The American Colombo root of commerce, formerly in transverse slices, now generally occurs in lengthwise slices. The outside is yellowish or pale orange and the inside spongy and pale yellow. The taste is bitter. American Colombo root resembles the official gentian root in taste and odor, and the uses are also similar.
