CONSTITUTION:The subject preparation contains, as an active ingredient, at least one from flavonoids, saponins and their glycosides occurring in leguminous plants. Particularly preferable ingredients are isoflavonoids or triterpenoidal saponins, and they are combined with a solid or liquid medicinally acceptable excipient. The preparation is in the form of internal use, suppository, or injection. The isoflavons and triterpenoidal saponins are obtained by extracting roots or flowers of arrow roots with a lower aliphatic alcohol, concentrating the extract under reduced pressure, suspending the residue in water and partitioning the components using n-butanol or other solvents. |
