(Grindelia spp.) Grindelia is traditionally recommended for the treatment of spasmodic respiratory conditions such as asthma and bronchitis. The British Herbal Pharmacopoeia 1983 lists the specific indication as bronchial asthma with tachycardia.
Californian Native Americans used grindelia not only for skin infections but also for bronchial conditions where grindelia eventually gained the attention of the Catholic missionaries. The dried leaf and flowering tops of grindelia were official in the United States Pharmacopoeia 1882– 1926, and have been in the National Formulary, 1926–1960.
