Gaozaban, botanically known as Onosma bracteatum (and often associated with Borago officinalis), is one of the most prestigious herbs in the Greco-Arabic (Unani) system of medicine. The name "Gaozaban" is derived from Persian, meaning "Cow’s Tongue," referring to the rough, textured shape of its leaves. Native to the Himalayas and Mediterranean regions, it is classified as having a "Warm and Moist" (Garm-o-Tar) temperament. It is celebrated as the "King of Exhilarants," used for millennia to uplift the spirit, strengthen the heart, and nourish the nervous system.
