Borage is an annual plant native to Europe that is used in alternative medicine. It contains nutrients like potassium, calcium, and vitamin C. Medicinally, it is used to treat stress, anxiety, insomnia, lung complaints, fever, jaundice, and eye inflammation. Borage tea can be made from the leaves and flowers and consumed after meals. The flowers can also be made into jam to aid recovery from illness. Excess use may lead to addiction, so borage should be used in moderation.
