A to Z Herbarium: Ivy
Ivy is worn by brides for good luck; women will carry it for good luck in general. It protects against negativity and disaster wherever it grows or proliferates.
Symbolically, ivy is feminine. When paired with holly, which is symbolically masculine, it is said it will bring peace in the home between husband and wife for the following year.Though ivy is potentially toxic, especially in large doses, it has nevertheless been used to treat ailments such as asthma, bronchitis, colds, and sore throats. It apparently has even been used to get rid of stretch marks.
The thyrsus—a wand or staff used in worshiping Bacchus—was often wound with ivy.
