Water pepper
Polygonum punctatum
Also known as Smartweed, Dotted smartweed, Water smartweed, Polygonum, Smart-weed.
Water pepper is an annual to short-lived perennial herb of wet meadows, ditches, and marsh edges across North America, closely related to the European water pepper of herbal tradition. The fresh flowering aerial parts are used, prized for a hot, biting, peppery taste on the tongue that gives the plant its common name. It held a defined place in nineteenth century Eclectic practice as a warming stimulant with particular affinity for the uterus and the skin.

Suppressed or delayed menses following a recent chill, with dragging low pelvic cramping
Cold or ague with dry hot skin and no sweat, when a diaphoretic push is wanted
Passive uterine or capillary bleeding with cold, sluggish circulation
Safety
Low dose botanical. Used in drop doses in the classical practice; not a plant to dose freely.
Pregnancy: Avoid in pregnancy: traditional use as an emmenagogue and uterine stimulant is inconsistent with safe use in pregnancy.
Breastfeeding: Insufficient data to support safe use during lactation; avoid or use only under professional guidance.
The record lists 5 contraindications; open the plate in the library to read them in full.
In practice
Water pepper is reached for when a cold or suppressed menstrual flow follows a chill and the skin stays dry and unresponsive. Eclectic physicians valued the fresh tincture as a reliable stimulant diaphoretic that could be paired with warming carminatives such as ginger for the early stage of a cold, and as an emmenagogue for amenorrhea specifically tied to a recent chill rather than to general debility or anemia.

From the sources
Overview. Water pepper is an annual to short-lived perennial herb of wet meadows, ditches, and marsh edges across North America, closely related to the European water pepper of herbal tradition. The fresh flowering aerial parts are used, prized for a hot, biting, peppery taste on the tongue that gives the plant its common name. It held a defined place in nineteenth century Eclectic practice as a warming stimulant with particular affinity for the uterus and the skin.
Clinical Notes. Water pepper is reached for when a cold or suppressed menstrual flow follows a chill and the skin stays dry and unresponsive. Eclectic physicians valued the fresh tincture as a reliable stimulant diaphoretic that could be paired with warming carminatives such as ginger for the early stage of a cold, and as an emmenagogue for amenorrhea specifically tied to a recent chill rather than to general debility or anemia.
Therapy. In suppression of the menses from cold, thirty drops in hot water may be drunk every two hours. It is a prompt remedy. It may be begun two weeks before the menses should next appear, if one period has passed, and given every four hours in cold water, until a day or two before the expected time, when it can again be given in hot water.
Specific indications and reasoning. (WATER PEPPER.) Preparation: Prepare a tincture from the fresh herb, in the proportion of 5viij. to Alcohol 76° Oj. Dose gtts. ij. to 388. I regard the tincture of Water-Pepper as one of our most certain stimulant diaphoretics. It is also oue of the best emmenagogues, especially when the arrest is from cold. It influences the urinary and reproductive organs, but its action in these directions needs to be studied.
