Description of Plant(s) and CultureRock-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.
Where FoundFound in dry, sandy soils and rocky woods in the United States can be found as far south as North Carolina and Mississippi and as far west as Illinois and Wisconsin. Also found in Quebec.
Medicinal PropertiesAlterative, aromatic, astringent, tonic
UsesUsed 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.
Formulas or DosagesInfusion: steep 1 tsp. herb in 1 cup hot water for 10 minutes. Take 1 tbsp. 3 to 6 times per day. Tincture: a dose is from 5 to 10 drops
