Allergies occur as a result of some type of malfunction in the immune system, and can be triggered by many different substances in the environment, including food ingredients. In Asian medicine, they are traditionally treated with remedies designed to balance the immune system, rather than suppressing symptoms with medications.

In Asia, goji berries have traditionally been used as a therapy for allergies. Chinese scientists have observed that the fruit reduces antibodies that are generated in response to an allergen. In addition, the polysaccharides in goji are believed to enhance normal function of the immune system. The net effect is a restoration of healthy immune function.
