The histological score was calculated using a scale from 0 to 3, 0: none, 1: mild, 2: moderate, and 3: severe.

^aValues are significantly different from G4, G5, G6, and G7 (P < 0.05).

^bValues are significantly different from those of controls (G1–G3) (P < 0.05).

^cValues are significantly different from those of silibinin (G5) (P < 0.05).

^dValues are significantly different from G7 (400 mg pollen/kg B.W.) (P < 0.05).
