Uses

The pulp of the cherry is edible. However, the seeds of the hollyleaf cherry are considered to be toxic, and the plant must undergo certain leaching processes to make it safe for consumption. Native Americans fermented the fruit into an intoxicating drink. Some also cracked the dried cherries and made meal from the seeds after grinding and leaching them. It has also been made into jam. The method of preparation for the cherry was to first extract and crush the kernel in a mortar, and the resulting powder would then be leached in order to eliminate remaining bad chemicals. The final step was to boil the leached powder into an atole. Once this process was completed, Native Californians would then make soup base, tortillas, or tamale-like foods using the resulting ground meal. Other times, the kernel would be kept whole, leached to remove its hydrocyanic acid content, roasted for a couple hours, and then used to make cakes or balls. Aside from food, the hollyleaf cherry was also used for medicinal purposes by some Native Californian tribes, including the Diegueño and the Cahuilla. Specifically, infusions made from the bark and roots of hollyleaf cherry plants would be used as treatment for common colds and coughs.
