Powdered epilobium has been used to control internal haemorrhage. It has also proven useful in controlling urinary incontinence in both men and women.
Historically, medicinal use includes oral use of the plant extracts, often in the form of an infusion or tea, as a treatment for prostate and urinary problems including benign prostatic hyperplasia (BPH) or enlarged prostate; and for various gastrointestinal disorders such as dysentery or diarrhoea.
Topically the plant has been used traditionally as a soothing, cleansing and healing agent to treat minor burns, skin rashes, ulcers, and numerous other skin irritations and afflictions.
Epilobium is used to treat prostate problems, bladder problems and bedwetting. It may also be beneficial to the kidneys.
To make an infusion, use 1 heaping teaspoon of the dried herb per ¼ litre of water. Drink only two cups per day, one in the morning before eating, and the second a half hour before you eat dinner. To make the infusion, pour your boiling water over the herb and let steep for ten minutes. Strain before drinking.
