Some people noticed that consuming the fruit caused diarrhea, while others reported that the fruit was an excellent laxative. Native Americans used the yellow roots or bark to make a yellow dye to color baskets, wool, or porcupine quills; it is still used today as a natural dye for wool.Native people ate the sour fruits fresh in small quantities or dried them in the absence of other fruit; others made preserves or jelly."
