Forty-eight images of Goldenseal, Hydrastis canadensis root. Root traditionally used in tea or tincture to treat inflamed mucous membranes of mouth, throat, digestive system, uterus, also used for jaundice, bronchitis, pharyngitis, gonorrhea. Tea (wash) a folk remedy for eye infections. Recent research suggests a synergistic action of the major alkaloids in producing muscle-spasm reducing activity. When any single alkaloid was removed from the mix, the effect was greatly lessened. A 1998 study suggests that Goldenseal may help against drug-resistant tuberculosis, one of today’s most lethal infectious bacterial diseases.
