Quick fix: bleeding.
Styptics will stop bleeding.
I've given shepherd's purse (Capsella bursa-pastoris, green parts) to ladies with too heavy menstrual bleeding and it has worked a treat.
I've used Usnea (lichen, tincture) on bleeding fingers and that works nicely, too.
I've picked Lamium album (white deadnettle) flowering tops for years now, but have used it in ladies' troubles and only recently read that it's a styptic, too - but I haven't tried it yet.
Others tell me that they've used yarrow (Achillea millefolium) as a styptic; haven't used it that way myself.
I'm sure there are more plants which are effective and fast styptics.
