Consideration on Adaptive Condition of Soshikokito / 日本東洋医学雑誌

Soshikokito has long been used to treat cough in frail patients with cold sensation in their feet, based on the Japanese traditional Kampo textbook “Iryo-Shuhou-Kiku”. In many old documents including “Wazai-Kyokuho,” where soshikokito was first described, it is suggested that airways obstructed by a large quantity of watery expectoration should be the proper indication for the use of this formula. However, in the five cases that we successfully treated, the quantity of sputum was relatively small. To determine the practical indications for this, we examined their abdominal strength and the presence or absence of “cold feet” sensation. In addition, we investigated the nature of sputum in the past clinical reports in which successful treatment using soshikokito was described. It has become clear that we can prescribe soshikokito as an antitussive regardless of the patients' physical fitness as deduced from the abdominal strength. The “cold feet” sensation was not an essential symptom and was regarded as one of the symptoms of qi counterflow. Regarding the properties of sputum, it was viscous and small in quantity. In the cases where soshikokito was effective, it was speculated that viscous sputum would result in airway obstruction, coughing, and wheezing. These conditions will be ameliorated by the antitussive and expectorant effect of this formula, which improves qi counterflow and mildly tonifies water. In the treatment of cough with respiratory distress, “sputum with high viscosity and hard to discharge” is considered to be the targeted symptom in the practical usage of soshikokito.

Two Cases of Prolonged Tinnitus Successfully Treated with Soshikokito / 日本東洋医学雑誌

Soshikokito is a Kampo formulation used in the treatment of bronchial asthma, especially in those patients with hot flushes and cold sensation in their feet. But there is also a description in classical textbooks for its usage for the treatment of tinnitus. We report two typical cases of prolonged tinnitus treated successfully with soshikokito. Case1was a 70-year-old woman who visited our clinic complaining of tinnitus, dizziness and insomnia. She had a history of bilateral otitis media in her childhood, and had been suffering from tinnitus after being operated for it. The tinnitus had worsened during the three months prior to her first visit to us. After 3 months' treatment with soshikokito with additional shisoyo, her symptoms improved, so much so that after 8 months, she could live her life normally. Case 2 was a 58-year-old man who presented with tinnitus, hearing disturbance and a sense of irritation. He also complained of insomnia and cold sensation in his limbs. After1month's treatment with soshikokito with additional shisoyo and bushi, most all of his symptoms resolved. In addition, we also evaluated the clinical efficacy of soshikokito for prolonged tinnitus, retrospectively, and found that it was effective in five out of the ten cases we treated with this formulation. Most of the successfully treated patients presented with hot flushes or cold sensation in their feet. These case reports suggest that soshikokito may be a useful formulation for the treatment of not only bronchial asthma, but also of prolonged tinnitus.

A Case of Jugular Sense of Discomfort with Dryness and Nonproductive Cough Successfully Treated with Soshikokito / 日本東洋医学雑誌

We report a case with an intractable jugular sense of discomfort, with dryness and nonproductive cough successfully treated with soshikokito. A 62-year-old Japanese man developed jugular sense of discomfort with dryness and nonproductive cough, after odontotherapy in October. Although he was treated with Western drugs by an otolaryngologist, under the diagnosis of xerostomia with no mechanical problems, his symptoms did not disappear. The symptoms followed a protracted course, and he further developed a loss of appetite. At the time of first visit in October, otorhinolaryngological studies showed no structural lesions or problems, with the exception of minimum salivation in the normal range on a gum test. There was no evidence of dry eyes. With the diagnosis of xerostomia, Bakumondoto-go-hangekobokuto was administered for a month but showed no sign of improvement. Making a shift to bukuryoin-go-hangekobokuto regained his appetite, but did not produce any improvement on dryness. We then utilized soshikokito under the interpretation that both dryness and nonproductive cough is ki-gyaku. The soshikokito therapy reduced his dryness in a month's time. Additionally, his nonproductive cough gradually decreased, and within 11 months after, he had no symptoms, regardless of a gradual medication withdrawal.
