Dranath is a fictional herb and drug in Melanie Rawn's fantasy novels of the Dragon Prince and Dragon Star trilogies. Dranath is grown only in the Veresch Mountains of Princemarch, the herb has several properties. When boiled, dried, and powdered, dranath can enhance the powers of a Sunrunner or sorcerer, while also helping Sunrunners cross water without illness. In this form the drug is very addicting; withdrawal will almost certainly kill the imbiber. Dranath can also cure the disease known as the "Plague", a malady which affects both humans and dragons. For non-gifted people this drug works as a hallucinogen.
