Not to be confused with the North American variety of red elderberry (Sambucus canadensis), the black elderberry is quickly emerging as "the immune berry," and for good reason.
Elderberry (Sambucus nigra) has traditionally been used in treatment for a variety of respiratory symptoms, with antibacterial and antiviral activity demonstrated in vivo.
There are several different types of elder trees, but European elder (Sambucus nigra) is the type most often used to produce berry extracts for supplements.
