Gojihva: Traditional Uses, Research & Safety

Q: What is gojihva?

Gojihva is the Ayurvedic name for Onosma bracteatum Wall., a hairy Himalayan herb in the borage family, also used in Unani medicine as Gaozaban. It is considered a "controversial" drug because several species are traded under the name (Int J Pharma Investigation).

Q: What is gojihva traditionally used for?

A 2022 IJAPR review records traditional use for fever, cough, bronchitis, rhinitis, stomatitis, and weakness of the heart muscles, with more than 20 indications across the Samhita literature (Goyal et al., 2022). These are traditional records, not proven effects.

Q: Is there any clinical evidence for gojihva?

No. No controlled human trials were identified in the cited sources. All pharmacological evidence (diuretic, antimicrobial, liverprotective, anticancercell effects) comes from animal or laboratory studies (Goyal et al., 2022).

Q: Why is gojihva called a controversial drug?

Because roughly six different species are sold as "gojihva" in medicinalplant markets, so the name alone doesn't guarantee the botanical identity (Int J Pharma Investigation).

Q: Is gojihva safe?

Unknown in humans: no controlled safety studies exist. Given the identityconfusion problem and the absence of human data, it should only be considered under qualified guidance, not selfprescribed.

TL;DR

Gojihva (Onosma bracteatum) is an Ayurvedic herb traditionally used for cough, fever, bronchitis, and heart weakness. No controlled human trials were identified in the cited sources: all pharmacological evidence comes from animal and cell studies (diuretic, antimicrobial, liver-protective effects). It is considered a "controversial" drug because several species are sold under the name; product identity is a safety risk.

What it is

Gojihva is the Ayurvedic name for Onosma bracteatum Wall., a perennial, densely hairy herb in the borage family (Boraginaceae) that grows in the north-western Himalayas at altitudes of 3,500–4,500 m (diuretic/pharmacognosy study). It is also known as Gaozaban in the Unani tradition. An Indian pharmacognosy paper describes O. bracteata as the Ayurvedic Pharmacopoeia of India–recognized source of gojihva, one of about six species traded under the name, which is why gojihva is called a "controversial" drug: the name on a packet does not always mean the same plant (same paper).

Traditional use

A 2022 review in the International Journal of Ayurveda and Pharma Research (IJAPR) summarizes gojihva as a plant "commonly used for fever, cough, bronchitis, rhinitis, stomatitis & weakness of cardiac muscles" across the Unani, Ayurvedic, and other traditional systems (Goyal et al., 2022). The review concludes the Samhita literature records more than 20 indications, including kasa (cough), shwasa (breathing difficulty/asthma), jwara (fever), hridya roga (heart disorders), vrana ropana (wound healing), grahi (absorbent action), and prameha/mutrakrichra (urinary disorders) (same review). These are traditional records, not clinical proof: the human-trial evidence is assessed below.

What modern research says

Human trials: none found

No controlled human trials of gojihva were identified in the cited sources. The IJAPR review's conclusion is that gojihva's traditional indications should be compared against the pharmacological data and "areas of further research are identified": in other words, the clinical work has not been done (Goyal et al., 2022).

Animal and laboratory studies

All reported pharmacological effects come from preclinical work:

Diuretic effect (animal): In rats, methanol extract of O. bracteata at 100 and 200 mg/kg produced a highly significant increase in urine output at 6 hours (p<0.0001), while the aqueous extract showed only mild activity (Int J Pharma Investigation).
Antimicrobial (in vitro): Extracts showed zones of inhibition against E. coli, Bacillus subtilis, Staphylococcus aureus, Klebsiella pneumoniae, and Pseudomonas aeruginosa (Kazmi & Baig, J Pharm Bioallied Sci 2025).
Liver protection (animal): Antioxidant constituents from O. bracteata ameliorated carbon-tetrachloride–induced liver damage in male Wistar rats (Kumar et al., Front Pharmacol 2020, via review).
Cell studies: Laboratory reviews summarize reported anticancer cell-line activity of Onosma preparations (Bentham review). Isolated benzoquinones extended replicative lifespan in a yeast aging model (Farooq U et al. "Novel Anti-Aging Benzoquinone Derivatives from Onosma bracteatum Wall." Molecules. 2019;24(7):1428. DOI: 10.3390/molecules24071428).

None of these are human evidence. The IJAPR review lists many more reported preclinical effects (analgesic, anti-asthmatic, anxiolytic, cardioprotective, and others) but notes they come from pharmacological studies, not patients (Goyal et al., 2022).

Dosage

No pharmacopoeial or clinical-trial dose for gojihva could be verified, and with no human trials published, no dose can be stated responsibly. Do not self-dose based on traditional indications.

Safety & contraindications

No controlled human safety studies of gojihva have been published: safety in pregnancy, breastfeeding, children, or alongside prescription medicines is simply unknown. Because several different species are sold as "gojihva," product identity is itself a risk: choose only manufacturers that print the Latin binomial (Onosma bracteatum) and batch-testing information. Anyone considering it should talk to a qualified practitioner first.
