Effectiveness of Makyoyokukanto Combined with Powdered Cinnamon bark and Processed Aconite Root for Chronic Sciatica / 日本東洋医学雑誌

Chronic sciatica is one of the neuropathic pains which assumed to be effective for pregabalin. However, a recent double-blind placebo-controlled trial reported that pregabalin was no more effective than placebo in patients with acute or chronic sciatica. We retrospectively investigated the effect of Kampo medicine including makyoyokukanto extracts combined with powdered cinnamon bark and processed aconite root (makyoyokukanto plus) which were administered to 14 cases with chronic sciatica in the past year. The efficacy of Kampo medicine for lower leg pain relief was assessed using NRS (numerical rating scale). It was effective in 11 of 14 cases (79%, 6 males and 5 females, the mean age : 69), and not effective in 3 of 14 cases (21%, 2 males and 1 female, the mean age : 77). In 7 of 9 cases, who were given pregabalin before prescribing makyoyokukanto plus, makyoyokukanto plus was more effective than pregabalin. Furthermore, we have continued to observe 10 cases for over a year. Two of 10 cases were completely cured even if makyoyokukanto plus was discontinued. In 5 cases we switched from makyoyokukanto plus to yokuininto extracts combined with powdered cinnamon bark and processed aconite root, which was comparable to makyoyokukanto plus in its effect. Makyoyokukanto or yokuininto extracts combined with powdered cinnamon bark and processed aconite root were effective for chronic sciatica.

Chemical constituent change regulation of processed aconite during decoction and discussion on time limit of decoction based on metabolomics / 中草药

Objective: To analyze the change regulation of chemical constituent groups in processed aconite during decocting, and also to discuss the scientificity connotation of decoction of processed aconite. Methods: An ultra-high performance liquid chromatography coupled with time of flight mass spectrometry (UHPLC-Q-TOF/MS) was carried out to acquire the chemical constituents information in samples with different decoction time. High precise mass data were processed by multivariate statistical analysis techniques to discover and identify the constituents with significant difference. Furthermore, the content change, toxicity, and activity of these constituents were also discussed. Results: Fifteen chemical markers with significant difference were screened by partial least squares discriminant analysis (PLS-DA) and t test. By analyzing the change regulation of the different constituents during 4 h decocting process, we found that it mainly happened in the constituent dissolution and chemical transformation from monoester alkaloids to aconine alkaloids, which indicates the attenuation process is secondary. Conclusion: In terms of analgesic and anti-inflammatory effect, it suggests that 0.5 h of decoction would be fine, while in terms of cardiotonic effect, it needs the further systemic comparison for cardiac activity between monoester alkaloids and aconine alkaloids to be able to investigate the necessary and scientificity for long time decoction of the processed aconite.

Two Cases Successfully Treated with Tsumyakushigyakuto of Aconite Root Instead of Processed Aconite Root / 日本東洋医学雑誌

We report two cases successfully treated with tsumyakushigyakuto containing aconite root (<I>uzu</I>), instead of processed aconite root (<I>bushi</I>). The first case was a 33-year-old female. She had suffered from itching rashes in spite of being prescribed tsumyakushigyakuto with processed aconite root. Because she was in an extreme cold state, we changed the processed aconite root in her tsumyakushigyakuto to aconite root. Her itching rashes subsequently improved. The second case was a 42-year-old male. He had suffered from watery diarrhea and general fatigue in spite of being prescribed tsumyakushigyakuto with processed aconite root. Because he was in an extreme cold state, we changed the processed aconite root in his tsumyakushigyakuto to aconite root, and his watery diarrhea and general fatigue improved.<BR>We consider that using tsumyakushigyakuto with aconite root may be more effective than using it with processed aconite root in an extreme cold state.
