until some sensible effect is produced, afford in dysuria speedy relief;
in hemorrhage from the bladder, kidneys, or uterus, its acts as a
powerful styptic. See _Form. 35, 60, 97, 114_. Externally, it is very
efficacious in destroying venereal warts, either used alone, or diluted
with a small portion of water. _Dose_, ♏︎x to fʒss, or fʒj.[693]
