Prevention of loss of whiskers in D-galactose-induced aging mice.

Treatment group	Loss of whiskers (% mice)
	0	+
Veh	100	0
d-gal∗	50	50
d-gal + BYPA	100	0
d-gal + BYP	100	0
d-gal + BYA	100	0
d-gal + BPA	100	0
d-gal + YPA	100	0

n = 12 mice/group. “0”: no loss of whiskers; “+”: loss of whiskers.

^∗Based on two-sided Fisher's exact test, the d-gal group with 6/12 whisker loss differed significantly from the Veh group with 0/12 whisker loss (p = 0.014), from each of the BYPA, BYP, BYA, BPA, and YPA extract-treated groups showing 0/12 whisker loss (p = 0.014), and from a combined herbal-treated group with 0/60 whisker loss (p = 5.9 × 10⁻⁶). Photographs of representative mice from the different treatment groups are illustrated in Figure 3.
