We investigated the decocting time to prepare the formulas containing unprocessed aconite root, such as shigyakuto, tsumyaku shigyakuto, and kankyobushito, which had been registered in “Shanghanlun” edited in Song Dynasty, using the weights and measures in Houhan Dynasty when the original “Shanghanlun” was regarded to have been established. Also the contents of aconitine-type diester alkaloids (ADA) eluted from unprocessed aconite root in the decoction were analyzed in time-dependent manners. As regards the modified formula for the “physically strong patients” in the texts of tsumyakushigyakuto in “Shanghanlun”, adding dried ginger was found to lead the decocting time to be shorter and the sum of ADA content in the decoction of the modified formula to increase about 20%. It was also found that the compositions of diterpene alkaloids derived from aconite root in kankyobushito decoction were highly different from those in shigyakuto decoction, containing less ADA and more aconine and hypaconine, due to the high pH of the decoction, which was the consequence of lacking glycyrrhiza in kankyobushito formula. It is suggested that the doctors in the era of “Shanghanlun” establishment may have carefully adjusted the contents of ADA in the decoctions using unprocessed aconite root by choosing co-decocted crude drugs.

We examined 57 patients treated with Kampo decoctions containing uzu for 5 years and 3 months from September 2013. Sekiganryo, which was administered to 32 patients, was the most commonly used decoction. The value of uzu dosage and duration of administration were spread widely and the medians (ranges) are 8.0 (1.0-41.0)g/day and 180 (3-1700) days, respectively. Complete recovery, partial recovery, no recovery, and deterioration in terms of the chief complaint, were observed in 36, 11, 9, and 1 patients, respectively. The number of patients exhibiting complete or partial recovery was higher than that of patients showing no recovery or deterioration when the duration of uzu administration was more than one month and the dosage was higher than 4 g/day (p < 0.05). The patients treated with uzu more than 20 g/day were all sekiganryo administrated ones. Side effects were observed in three patients. Thus, under careful observation, uzu was safely used over a long term and at high doses.

Shomakakkonto is usually used for the treatment in patients with initial cold or dermatitis symptoms. We herein reported our experience with two cases of common cold accompanied by watery eyes and floating pulse that were successfully treated with shomakakkonto. The patients were an 81-year-old man and a 69-year-old woman who presented with common cold-like symptoms and watery eyes at our clinic, and were diagnosed with common cold of middle yang. Both patients were successfully treated with shomakakkonto. Common cold with watery eyes may be considered as an indication for treatment with shomakakkonto.

Thalamic pain is an intractable central pain caused by thalamic hemorrhage and infarction. Unfortunately, there is no established method for its treatment. We report five cases of thalamic pain effectively treated with keishikaryukotsuboreito. Case 1 was a 63-year-old man who complained of pain in the right side of his body for three years after thalamic infarction. Case 2 was a 68-year-old-man who complained of pain in the right side of his body for 13 years after left thalamic hemorrhage. Case 3 was a 74-year-old woman who complained of left limb pain for three years after right thalamic hemorrhage. Case 4 was a 67-year-old woman who complained of pain in the upper and lower right limbs for two years after right thalamic infarction. Case 5 was an 82-year-old man who complained of pain in the right lower limb for two months after left putaminal hemorrhage including left thalamus. All cases were treated with keishikaryukotsuboreito and their symptoms improved. However, in Case 5, thalamic pain recurred after three months and the effect was not sustained with keishikaryukotsuboreito alone, but it was effective when combined with keishibukuryogan. From the imaging findings, keishikaryukotsuboreito would be a useful option for the treatment of thalamic pain with localized lateral thalamic lesions.

In the treatment of climacteric disorders, evaluation of menopausal women based on personal and overall aspects of their sho condition has been found to be useful. This form of treatment is considered particularly useful for patients who cannot, or do not wish to use hormone replacement therapy (HRT). In this paper, we present the cases of patients who were assessed using sho and the Kampo medical index, and given successful treatment using kuoketsuzai (drugs for overcoming oketsu) and yokukansankachinpihange.

Few reports currently exist demonstrating that Kampo medicine is effective for dry nose. Here, we describe three cases of dry nose that were successfully treated with hachimijiogan or rokumigan. The chief complaints of the three cases differed. Dry nose was the second or third most troublesome symptom. The three cases had kidney deficiency and its typical symptom of abdominal numbness in common. Upon administration of hachimijiogan or rokumigan, dry nose improved promptly, along with the improvement of kidney deficiency. In addition, it became easier for all three cases to breathe. According to “Pu ji fang”, dry nose is ascribed to wind-­heat or kidney deficiency. The kidney is considered to control the reception of qi inhaled by the lungs. Taken together, we speculate that dry nose of the three cases were due to kidney deficiency, because treatment with hachimijiogan or rokumigan improved their dry nose along with the improvement of their kidney defi­ciency as well as their breathing which suggests the improvement of the reception of qi inhaled by the lungs. Hachimijiogan or rokumigan is shown to be effective for dry nose in the patients with kidney deficiency.

We report the case of a 36-year-old male who presented with an abdominal complaint after straightening of irregular teeth. He was examined and treated, however, the cause of the abdominal complaint could not be determined and the treatment was ineffective. He was treated in our clinic with yokukansankachinpihange for obvious pulsation in the supraumbilical region following the oral tradition of Kampo medicine, and the symptom gradually disappeared. We discussed the mechanism of the stomachache in Kampo medicine. After treatment, this case was diagnosed as somatoform autonomic dysfunction in psychiatric medicine. Advanced treatment by a psychiatrist was necessary to treat this disease in psychiatric medicine. In this case it is suggested that treatment following the oral tradition of Kampo medicine was effective.

We administered Japanese Kampo medicine for seven patients with Grade 3 or more idiopathic sensorineural hearing loss who could not be administered enough amounts of steroids for some reasons. They all exhibited deficiency patterns, and which were all dual deficiency patterns of qi and yin. All patients were administered hochuekkito and hachimijiogan. Six patients were cured, and one patient was recovered.

Using the data of 139 ovarian cancer cases at our hospital, we investigated the effect of jingizai on prognosis when it was combined with standard therapy for ovarian cancer and prognosis by histopathological types. Combining jingizai with standard therapy was not effective in cases of stage I-II ovarian cancer, but it was effective in cases of stage III-IV ovarian cancer. Upon examination the effectiveness of jingizai according to histopathological types, we observed some improved prognosis in serous adenocarcinoma and mucinous adenocarcinoma cases ; however, prognosis didn't improve in endometrioid adenocarcinoma and clear cell adenocarcinoma. These results indicate that the effectiveness of combining jingizai with standard therapy may differ depending on histological type of ovarian cancer. When we investigated the difference between the distribution of histopathological types by cancer staging, we frequently found clear cell adenocarcinoma in stage I-II cancer cases. Also, serous adenocarcinoma and poorly differentiated adenocarcinoma had a high frequency among stage III-IV cancer cases. This difference may be the reason that the effectiveness of jingizai is different depending on the advances of each stage. However, no statistical difference was confirmed due to the small number of subjects analyzed. Analysis of larger sample size, which can be collected by performing collaborative studies with other facilities, will be required for more detailed investigation.

A female with persistent emesis after eating was successfully treated with nichinto, although neither various western-style medicines nor Chinese herbal medicines including rikkunshito or shohangekabukuryoto were effective. Considering the constituent crude drugs, we believe riki (moving of qi) medicine is potent against vomiting associated with psychological factors, while hoki (rising of qi) medicine would be extra crude drug in the absence of hikyo (deficiency of digestive function).

Vulvodynia is defined as vulvar pain of at least three months duration without a clearly identifiable cause. Currently, there are few established treatments. We report two cases of vulvodynia treated successfully with relief of insomnia, using Japanese herbal medicine including saiko. Case 1: A 29-year-old female had been in a poor physical condition for two years. Initially, she had vulvar itching, which gradually became vulvar pain. At the first consultation, she complained of not only vulvar pain but also insomnia and feeling cold. Additional symptoms included severe fatigue, constipation, frustration, stiff shoulder, and heart palpitations. There were no abnormal findings in the genital region. We began treating the insomnia and coldness using saikokeishikankyoto. By the time of the second consultation two weeks later, her insomnia and coldness completely resolved, vulvar pain disappeared, and other symptoms improved. Case 2: A 46-year-old female experienced vulvar pain two months before the first visit to the hospital. The pain increased gradually and she awakened every 30 minutes in the night with severe vulvar pain. However, there were no abnormal findings in the genital region. We used saikokaryukotsuboreito, an antidepressant and a sleeping pill. Her insomnia improved gradually, and vulvodynia resolved two weeks after the improvement of the insomnia. These results suggest that saiko is effective on vulvodynia with insomnia.

The treatment by Kampo decoction is partly covered by National Health Insurance in Japan. However, this system is facing bankruptcy crisis because of rising prices of crude drugs in China, their main producer. The board of crude drug materials of the Japan Society for Oriental Medicine (JSOM) distributed questionnaires to 7416 JSOM member doctors, and performed statistical analysis (with JSOM approval) of 1877 answers to visualize the data. Twenty-six percent of respondents said that they had prescribed a decoction, and 29% of respondents said they had not, but wanted to prescribe a crude drug. Eighty-eight percent of doctors who prescribe decoctions offered medical treatment primarily to insured patients. Nine percent offered medical treatment at patients' own expense. The latter group prescribed decoctions more frequently. Many doctors were aware of the financial risk of prescribing crude drugs imposed by the drug price standard and rising crude drug import prices. Four hundred and fifty­-five doctors explained when they were most inclined to prescribe a decoction. Thirty-five percent of these said they used decoctions when they couldn't treat patients with extracts. This result implies a necessity for decoctions. Many doctors said they prescribed decoctions for autoimmune or allergic diseases. Financial constraints were the most frequently cited barrier to treatment with decoctions. This survey made clear the financial difficulties clinics are facing. We therefore calculated the amount of crude drugs used for decoctions to validate the possibility of their domestic production.

We examined 375 patients who were administered Kampo medicine for emergency hospitalization in the acute period ward for 6 years and to improve early illness and symptoms. There were many significant uses of hozai. Of the top 5 types of Kampo medicine administered, 4 were hochuekkito, ninjinyoeito, rikkunshito, and daikenchuto. In the case of emergency hospital admission, it was considered that there were many uses of hozai for poor oral intake, walking disorder, and low level of consciousness, among others. Next, there were many risuizai uses.

The authors previously reported on a Dr. Todo Yoshimasu's visit to a feudal lord of Nambu domain in 1752. This paper describes the outcomes of our investigation on what happened after the visit based on the diary “Zassyo” written by a chief retainer of the domain. Despite Yoshimasu's treatment, the load was not cured and ended up passing away. At that time, there were three of Yoshimasu's pupils who were from Nambu and serving as medical doctors for the domain. A record in the diary indicates that, after the lord's death, all of them were either discharged or penalized with pay cut. It indicates that Yoshimasu's revolutionary medical philosophy and methodology were not fully understood nor appreciated back then.

The Japan Society for Oriental Medicine has summarized randomized controlled trials (RCTs) using Japanese traditional (Kampo) medicine in structured abstracts, named “Evidence Reports of Kampo Treatment” (EKAT). In this study, we developed a method of classification based on study design, method of intervention, study aim, journal credibility, and year of publication. Then we classified 416 RCTs in EKAT and examined the current status and evolution of RCTs using Kampo medicine in Japan. Double-­blinded RCTs (DB-RCTs) accounted for only 8.9% of the RCTs in EKAT, and 86.5% of DB-RCTs were placebo-controlled. Among the RCTs that aimed to investigate the efficacy of Kampo medicine for diseases without standard Western medical treatment, DB-­RCT accounted for 64.9%. In recent years, there have been fewer envelope RCTs and quasi-­RCTs, which are prone to an increased risk of bias. The proportion of articles reporting RCTs in journals with an impact factor ( > 0.79 points reported by Journal Citation Reports) has been increasing with each passing year. This implies that the recent research in Kampo medicine has improved its quality and has gained an appreciation in modern medicine. The present study was conducted in “Problem-based Learning” in the 2nd grade of Tohoku University School of Medicine.
