Golden Rod has a peppery taste. I have eaten the root when young and it is tasty but not so tasty when it gets older. It has great detoxing and antibiotic properties. It helps reduce coughing. Most only eat the leaves and flowers. I do know it must kill tick born illness because when I first drank tea made from it I herxed very bad.
In low doses in increases reactive oxygen species and in high doses it lowers them.
Has antibacterial properties
Inhibits cancer growth.
