Can soap nuts be used for people with nut allergies?
According to Mountain Rose Herbs: Soap nuts are hypoallergenic, and can be used safely by people with nut allergies as they are a fruit closely related to the Lycii/Goji berry. There seems to be little information about the internal uses of soap nuts, although they certainly have been used as a solution to clean fruits and vegetables, so the evidence does suggest that they are of a benign nature if ingested.
