PROBLEM TO BE SOLVED: To provide a solid composition containing Polygala tenuifolia extract in which temporal change of color is suppressed.SOLUTION: The inventors found out that temporal discoloration of Polygala tenuifolia extract was suppressed when a specific cellulose-based disintegrator was blended. Specifically, a solid composition contains Polygala tenuifolia extract and at least one type of cellulose-based disintegrator selected from the group consisting of croscarmellose sodium, carmellose calcium and hydroxypropyl cellulose having a low substitution degree, and the content of Polygala tenuifolia extract powder is 10 mass% or more with respect to the entire solid composition.SELECTED DRAWING: Figure 1 |
