medicine's understanding of etiology originates from texts such as the "Inner Canon," "Jingui Yaolue," and "Sanyin Fang," broadly categorizing pathogenic factors into three main types: external causes, internal causes, and neither internal nor external causes. Internal causes are also known as the Seven Emotions, while external causes are referred to as the Six Evils. Neither internal nor external causes include dietary factors, overwork, sexual activity, injuries from insects or beasts, or wounds from metal weapons. In modern times, some scholars have summarized these into two categories: internal and external causes.
