Introduction : We evaluated the efficacy of keishito and maobushisaishinto with reference to keikyososooshinbuto, for patients feeling cold, by means of multiple regression analysis.Case reports : We reported a patient with an upset stomach whose severe coldness was improved as the stomach condition was cured by adding keishito to maobushisaishinto. Moreover, the combination of keishito and maobushisaishinto was effective for a patient feeling cold, with appetite loss, general fatigue and stiffness of the joints (case 1), a patient feeling cold, with chill, general fatigue, heavy feeling in the stomach, and prone to catch colds (case 2), and a patient feeling extremely cold, with general fatigue and menstrual pain (case 3).Subjects and Methods : In this study, the subjects were 43 patients who reported feeling cold. They were treated with keishito and maobushisaishinto according to their Sho for more than one month. The relationships between the improvement of cold sensation and 52 other factors, such as symptoms noted at their first medical examination, were evaluated by means of multi-dimensional cross-sectional analysis. Results : The factors of chilly or unpleasant wind and coldness of the whole body were significant. Discussion : The factors of coldness in the whole body with chill, and headache without diarrhea were important for improvement of cold feeling with keishito and maobushisaishinto.

It is important to treat patients with spleen qi deficiency not only with formulations for their deficiency, but also with formulations to improve qi stagnation. Rikkunshito plus Cyperi Rhizoma, Amomi Semen and Agastache rugosa, which improve qi circulation, was effective in cases 1 and 2 herein. We examined when and how to prescribe kososan with formulations for spleen qi deficiency, with reference to kosharikkunshito. Kososan and rikkunshito were effective in cases 3 and 4. Based on rikkunshito indication, a patient with weaker constitution was prescribed shikunshito (case 8), a patient with diarrhea and vertigo was prescribed shinbuto (cases 5 and 6), and a patient with severe coldness was prescribed ninjinto (case 7). Kososan played a supplementary role in treatment, and can be prescribed with other medicines. Not only gastrointestinal symptoms, but also various other complaints were improved by adding kososan to prescriptions for spleen qi deficiency.

Teian Azai classically described that summer heat was caused by humidity in addition to hot weather. It may occur after becoming chilled while asleep, enjoying the evening cool, and taking cold foods and drinks. Humidity and high temperature prevent qi circulation in the stomach. Therefore, he insisted that goreisan, a formula improving water circulation, could be applied for diverse symptoms caused by summer heat. We present two cases of patients with epigastralgia caused by cold foods and drinks in air-conditioned environments, whose symptoms were improved by goreisan. In prior treatment, anchusan in case1, and rikkunshito in case 2 were not effective for their epigastralgia. Nineteen cases of epigastralgia after taking cold foods and drinks in summer, including these two cases, revealed that goreisan was efficacious against summer epigastralgia with white fur on the tongue and a stuck feeling in the pit of the stomach. Abdominal fluid congestion is a major abdominal sign for an indication of goreisan, but a stuck feeling in the pit of the stomach presented in some effective cases with goreisan. We concluded that epigastralgia caused by cold foods and drinks with white fur on the tongue and a stuck feeling in the pit of the stomach could be a target for the application for goreisan.

We report on five patients with menstrual pain and/or other disorders, whose symptoms improved when treated with Ki-related prescriptions. Hangekobokuto improved severe epigastralgia and menstrual pain in Case 1. Saibokuto showed improvement of menstrual disorders and pain in Case 2, while Hangekobokuto also ameliorated menstrual pain in Case 3. The treatments were based on patient Ki stagnation, although the symptoms of Ketsu stagnation were also observed in these cases. In Case 4, the patient's menstrual pain and disorders were improved by changing her prescription from Kamishoyosan, to Keishikaryukotsuboreito. In Case 5, a menstrual period of more than 40 days became a regular rhythm of 30 days, while treating the patient's chief complaint of urticaria, with Keishikaryukotsuboreito. Symptoms of Ketsu stagnation were not apparent in Cases 4 and 5. We prescribed Keishikaryukotsuboreito—a prescription for Ki regurgitation—because of suggestive symptoms of nightmare, as well as palpitation in the abdomen.
Menstrual problems are often related to Ketsu abnormalities according to Kampo medicine literature. However, symptoms related to Ki regurgitation and Ki stagnation are also observed in women with menstrual problems who are under stress. Therefore, it is important to know that there have been cases, such as ours, of menstrual problems successfully treated with Ki-related prescriptions.

We describe three cases in which the same Kampo formulas were applied to a mother and daughter with different complaints. In cases 1 a, b, a mother with general fatigue after an operation for gastric and colon cancer, and her daughter with migraine and menopausal symptoms were effectively treated with kamishoyosan. In cases 2 a, b, a mother with menstrual disorder, and her daughter with palmar eruption were effectively treated with hangekobokuto. In cases 3 a, b, a mother with lumbago and her daughter with back pain were effectively treated with keishikaryukotsuboreito. These Kampo formulas are thought to improve qi circulation.
It is considered that improving qi disturbance is important for the Kampo treatment of female patients. Taking into account parent-child genetic similarities, it is possible that application of the same Kampo formula to familiarly related patients with different complaints could be effective. It is important to consider not only the patient's complaints, but also the patient's condition, from the Kampo viewpoint so-called “Sho”. Therefore,since our cases all involved a mother-daughter relationships, it may be reasonable to assume that Kampo formulas improving qi circulation were effective for their different complaints.

We would like to report on the treatment of 15 patients with floating sensation after the Great East Japan Earthquake (2011 Tohoku Earthquake) in 2011.Twelve cases were effectively treated with hangekobokuto, while two cases were effectively treated with hangebyakujutsutemmato, but not with hangekobokuto.One case was effectively treated with ryokeijutsukanto. We discuss how to treat this floating sensation, focusing on the usage of hangekobokuto.
Most patients who were successfully treated with hangekobokuto reported an uneasy feeling with a floating sensation. On the other hand, those who were successfully treated with hangebyakujutsutemmato or ryokeijutsukanto did not feel uneasy, but reported vertigo and upset stomach.Upon abdominal examination, epigastric resistance was frequently observed in the patients treated with hangekobokuto.This resistance decreased as the floating sensation was improved.
Our results indicate that hangekobokuto could be efficacious for patients with floating sensation after an earthquake, who also felt uneasy and showed epigastric resistance upon abdominal examination.

The effect of Kampo therapy (Japanese traditional herbal medicine) on the second derivative of the photoplethysmogram (SDPTG) was investigated. The SDPTG is the second derivative of the fingertip photoplethysmogram (PTG), which expresses the characteristics of the vascular system, the properties of peripheral vessels, and the state of blood flow. The subjects comprised 13 normal volunteers, 101 patients (21 males and 80 females; mean age 53±11 years) with 1 month of Kampo therapy, and 19 patients (4 males and 15 females; mean age 60±9 years) with 3 months of medication. Control subjects showed no significant changes in their vascular age after 1 month. Patients with a higher vascular age than expected before therapy showed improvement of their vascular age, after treatment for 1 month and 3 months. The difference between the vascular age and calendar age decreased from about 10 to 7 years after 1 month of therapy (n=65. p<0.001), and from about 9 to 4 years, after 3 months (n=11, p<0.01). Vascular age not only reflects organic vessel wall sclerosis due to arteriosclerosis, but also a vascular wall tone that is closely related to the autonomic nervous system. The change of vascular age within a relatively short period suggested a functional change rather than an organic change of the vessels.

Tokito is used to treat patients with an asthenic, cold constitution, who have symptoms of chronic pleuritic pain, epigastralgia, and backache. There is no previous report on treatment of pruritus cutaneus with tokito. However, here we report a case of combined cutaneus pruritus and coldness, successfully treated with tokito. Our patient was a 38-year-old female, who reported having had facial pruritus cutaneus for one year. She attended our clinic in May of the year, because she had taken a turn for the worse. She was sensitive to cold, had poor circulation, felt cold in the abdomen, and reported that sleeping was difficult due to a cold back. We prescribed tokito (5.0 g/day). Her symptoms improved within six days. However, her symptoms, especially cold abdomen and cold back, returned when she drank cold water or stopped taking tokito. She was quite informative in that she prepared detailed records of her symptoms on visiting our clinic.
Tokito contains herbal medicines common to daikenchuto and tokikenchuto and hangekobokuto. Therefore, tokito could be a suitable herbal medicine for patients with pruritus cutaneus caused by coldness and qi stagnation and spleen deficiency.

In Kampo, respiratory symptoms are treated with prescriptions related not only to “lung”, but also other parenchymatous viscera. We report 2 patients whose stress-induced chronic cough was ameliorated by hachimijiogan. Case 1 was a 25-year-old female who was working under stressful circumstances at her company and reported an oppressive feeling in the chest. She was initially prescribed hangekobokuto because of a feeling that something was stuck in the pit of her stomach on abdominal examination, but her cough did not get better. As she also noted a dull feeling in her back ; she was switched to hachimigan, and her cough disappeared. Case 2 was 42-year-old female who suffered from depression, sore throat and an obstructive feeling in the throat ; she had been receiving infertility treatment for several years. Hangekobokuto and bakumondoto showed insufficient effect on her persistent cough. Her coughing stopped when she was prescribed hachimigan for back pain. Neither of these patients showed lack of resistance of the lower abdomen on abdominal examination.
Chronic ki (qi) stagnation under stressful conditions may cause ki deficiency, especially kidney deficiency. The symptom of stress-induced cough in our cases was considered to be due to kidney deficiency, and therefore hachimijiogan, but not hangekobokuto, was effective. The short duration of the complaints and relatively young age (20-40's) of the patients may account for the absence of the typical abdominal sign of kidney deficiency. Back stiffness and pain may also be important signs for cough due to kidney deficiency.

We present a 35-year-old male with palpebral hemispasm, which often occurred while at work. Because there were no ophthalmological findings, he consulted our clinic to receive Kampo therapy. He easily became fatigued and he had subchondral resistance and discomfort (kyo-kyo-kuman), so we treated him with saikokeishito and shakuyakukanzoto. However, they were ineffective, and therefore we reconsidered his symptoms.
Although he complained of fatigue, he was well built and had been a heavy drinker until a few years before presenting. Furthermore, he easily blushed and sweated in the upper body during the daytime, and his palpebral hemispasm often occurred during this blushing and sweating, and was accompanied by headache. We considered that this represented an excess-heat pattern rather than a deficiency pattern, and prescribed orengedokuto. His symptoms improved, and disappeared after six months.
There has been no detailed report of orengedokuto for the treatment of palpebral hemispasm. Orengedokuto may be useful for palpebral hemispasm in the context of symptoms of excess-heat pattern, such as blushing, sweating in the upper body and headache.
