According to Margaret Joan Roberts in her book, "Edible & Medicinal Flowers," goldenrod was known in Europe as woundweed. In this context it was traditionally used to aid in the healing of skin wounds and abrasions. Roberts states that this herb possesses antiseptic and anti-inflammatory properties. This plant's genus name Solidago is derived from the Latin for "to make whole," a reference to its ameliorative powers, notes the University of Maryland Medical Center.
As well as being applied externally to wounds, goldenrod tincture may be consumed internally for its medicinal value. This herb is commonly used to treat ailments of the urinary system. According to the University of Maryland Medical Center, goldenrod is used to cure urinary tract infections and "flush out" kidney stones. Roberts says that goldenrod helps reduce the pain from backaches caused by kidney problems. And Erichsen-Brown asserts that among its other valuable uses, goldenrod can relieve pain resulting from flatulence.
According to the University of Maryland Medical Center, goldenrod has been used to treat diabetes, enlargement of the liver, internal bleeding, asthma and infections of the mouth and throat. Erichsen-Brown says the use of goldenrod extends to treating diarrhea, dysentery, headaches and nausea. And Roberts says the compounds known as saponins found in goldenrod combat the fungal infection known as Candida. She also suggests this botanical remedy for the treatment of chronic sinusitis, arthritis and nasal catarrh.
Goldenrod should not be used by those taking lithium, according to University of Maryland Medical Center. This is due to the fact that goldenrod's diuretic effects may cause lithium to build up in the blood.
