Remarkable effects within 2 weeks of combined Ryokyo-jutsukan-to and Keishi-buku-ryo-gan administration were reported in 3 subjects (1 male, 2 females; average age 78 years) with low back pain. Visual Analog Scale (VAS) was used when evaluating outcomes of low back pain and limb pain, and numbness in the lower limbs several weeks after combined administration of these drugs. A chill sensation in the lumbar region and polyuria were particular features involved in the prescription of the herbal medicine Ryokyo-jutukan-to. However, it was noteworthy that such symptoms were not necessary for the medication to be effect. In this study Ryokyo-jutsukan-to was effective in clinical symptoms similar to those caused by disc injury as described by McKenzie. Chronic low back pain is associated with blood stasis and stasis of bodily fluid. Consequently it may be assumed that Ryokyo-jyutukan-to is the best medication for some but not all patients with chronic low back pain.
