Ephedra is the key herb for Dingchuan (EX-B1), and I believe there is no need to worry about its diaphoretic effect. The "Treatise on Cold Damage Diseases" states: "After inducing sweating, one should not administer Cinnamon Twig Decoction again. If there is sweating and panting without high fever, Ephedra, Bitter Apricot Seed, Gypsum, and Licorice Decoction can be given." "After purging, one should not administer Cinnamon Twig Decoction again. If there is sweating and panting without high fever, Ephedra, Bitter Apricot Seed, Gypsum, and Licorice Decoction can be given." In the above two passages, Zhongdu (LR6) mentions "sweating and panting." Since Ephedra can be used for conditions involving sweating, it is evident that Ephedra itself does not induce sweating. Based on the author's clinical experience, it also does not cause sweating. The dosage for infants is 0.9g to 1.5g, and for children, 1.8g to 3g.

Raw Gypsum clears heat, releases flesh, and reduces fever, making it an excellent remedy for pneumonia. Some people consider Gypsum to be extremely cold (Great Cold, 24th solar term) and are overly cautious about it. According to the "Shennong Bencao Jing," "Gypsum has a pungent taste and is slightly cold," not extremely cold (Great Cold, 24th solar term). Later commentators exaggerated its cold nature, which is somewhat overstated. Yu Shi-yu's "Yizhen Yide," Jiang Bihua's "Bihua Yijing," and Zhang Xi-chun's "Yixue Zhongzhong Canxilu" all advocate the use of large doses of Gypsum for general febrile sexually transmitted diseases. This indicates that raw Gypsum has a mild nature and can be used for febrile sexually transmitted diseases, as the author has also observed in clinical practice. However, due to its descending nature, it should be used cautiously in children with diarrhea.
