(Note: Opisthotonos)
Xue Lizhai stated: "Chi" (spasm, contraction of tendons and vessels) refers to the tightness and contraction of tendons and vessels; "Zhong" (flaccidity, relaxation of tendons and vessels) refers to the laxity and relaxation of tendons and vessels. The Classics state: The Liver governs the tendons and stores blood. Generally, Liver Qi belongs to Yang and Fire, while Liver Blood belongs to Yin and Water. The aforementioned conditions occur because excessive loss of Yin blood after childbirth leads to blazing Yang Fire, causing the tendons to lack nourishment. Therefore, when pus and water from carbuncles and sores are excessively discharged, or when bleeding from metal wounds is too severe, Yang dissipates along with Yin, often resulting in these conditions. Treatment should employ Bazhen Tang (Eight-Treasure Decoction, a formula for tonifying both Qi and Blood) added with Mudanpi (Cortex Moutan Radicis) and Gouteng (Uncariae Ramulus cum Uncis) to generate Yin blood, whereupon Yang Fire will naturally recede and all symptoms will resolve spontaneously. If there is no response, Sijunzi Tang (Four-Gentlemen Decoction, a basic formula for tonifying Qi) should be used combined with Chuanxiong (Rhizoma Ligustici Chuanxiong), Danggui (Radix Angelicae Sinensis), Mudanpi, and Gouteng to tonify Spleen Earth. Since blood is generated from the Supreme Yin, and the Supreme Yin is Spleen Earth, children who suffer from vomiting and diarrhea subsequently often develop this condition due to Spleen-Stomach deficiency. This is a manifestation of deficiency, with no pathogenic Wind to expel and no Phlegm to eliminate. If it belongs to sinking and collapse of Yang Qi, Buzhong Yiqi Tang (Decoction to Supplement the Middle and Augment the Qi) added with Shengjiang (Zingiberis Rhizoma Recens) and Rougui (Cinnamomi Cortex) should be used; if it belongs to failure of Yang Qi, Shiquan Dabu Tang (Ten-Ingredient Great Tonifying Decoction) added with Rougui and Fuzi (Aconiti Lateralis Radix Praeparata) should be used; some cases may recover. In such syndromes, if there is aversion to cold in the limbs and a faint, fine pulse, this is the true presentation; if the pulse is floating and large, accompanied by fever, restlessness, and thirst, this is a false presentation. One should only focus on consolidating the root as the best approach. If there is weak convulsions, eyes rolling upward (Daiyan), opisthotonos with the body bent backward like a bow, and sweating profusely with beads of sweat flowing, these are all untreatable conditions. There is also opisthotonos, caused by Wind pathogen entering the Yang meridians through deficiency, leading to backward bending of the waist and back, with spasms and stiffness resembling the shape of a horned bow. All these result from depletion of Qi and Blood, loose interstices (Couli), and excessive sweating. The primary treatment should be to consolidate Qi and Blood, assisted by the aforementioned formulas. As Zhu Danxi said, postpartum treatment should primarily focus on greatly tonifying Qi and Blood; even if other miscellaneous disease patterns exist, they should be treated as secondary concerns. If there are symptoms such as aversion to cold and fever, this indicates extreme depletion of Qi and Blood, and large doses of Renshen (Ginseng Radix et Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma), Danggui, Baizhu, and Rougui should be used to cultivate the body. If there is no response, Pao Fuzi (Prepared Aconite Root) should be urgently administered. If still ineffective, use one liang of Renshen and two to three qian of Pao Fuzi, named Shenfu Tang (Ginseng and Aconite Decoction). If there is still no response, it is because the medicinal power has not yet reached the disease site; the dosage should be increased and continued.
