According to research, “Goldenrod (Solidago spp.) is valued for its anti-inflammatory and antimicrobial properties. This herb can help reduce swelling and combat infections, has diuretic properties and assists in flushing out bacteria and even small kidney stones, making it a common remedy for urinary tract infections, kidney stone prevention, and may help with overactive bladder symptoms. It is also used to treat respiratory conditions such as sinus infections, bronchitis, and sore throats, consumed as a tea or used as a gargle. Its astringent qualities are beneficial for soothing inflamed mucous membranes in both the respiratory and urinary systems. Goldenrod is also used to support digestive health, helping to relieve bloating, gas, and diarrhea due to its high tannin content and carminative effects. It may also stimulate digestion and promote sweating which can help with detoxification.
If applied topically, for example as an essential oil mixed with a carrier oil like castor oil, goldenrod can be applied to wounds, burns, eczema, and other skin irritations due to its wound-healing, anti-inflammatory, and antifungal properties. It also helps with sore muscles, arthritis, and joint pain. Some studies suggest it may help reduce muscle spasms and relieve pain associated with conditions like bursitis and fibromyalgia. On an emotional and spiritual levels, Goldenrod helps to promote trust in self and confidence. Moreover, It is also a valuable plant for pollinators, supporting bees and butterflies, and can even be used as a natural dye for textiles!”
