Uses: The berries and flowers of elderberry are packed with antioxidants and vitamins that may boost your immune system. They can help tame inflammation, lessen stress, and help protect your heart, too. Some experts recommend elderberry to help prevent and ease cold and flu symptoms, relieve headaches, constipation, fever and some infections that affect how you breathe.
Caution: If you are pregnant or breastfeeding, you shouldn’t take it. Other parts of the elder tree, including the branches, twigs, leaves, roots, and seeds, are toxic. They contain a type of cyanide called glycoside. People with immune problems might have reactions to elderberry. If you get a rash or have trouble breathing after you have some, you might be allergic to it. Because it’s a diuretic, be careful when you take it if you’re on medicines that make you pee more.
