Onosma bracteatum
Also known as gaozaban, ox tongue, sedge-leaved onosma, Gojihva, Gojihvika, Gobhi.
Onosma bracteatum is a rough-haired perennial of the borage family from the drier inner ranges of the western Himalaya, Kashmir, Himachal, Afghanistan and Iran, with narrow tongue-shaped leaves that give it the Sanskrit name Gojihva, ox tongue. The dried leaves and flowering tops are the gaozaban of the Indian bazaar, a cooling demulcent for cough, fever, burning urination and an agitated heart that Ayurveda uses chiefly as the head of Gojihvadi kwatha and that Unani medicine prizes as a nervine and cardiac tonic.

Ask HerbertA pitta patient with a dry, tickling, persistent cough, a hot chest, thirst and a faint wheeze at night, where a cooling mucilaginous expectorant is wanted
The anxious, overheated, sleepless patient with a fluttering heart and a dry mouth for whom a cooling nervine rather than a heating one is right
Burning, frequent urination in a hot season or a pitta constitution, with a low-grade fever and no bacterial cause found
Low dose botanical. Used in drop doses in the classical practice; not a plant to dose freely.
Pregnancy: Avoid in pregnancy: no published safety class is known to us, but the genus is reported to contain pyrrolizidine alkaloids and the tradition offers no specific reassurance.
Breastfeeding: Avoid while nursing because pyrrolizidine alkaloids can pass into milk; a single dose of the traditional decoction is unlikely to matter, but courses should wait.

Gojihva earns its place for the hot dry cough. Gojihvadi kwatha, a decoction of Gojihva with Kantakari, Bharangi, Vasa, Pippali and other pectoral herbs, is a standard dispensary answer to kasa and shvasa with pitta and kapha, allergic bronchitis and cough after fever, given warm twice daily with honey.
Rasa: madhura (sweet), tikta (bitter), kashaya (astringent). Virya: sheeta (cooling). Vipaka: madhura (sweet). Guna: laghu (light), snigdha (unctuous), picchila (slimy). Dosha: pacifies pitta and kapha; the mucilage soothes vata in the chest and bladder. Karma: kasahara (relieves cough); shvasahara (relieves dyspnea); jvaraghna (relieves fever); mutrala (diuretic); hridya (cardiac tonic); medhya (supports mind and intellect); dahaprashamana (relieves burning); raktashodhaka (purifies blood); kaphanissaraka (expectorant); balya (strengthening). Classical indications: kasa (cough); shvasa (dyspnea, asthma); jvara (fever); mutrakricchra (painful urination); daha (burning sensation); hridroga (heart disease); unmada (mental disturbance); raktapitta (bleeding disorders); kushtha (skin disease); trishna (thirst). The dried leaf and flowering top are used, as a cold infusion or kwatha, as churna with honey, and as the leading herb of Gojihvadi kwatha; in the allied Unani tradition the same drug, gaozaban, is made into syrups, khamira confections and distilled waters for the heart and nerves. Classical formulations: Gojihvadi kwatha, Gojihvadi kashaya churna, Gojihva sharbat, Khamira gaozaban (Unani, widely dispensed), Arq gaozaban (Unani distillate). Described in: Charaka Samhita, Sushruta Samhita, Bhavaprakasha Nighantu, Raja Nighantu, Kaiyadeva Nighantu.
