Erigeron canadense

Made from Canada fleabane — the wayside weed whose extract was an official haemostatic of the old United States Pharmacopeia, and the classical remedy of bleeding with burning.

The whole picture, in one breath

Think of bleeding with burning: bright-red blood from the bladder with smarting and burning, bleeding piles that sting, flooding menses, and — the books' signature — haemorrhage after exertion or injury, with the part feeling burned. Bright bleeding with burning: that is Erigeron.

The substance, in plain words

Canada fleabane is the tall wayside weed of North American roadsides, its oil-rich herb an official haemostatic and urinary drug of the old USP — a genuine working remedy for bleeding and bladder irritation, retired when modern urology and hemostatics arrived.

Where the classical picture comes from

The official USP haemostatic gave the remedy its raw material; the proving added the burning signature, and Erigeron entered the classical library as the bright-bleeding-with-burning remedy of the bladder and bowel.

The substance in real medicine Pharmacology

What this section is: the pharmacology and toxicology of the source substance. It is not clinical evidence that a homeopathic preparation of it treats any condition. What controlled trials do and do not show is set out on the Evidence page.

Fleabane was a genuine official drug — the United States Pharmacopeia listed its fluid extract as a haemostatic and urinary astringent for decades. Its oil chemistry (including compounds studied as anticancer leads) is real; its medical career, like Trillium's, was honourable and is now history.

Look-alikes (how the classical authors told it apart)

RemedyLooks similar because…Tells it apart because…
Trillium pendulumBright bleedingTrillium's bright bleeding sinks the patient at once; Erigeron's burns and stings.
Cantharis vesicatoriaBladder burningCantharis scalds with cutting pain and constant urging; Erigeron bleeds bright with burning.
Hamamelis virginianaBleeding pilesHamamelis' piles are bruised, dark and venous; Erigeron's bright and burning.
MillifoliumBleeding, woundsMillifolium is the wound-and-congestion bleeder; Erigeron the burning bladder one.
Safety. Blood in the urine is never normal — medical assessment is essential; heavy bleeding of any kind needs urgent care.
