Results: Among the tested plant extracts, the extract of Asiasari radix showed the
most potent hair growth stimulation in C57BL/6 and C3H mice experiments. In
addition, this extract markedly increased the protein synthesis in vibrissae follicle
cultures and the proliferation of both HaCaT and human DP cells in vitro. Moreover,
the A. radix extract induced the expression of VEGF in human DP cells that were
cultured in vitro.
