Goldenrod is an excellent anticatarrhal, meaning it reduces the production of mucus in the bronchi by decreasing inflammation in the mucous membranes. This helps make the sufferer more comfortable while the body is eliminating pathogens and waste products from the respiratory tract during infection.
Goldenrod is believed to boost renal function, making it useful in acute cases of nephritis.
As a topical, goldenrod can help clot blood and inhibit bacterial infection of minor cuts and abrasions.
Goldenrod may also help pollen allergies if taken for several weeks prior to the start of hay fever season.
For helping reduce inflammation of respiratory mucosa, use a teaspoon of dried herb in 8 ounces of water, cooled to lukewarm, as a tea.
As a topical, apply powdered goldenrod flowers liberally to stop bleeding.
