Summary of Internal and External Diseases in Traditional Chinese Medicine
In the ancient medical text of Traditional Chinese Medicine, the section on internal injuries includes six formulas, corresponding to the five elements and the mutual fire.
Dang Gui Sheng Jiang Yang Rou Tang (Angelica and Ginger Lamb Soup) addresses cold hernia abdominal pain caused by Jue Yin Feng Mu (Liver Wind) and Gan Yang Bu Sheng (Liver Yang not rising);
Xie Xin Tang (Drain the Heart Decoction) treats vomiting blood and nosebleeds caused by Shao Yin Jun Huo (Lesser Yin Fire) and Xin Huo Bu Jiang (Heart Fire not descending);
Xiao Jian Zhong Tang (Minor Construct the Middle Decoction) is used for Xiang Huo Bu Jiang (Mutual Fire not descending) causing weakness and urgency in the interior;
Mai Men Dong Tang (Ophiopogon Decoction) addresses dry cough due to Jin Qi Bu Jiang (Metal Qi not descending);
Shen Qi Wan (Kidney Qi Pill, modern formula Gui Fu Di Huang Wan) is indicated for thirst due to insufficient water Qi;
Li Zhong Wan (Regulate the Middle Pill) treats cold diarrhea and vomiting caused by Pi Tu Shi Han (Spleen Earth damp-cold).
The section on external pathogens includes ten formulas.
Among them, the three formulas for Rong Wei Disease include: Gui Zhi Tang (Cinnamon Twig Decoction) to consolidate the Rong Qi (Nutritional Qi) for wind damage, Ma Huang Tang (Ephedra Decoction) to disperse the Wei Qi (Defensive Qi) for cold damage, and Ma Huang Gui Zhi Ge Ban Tang (Half Ma Huang and Cinnamon Twig Decoction) to resolve both Rong Wei injuries with alternating cold and heat.
For internal injuries, there are six meridian formulas and five patterns.
All three Yin meridians correspond to cold syndromes: Zu Tai Yin Pi (Foot Tai Yin Spleen) uses Si Ni Tang (Four Reverse Decoction), Zu Shao Yin Shen (Foot Lesser Yin Kidney) uses Fu Zi Tang (Aconite Decoction), and Zu Jue Yin Gan (Foot Jue Yin Liver) uses Wu Mei Wan (Mume Pill);
All three Yang meridians correspond to heat syndromes: Zu Yang Ming Wei (Foot Yang Ming Stomach) uses Da Cheng Qi Tang (Major Order the Qi Decoction) for excess in the stomach, and Zu Tai Yang Pang Guang (Foot Tai Yang Bladder) uses Tao He Cheng Qi Tang (Peach Pit Decoction) for blood accumulation, causing madness.
Shao Yang is located between the exterior and interior, with only meridian syndromes and no organ syndromes. For alternating cold and heat, lack of desire for food and drink, and irritability with nausea, use Xiao Chai Hu Tang (Minor Bupleurum Decoction). If Shao Yang is combined with Yang Ming organ syndromes, use Da Chai Hu Tang (Major Bupleurum Decoction) to harmonize and open the organs.
Through this summary, one can clearly grasp the characteristics, applicable diseases, and interrelationships of these sixteen formulas, aiding in their accurate application in clinical practice.
