Spanish Needle
Bidens pilosa
Long before it was studied in a laboratory, Spanish needle was already a fixture of household medicine chests on nearly every continent it reached. In West and East Africa it has traditionally been used as a poultice for cuts and skin irritation and as a tea for fevers and stomach troubles, while in Taiwan and across Latin America healers have steeped it for sore throats, upset stomachs, and general tonic support. It is also simply eaten, its young leaves tossed into soups and stews as a everyday leafy green, which is part of why this unassuming roadside weed became one of the most independently rediscovered medicinal plants in the world. Few herbs carry such a consistent reputation for gentle, all-purpose usefulness across so many unconnected cultures.

Traditional preparations.
A simple, traditional infusion used across many folk traditions to soothe the stomach and offer gentle, everyday support.
Steep 1 teaspoon of dried leaf (or 2 to 3 fresh leaves) in 250 ml of just-boiled water for 8 to 10 minutes, then strain and sip.
A traditional first-aid application using the same gentle infusion externally on unbroken skin.
Brew a cup of the leaf tea as above, let it cool fully, then soak a clean cloth and apply to the area for 10 minutes.
Safety.
Eaten as a leaf vegetable and folk tea and not considered toxic, but its blood sugar and blood pressure lowering effects mean it can add to diabetes or blood pressure medications. Confirm identification before foraging, since it resembles other roadside weeds, and it's best avoided during pregnancy and nursing since safety data is limited.
