People use cudweed for conditions such as high blood pressure, stomach ulcers, diarrhea, gut infections, and many others, but there is no good scientific evidence to support these uses.

Don't confuse cudweed (Gnaphalium uliginosum) with cat's foot (Antennaria dioica), which is also known as cudweed. Also, don't confuse cudweed (Gnaphalium uliginosum) with Pilosella officinarum; both are sometimes called mouse ear.
