A young woman had suffered from epilepsy since childhood, with episodes occurring every few months. The symptoms were mild, and despite treatment, the effects were minimal. In the past two months, the episodes became more frequent, occurring every three to five days, daily, or every other day. During the episodes, she experienced convulsions in her limbs, lost consciousness, foamed at the mouth, and took about fifteen minutes to recover, after which she would fall into a deep sleep. Upon waking, she would feel headaches and dizziness. Recently, she had another episode and urgently sought treatment. Upon examination, she was found lying unconscious on the ground, with her eyes rolled upward, clenched teeth, stiff neck, convulsions in her limbs, and profuse sweating on her head, as if drenched in water, but only up to her neck, with no sweating on her body. There was also phlegm gurgling in her throat. This was due to the binding of phlegm and heat, which surged upward, causing obstruction in the Taiyang (EX-HN5) meridian qi. She was administered 9g of Major Chest Bind Pill. Two hours later, she expelled a large amount of turbid phlegm. Over ten years later, she was seen again and reported that she had never had a recurrence since taking the medication. The "Treatise on Cold Damage Diseases" states: "In cases of thoracic accumulation, the neck becomes stiff, as if flexible, and purgation will restore harmony. Major Chest Bind Pill is appropriate." "However, in cases of thoracic accumulation without significant heat, this is due to water accumulation in the chest and rib area, with only slight sweating on the head. Major Chest Bind Decoction is indicated." When phlegm and heat bind in the chest, pathogenic heat surges upward, causing profuse sweating on the head. The Taiyang (EX-HN5) meridian qi is obstructed by phlegm and heat, leading to a stiff neck and convulsions in the limbs. In Major Chest Bind Pill, Rhubarb Rhizoma, Mirabilite, and Gansui Root purge excess heat and expel phlegm-fluid retention. Pepperweed Seed ventilates the lungs and promotes water metabolism, while Bitter Apricot Seed regulates the rebellious qi in the chest. The pill, with its mild purgative effect, specifically targets phlegm and heat in the lungs and chest. For epilepsy, Major Chest Bind Pill is often used to purge and clear phlegm and heat, followed by spleen-regulating and phlegm-dispelling formulas for further regulation, often yielding excellent results.
