Scientists have published a report that suggests the proteins in Spirulina, the blue green algae can reduce histamine release from mast cells (found in the immune system). A study published in the Journal of Medicinal Food indicates that Spirulina made a significant improvement in patients with nasal allergies (allergic rhinitis).
Spirulina grows in fresh water and can be dried as a super power food supplement that contains every single nutrient our body needs. In fact Spirulina is per calorie one of the most nutrient dense proteins available for human consumption.
The beneficial anti-allergy effects of Spirulina were found to significantly improve irritating symptoms such as nasal discharge, sneezing, congestion and itching.
Over the counter anti-histamines serve to suppress the immune system. Although they may stop your streaming eyes and runny nose they also make you more susceptible to illness.
