Elderberry has been traditionally used to alleviate cold and flu symptoms. It is available in various forms, including syrups, gummies, and supplements. Elderberry syrup, in particular, is a popular choice for immune support and is often consumed during the cold and flu season. It’s essential to use elderberry products from reputable sources, as consuming raw or unripe elderberries can be toxic.
