A: Great question! Some substances that have immune stimulating properties, like spirulina and chlorella, can worsen autoimmunity, and even cause new onset autoimmunity. Adaptogens, on the other hand, work by helping to bring the body back into balance, and can help to modulate the immune system. By definition, to be considered an adaptogen, the herb needs to be able to both tone down overactive systems and boost underactive systems in the body. So, while an apoptogenic herb may have immune boosting properties, the herb should help the body to return to a “normal” state regardless of how the stress is currently affecting the person’s function.
