The use of Gentian root extract in the U.S. has an interesting history; it was considered a medicinal herb and was used as an ingredient of a patent medicine invented in 1876 by a physician in Maine. Back then, it was marketed as Moxie Nerve Food. Today, Moxie is sold as a soft drink in the New England states, and is still the official soft drink of Maine.
Gentiana lutea is one of those natural herbs that have an extremely strong and bitter taste. Dried Gentian root has traditionally been prepared as a decoction or tea.
