Elderberry
Sambucus
Overview
A native shrub whose dark purple berries and creamy flower clusters have been central to folk medicine and wild foods traditions for thousands of years across Europe and North America. Elderberry syrup has become one of the most popular natural immune-support remedies, with growing clinical evidence backing its antiviral properties. All parts must be cooked before consumption, as raw berries, bark, and leaves contain cyanogenic compounds.

Safety Notes
Although no specific mention has been seen for this species, the leaves and stems of some members of this genus are poisonous[9, 76]. The fruit of many species (although no records have been seen for this species) has been known to cause stomach upsets to some people. Any toxin the fruit might contain is liable to be of very low toxicity and is destroyed when the fruit is cooked[65, 76].
