Discussion

Although it and other goldenrods are commonly blamed for hay fever, this discomfort is usually caused by pollen from Ragweed (Ambrosia spp.), which are less conspicuous plants with greenish flowers that bloom at the same time. A poultice of the flowers has been used in the treatment of ulcers and burns. A poultice of the moistened, crushed root has been used in the treatment of boils. It has also been used as a treatment for some cancers. The leaves are also a source of latex, and a good source of rubber.
