ABSTRACT
<p>In 2013, we prescribed daiuzusen for 3 patients with intractable pain; pain from complex regional pain syndrome, colic pain of unknown origin after an abdominal operation, and colic pain from advanced colon cancer and ileus. A dose of daiuzusen (containing uzu 0.5-2 g) quickly relieved their pain in several minutes. Another common symptom was “cold” in their bowel or extremities when they were feeling pain. Aconite levels in drugs and patients' serum after taking daiuzusen were analyzed by liquid chromatography tandem mass spectrometry. Daiuzusen per 1 g of uzu contained aconitine 1.28 μg, mesaconitine 2.31 μg, and hypaconitine 92.89 μg, while jesaconitine was not detected; this was about 5 to 35 times the level of tsumyakushigyakuto per 1 g of uzu. Serum concentrations of hypaconitine peaked in the study at 1.11 ng/mL after about an hour of taking daiuzusen (1 g of uzu). We posit that the immediate effect after taking daiuzusen was due to transmucosal absorption of uzu components. However serum hypaconitine, which we are now able to monitor, is at least one practical way of indicating the use of uzu or bushi containing prescriptions.</p>
ABSTRACT
Heat-treated and detoxified Aconite tuber has many useful properties such as analgesic, diuretic, and cardiotonic effects. Two hundred forty-seven patients were treated with Aconite Tuber powder (1.5 - 8.0g/day) added to Kampo extract granules. The Visual Analog Scale (VAS) was used for the assessment of its pain-relieving effect. One hundred two patients improved dramatically (the pre/post administration VAS ratio was less than 50%), 84 improved (between 51 to 75%), and61did not improved (more than 76%). Three patients(1.2%) showed adverse reactions, such as tongue numbness, squeezing sensation of the bladder, anasarca. These reactions were not serious. This study suggests that Aconite tuber powder can be used more widely, especially for arthralgia and somatic pain with coldness in elderly patients.

In order to evaluate the effect of shuchi-bushi, a powder form of the aconite tuber, we examined changes in finger temperature (FT) and tissue blood flow (TBF). No significant differences were observed in FT between pre-administration and 90 min post-administration, however, FT at 72 min was significantly higher than that at the pre-administration (p=0.0736and p=0.0219, respectively). The FT at 72 h was also significantly higher than that at 90 min (p=0.0253). No significant differences were observed in TBF between pre-administration and 90 min, nor between the 90 min and 72 h. However, the TBF at 72 h was significantly higher than that at pre-administration (p=0.0219). A significant correlation was observed between the FT and TBF (p=0.0052). Our results suggest that shuchi-bushi may play a role in warming and increasing tissue blood flow in human.
