About a hundred years later, a certain Mrs. L. S. M. Curtin studied the Yuki Indians of Round Valley and listed the plants they were using. In her writings “sixteen medical plants were listed, half of which belonged to species or genera which were admitted to the official drug compendia” . This list was expanded by John Culley, who described about
forty different plants and remedies that were used by the California Indians, among them more than three that were accepted by the U. S. Pharmacopeia as real and effective medicine: the Eriodictyon californicum, the Rhamnus purshiana and the Grindelia Robusta. Slowly the world started to recognize the values of the Native American medicine, replacing their earlier suspicious attitude with a more trusting approach.
The biggest shock came when the leading countries like Britain and France reported cases when a simple aboriginal remedy, for example lemon juice, was more effective than the complex procedures that they were used to. The tribe healers were not considered to be charlatans anymore; they were rather geniuses in the eyes of the Europeans.
