SYNONYMS: S. canadensis var. gilvocanescens, S. altissima, S. canadensis var. salebrosa, Canadian goldenrod, meadow goldenrod, common goldenrod, giant goldenrod, tall goldenrod, rough goldenrod.

GENERAL DESCRIPTION: Solidago canadensis is a herbaceous, perennial plant of the daisy family often found growing as a wildflower, commonly forming colonies. The stem is stiff and erect, growing up to 7 feet high with numerous branches and lance-shaped leaves. The attractive small yellow or golden flowers are held above the foliage in clusters, which bloom late in the season. Goldenrod is often unfairly blamed for causing hay fever in humans although the pollen causing these allergy problems is mainly produced by ragweed, another wild plant which blooms at the same time. Goldenrods have a reputation of being difficult to control due to their aggressive rhizomatous growth, which enables them to rapidly colonize large areas.

DISTRIBUTION: Native to North America, the herb occurs in most US states and Canadian provinces. It is found in a variety of habitats, and it typically is one of the first plants to colonize an area after disturbance (such as fire) but rarely persists once shrubs and trees become established and is found neither in very dry locations nor in waterlogged ones. In many parts of Europe, Japan and China, it is considered an invasive weed, often endangering local fauna.

OTHER SPECIES: The genus Solidago comprises over 140 varieties, many of which are very similar; it can even crossbreed with other plants! Nearly all are known simply as goldenrod, though some have specific folk names such as woundwort, Aaron’s rod and Blue Mountain tea. Most of the goldenrod species are native to North America although a few are native to Europe, Asia, North Africa and South America. The European goldenrod (S. virgaurea), was known as woundwort in England as it was used as an astringent remedy for treating wounds and bleeding. The sweet goldenrod (S. odora), a native of the US and Canada, is the species most frequently seen in herb gardens and is also used to produce an essential oil used by the perfumery industry. Sweet goldenrod also has a long history of medicinal use by Native Americans and was exported for tea in the nineteenth century.

HERBAL/FOLK TRADITION: The genus name Solidago derives from the Latin soldare, which means ‘to make whole’. Goldenrod has a long history of medicinal use especially by the Native Americans who used the plant for a wide range of conditions: infusions and compounds of the flowers and roots were used as emetics, sedatives and to counteract love potions, treat diarrhoea, fevers and the ’flu. The Shuswap used the plant in baths for women giving birth and the Zunis chewed crushed flowers to treat sore throats and drank infusions of the flowers for body pain. People of the Gosiute tribe ate the seeds and the Navajo people ate the roots. The Navajo also smoked the root with other plants and used the plant as a charm for success in gambling. The ground flowers were used on bee stings and a tea made to treat snakebite. During the Boston Tea Party, colonists drank goldenrod tea instead of English tea, which gave it the nick-name ‘Liberty Tea’. The tea is aromatic with a pleasing anise-like flavour as well as being a mildly astringent, carminative, diaphoretic, diuretic, febrifuge and stimulant.

Traditionally the herb has also been used for respiratory conditions and urinary tract infections. In the Swiss Pharmacopoeia, Goldenrod essential oil is indicated for supporting the circulatory system including cardiovascular problems like tachycardia as well as urinary tract and liver function. Goldenrod has also been approved by the German Commission as a natural anti-inflammatory, diuretic and antispasmodic in the treatment of urinary tract conditions. It is also reputed to be a lymphatic system conditioner, a regulator of the autonomic nervous system, with relaxing and calming effects valuable for hypertension.

According to the University of Montreal in Canada, goldenrod shows great potential in dealing with impotence. Although a little-known aromatherapy essential oil, it may have value due to its anti-allergy properties, for conditions like hay fever, allergic reactions, coughs and respiratory infections.
