I currently have access to a large amount of ripe Mahonia Aquifolium berries (Oregon Grape). Does anyone know how safe it may be to eat the berries in moderately large quantities on a regular basis? Including ingesting the seeds? Specifically, I have in mind mixing about a half cup or more in with my oatmeal every morning for at least a week. After preparing the oatmeal- mixing the 1/2 cup oats, 1/2 cup berries, and 2 TBSP ground flax, adding plenty of boiling water to fill up to the top of the food, covering, and waiting 15 minutes- the berries end up not being terribly bitter.
