Huang (5 fen. If the condition is severe, or if there is significant heat due to overwork and fatigue, use 1 qian.) Danggui Shen (2 qian. Baked with wine or dried in the sun, to harmonize the blood vessels.) Renshen (3 qian, remove the rhizome. If cough is present, do not use.) Baizhu (3 fen, to tonify Middle Qi. ○ Xue Shi Yi An uses 1.5 qian.) Chaihu (2 fen, to guide clear Qi upward, acting on the Shaoyang meridian.) Zhi Gancao (5 fen) Shengma (2 fen, to guide Stomach Qi upward and restore its original position; this constitutes the execution of the Spring ascending command.) Chenpi (3 fen, to direct stagnant Qi, and can also benefit Yuan Qi. It must be used with various sweet herbs. If used alone, it drains Stomach Qi.)
The above ingredients are cut into small pieces, combined as one dose. Add two zhan of water, decoct until one zhan remains, remove the dregs. Take warm when very hot, far from meals. ○ Xue Shi Yi An notes: add fresh ginger and jujube, take on an empty stomach before noon.
Hu comments: The above formula originally treats conditions such as internal injury fever caused by improper diet and fatigue. However, Danxi used it to treat Zhonghan (Cold Stroke), reasoning that Shanghan (Cold Damage) often involves excess-heat, suitable for purging, whereas Zhonghan often involves deficiency-cold, suitable for tonifying. Thus, the above formula was used with added dispersing herbs. I believe that for Zhonghan caused by external cold invasion, tonification combined with dispersion is indeed appropriate. However, for cases caused by ingesting cold substances, warming the Middle and promoting digestion are still necessary. The use of the above formula may be overly tonifying. Its application depends entirely on the physician's flexible modification based on clinical presentation.
Dai Yuanshi stated: In Zhonghan syndrome, the body becomes stiff and rigid, the mouth is locked and speechless, or there is trembling of the four limbs, or shivering aversion to cold, or slight fever, or sudden vertigo, with no sweat on the body. This indicates being struck by Cold Toxin. Initially, Suhe Xiang Wan should be taken mixed with wine. For mild cases, Wuji San is administered, adding 1 qian of Xiangfu and a small amount of Shexiang. For severe cases, Jiang Fu Tang is used. If the patient gradually revives, the body warms up, and speech returns slightly, after a moment, inquire about other symptoms. If accompanied by Qi attack causing stabbing pain, add Ban qian of Muxiang to Jiang Fu Tang. If accompanied by Wind causing numbness, add 1 qian of Fangfeng. If accompanied by Dampness causing swelling and pain, add 1 qian of Baizhu. If tendons and vessels are pulled tight, add 1 qian of Mugua. If limb joints are painful, add 2 qian of Guizhi.
