The Medicinal Herb Info site was created to help educate visitors about the often forgotten wisdom of the old ways of treating illnesses. Many of today's drugs and medicines were originally derived from natural ingredients, combinations of plants and other items found in nature.

We are not suggesting that you ignore the help of trained medical professionals, simply that you have additional options available for treating illnesses. Often the most effective treatment involves a responsible blend of both modern and traditional treatments.

We wish you peace and health!

Description of Plant(s) and Culture

Rock-rose is a native North American perennial plant, 6-20 inches tall; the unbranched, downy stem bears alternate, linear-oblong, toothless leaves, 1/2 to 1 inch long and about 1/4 as wide, which are dark green above and downy white beneath. The plant flowers twice in a season: the first solitary flowers with many stamens are bright yellow and have large petals that drop a day or so after opening; later another set of inconspicuous flowers develop, without petals and few stamens, growing in axillary clusters. Blooms May to July. The whole plant has a slight aromatic odor, and an astringent and bitter taste.

Used relatively little, at least alone. Can be used for diarrhea, mouth, scarlatina, and throat irritations, and skin problems. Has been used at times as an eyewash. In large doses it acts as an emetic.

Native Americans used leaf tea for kidney ailments, sore throats. Patients were covered with a blanket “tent” to hold steam; feet soaked in hot tea for arthritis, muscular swellings, and rheumatism. Historically, physicians once used a strong tea for scrofula(tuberculous swelling of lymph nodes), for which it was reported to produce astonishing cures; also diarrhea, dysentery, gonorrhea, and syphilis. Externally, used as a wash for skin diseases such as prurigo, and eye infections; gargled for throat infections. Leaves poulticed on scrofulous tumors, sores, and ulcers; said to be helpful in treatment of some forms of cancer.
