We investigated the influences of hot-spring bathing on the incidences of abortion and premature birth using questionnaires returned from 768 puerperal in-patients.
These patients were classified into four groups: 24 taking a hot-spring bath daily (group 1), 134 taking a bath with additives (group 2), 178 taking a plain water bath daily (group 3), and 35 taking a shower daily (group 4).
The incidence of threatened abortion among the ambulatory patients in each group was 4.2% for group 1, 11.9% for group 2, 9% for group 3, and 2.9% for group 4.
The incidence of threatened abortion among the hospitalized patients in each group was 4.2% for group 1, 6.7% for group 2, 4.5% for group 3, and 8.6% for group 4.
The incidence of threatened premature birth among the ambulatory patients in each group was 12.5% for group 1, 17.2% for group 2, 15.7% for group 3, and 14.3% for group 4.
The incidence of threatened premature birth among the hospitalized patients in each group was 0% for group 1, 7.5% for group 2, 3.4% for group 3, and 2.9% for group 4.
The incidence of vaginitis among the patients in each group was 50% for group 1, 43.4% for group 2, 46.6% for group 3, and 44.1% for group 4.
The incidence of premature rupture of membrane (PROM) among the patients in each group was 4.2% for group 1, 21.1% for group 2, 12.9% for group 3, and 22.9% for group 4.
The incidence of premature birth among the patients in each group was 0% for group 1, 3% for group 2, 2.8% for group 3, and 2.9% for group 4.
Among the 42 multiparas experiencing single delivery and being treated for threatened abortion, those who for more than 10 minutes daily showed a significant difference from ambulatory patients being treated for threatened abortion that required hospitalization.
Many of the 63 primiparas who did not use a labor accelerating medicine but bathed for more than 10 minutes daily delivered their babies within 1000 minutes.
Conclusion
The above suggests that pregnant women may bathe in hot-springs without problem but bathing for less than 10 minutes is recommended during early stage of pregnancy.

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.
