Culpeper's The Complete Herbal (1653) - On Southernwood
A Brotanum, mas, fœmina.
Southernwood, male and female. It is hot and dry in the third degree, resists poison, kills worms; outwardly in plaisters, it dissolves cold swellings, and helps the bitings of venomous beasts, makes hair grow: take not above half a dram at a time in powder. 
Culpeper also lists Southernwood as an herb that cleanses, ‘provokes the terms’ (causes menstruation) in women, and resists poisons .
