Although not all side effects are known, elderberry (the active ingredient contained in Sambucol) is thought to be possibly safe when taken as directed for a short period of time.
Elderberry is possibly unsafe when uncooked leaves, stems, or fruit are consumed. The elderberry plant contains a chemical that produces cyanide in the leaves or other plant parts and in the unripe green fruit. This can cause nausea, vomiting, and diarrhea, or more serious side effects if consumed in large quantities.
Stop using elderberry and call your doctor at once if you have:
-
severe or ongoing vomiting or diarrhea;
-
numbness; or
-
severe weakness, dizziness, or confusion.
Common side effects may include:
-
nausea, vomiting;
-
stomach cramps;
-
diarrhea; or
-
runny nose.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects.
