Lachnanthes
Also known as Spirit weed, Carolina redroot, Paintroot, Lachnanthes.
Lachnanthes caroliniana, known as red root or spirit weed, is a perennial marsh and bog plant of the Haemodoraceae native to the wetlands of the eastern United States, named for the reddish woolly root that yields a dye once used by indigenous peoples. The root was taken up by nineteenth century eclectic physicians as a remedy for congestive throat and neck complaints and for nervous disturbance linked to alcohol excess, and it later became a well known homeopathic remedy keyed to stiff neck and mental confusion. Its use in mainstream Western herbalism has always been limited and its clinical record is thin compared with better documented plants.

Practitioners in the eclectic tradition reached for red root mainly for congestive, stiff, or catarrhal states of the throat and neck, often in patients whose complaints seemed to follow overindulgence in alcohol or who presented with a curious mental fogginess alongside physical stiffness. It was given in small doses of the tincture rather than large ones, reflecting both its potency and the caution eclectic writers exercised with it. Because solid modern clinical or pharmacological data are lacking, red root is best regarded today as a minor, historically interesting remedy rather than a first line choice. When used, it is typically reserved for cases matching its classic picture (a stiff, wry neck or a heavy congested throat with head confusion) and given for short periods with attention to response, rather than as a long term constitutional treatment.
