Destany "Sky" Pete, a member of the Shoshone and Paiute Tribes from the Duck Valley Indian Reservation, grew up hearing about toishabui, a traditional chokecherry pudding made with crushed chokecherry pits. After noticing rising health problems in her community alongside a decline in traditional diets, she decided to actually test whether the old recipe did what generations had believed.
Working with Dr. Ken Cornell, a biochemistry professor at Boise State University, Sky tested several versions of chokecherry against uterine sarcoma cancer cells in a lab dish. Only the authentic recipe made with the crushed pits worked. Within 24 hours, the cancer cells in that sample started dying.
Her project won First Grand Prize at the Elko County Science Fair in Nevada, beating out more than 440 other entries.
It's an early, single lab-dish result on one type of cancer cell, not proof the recipe treats cancer in real patients. But it's a genuine example of traditional knowledge holding up to real scientific testing, and Sky has said she plans to keep testing the recipe against other types of cancer cells going forward.
