Burr marigold is little used as a medicine nowadays, but it was once esteemed for its styptic properties being used to quickly staunch blood flow - it was often used to treat uterine haemorrhage and conditions producing blood in the urine[254]. The whole plant is antiseptic, aperient, astringent, diuretic, emmenagogue, febrifuge, narcotic, sedative, styptic and sudorific[4, 61, 165, 218]. It is an excellent remedy for ruptured blood vessels and bleeding of any kind, and is of benefit to people with consumption[4]. It is used internally to treat bladder and kidney problems, blood in the urine, uterine bleeding, ulcerative colitis and peptic ulcers[238, 254]. Externally, it is used in the treatment of alopecia[238]. It is usually combined with a carminative herb such as ginger when used to treat digestive tract ailments[254]. The plant is harvested as it comes into flower and is dried for later use[238].
