Senkyu-chacho-san (SC), an herbal medicine, can modulate striatal dopamine levels, but its effects on Parkinson's disease (PD) are unclear. To evaluate the efficacy, tolerance, and safety of SC in PD, 22 patients with idiopathic PD (aged 49 to 82 years; 13 women, staging Hoehen and Yahr 3 or 4) were given SC, 5.0 or 7.5g three times per day, for eight weeks. Existing antiparkinsonian drug regimes were kept unchanged. Motor functions were assessed based on the Unified Parkinson's Disease Rating Scale (UPDRS) at baseline and at weeks four and eight. After four weeks of SC administration, 14 patients showed a significant improvement in motor performance with respect to the motor scores of the UPDRS (p<0.05). The improvement in motor function declined slightly in four patients after eight weeks of treatment. No patients became worse in motor functions during treatment, and no serious adverse events occurred. This study suggests that SC is useful as an adjunct to dopaminergic drugs in PD.

Background: Kampo medicine is the traditional form of medicine practiced in Japan, based on ancient Chinese medicine. Kampo medicine includes acupuncture and moxibustion, as well as herbal medicine. Physicians are allowed to prescribe ethical Kampo extract granules used in various formulae and practice acupuncture and moxibustion as acupuncturists and moxibustionists. However, medical schools do not offer many classes in traditional medicine. This study aims to analyze the use of Kampo formulae and practice of acupuncture and moxibustion in contemporary community health care.
Methods: The subjects (1538 clinicians) were graduates of Jichi Medical University on or after 1978, affiliated with a clinic or hospital with 300 beds or less on July 2010, and surveyed by postal questionnaire in October 2010.
Results: The effective response rate across Japan was 44% (n=679). Of these responders, 30%, 45%, and 22% were found to prescribe Kampo formulae regularly, occasionally, and rarely, respectively, in daily clinical care. Frequently prescribed formulae included shakuyakukanzoto, daikenchuto, kakkonto, rikkunshito, and hochuekkito. The reasons for using Kampo formulae given by 61% and 58% of the responders were, respectively, applicability for common diseases and ease of use for unidentified complaints and psychosomatic disease. Among the reasons for unlikely use, unclear applicability was chosen by 34% of the responders; difficulty stocking many formulations by 33%; and insufficient evidence of efficacy by 30%. Practitioners of acupuncture and moxibustion accounted for 4% of the responders. The main indications for acupuncture and moxibustion included low back pain and shoulder stiffness.
Conclusions: A large number of primary care physicians use Kampo formulae, implying their usefulness. However, one out of three physicians complains of unclear applicability and insufficient evidence of efficacy for Kampo formulae. In the future, appropriate education and research will be needed to clarify these issues.

Here, we report a case of nocturnal enuresis persisting into adulthood treated with Kampo medicine. A 21-year-old woman had a history of nocturnal enuresis every night during childhood and once every 2-3 nights during school age. Although the frequency of urinary incontinence decreased to 1-2 times/week at 19 years of age, nocturnal enuresis persisted into adulthood. She was diagnosed with mild strain of the rectus abdominis muscles and palpable abdominal aortic pulsation above the umbilicus, and keishikaryukotsuboreito (decoction) therapy was initiated. She did not experience urinary incontinence at night for 3 weeks, except for one episode immediately after treatment commencement. She tended to urinate only 4 times from the time she awoke until bedtime ; therefore, we added a small amount of goreisan to her treatment regimen to increase the urinary output and daytime frequency of urination. The frequency of urination increased from 4 to 7 times and stabilized. We discontinued goreisan administration 2 months later, and keishikaryukotsuboreito monotherapy was continued. We did not observe recurrent nocturnal enuresis and, therefore, switched the decoction to an extract. After the symptom stabilized, the dosage of keishikaryukotsuboreito was reduced by half. Nocturnal enuresis occurred only once when the patient missed a dose for 3 consecutive days but did not recur for over 4 months after strict adherence to medication. This case report highlights the role of Kampo therapy as an effective therapeutic option for nocturnal enuresis persisting into adulthood.
