Hair follicle growth in telogen-matched C57BL/6 N mice treated with T. orientalis extract. The effect of T. orientalis extract (5.05 mg/cm2/day) on the hair follicles of telogen mice was analyzed using hematoxylin-eosin (H&E) staining. (a) Transverse sections of the back skins (0, 7, 14, and 21 days) were stained, and representative photomicrographs of skin sections were shown. Bars, 100 μm. A–D, control; E–H, T. orientalis extract; I–L, 1% minoxidil. (b) The number of hair follicles in deep subcutis. Values are mean ± standard deviation (S.D.) (n = 10/mouse; **
p < 0.01 and ***
P < 0.001, vs. control).
