Jj. Lichius et al., The inhibiting effects of components of stinging nettle roots on experimentally induced prostatic hyperplasia in mice, PLANTA MED, 65(7), 1999, pp. 666-668
Direct implanting of fetal urogenital sinus (UGS) tissue into the ventral p
rostate gland of adult mice led to a 4-fold weight increase of the manipula
ted prostatic lobe. The induced growth could be reduced by the polysacchari
de fraction (POLY-M) of the 20% methanolic extract of stinging nettle roots
by 33,8 %.
