Key Ingredients
- Mulethi/Yashtimadhu (Glycyrrhiza glabra) extract
- Karpur (Cinnamomum camphora - Camphor)
- Ela (Elettaria cardamomum)
- Lavanga (Syzygium aromaticum - Clove)
- Javitri (Myristica fragrans - Nutmeg/Mace)
- Pudina (Mentha piperita - Mint)
- Tulsi (Ocimum sanctum)
- Khatika (calcium compound)
Where is it described in the classical texts?
Referenced in Bhaishajya Ratnavali and Yoga Ratnakara (Kasa/Swarabheda Chikitsa - cough and voice disorder treatment sections); later elaborated in regional Ayurvedic formularies
How does it work?
- Expectorant and mucolytic: Yashtimadhu (glycyrrhizin) expels phlegm from lungs and airways; Javitri (nutmeg) has water-absorbing and sputum-absorbing qualities that thin and mobilize respiratory mucus
- Anti-inflammatory throat soothing: Glycyrrhizin and eugenol (from clove) reduce pharyngeal inflammation and provide analgesic relief for sore throat and irritation
- Antimicrobial protection: Camphor, clove (eugenol), and Tulsi (ursolic acid, eugenol) provide anti-inflammatory, antibacterial, and antifungal properties against upper respiratory pathogens
- Kapha pacification: The formulation is specifically effective against Kapha dosha predominant diseases, reducing mucus accumulation, congestion, and heaviness in the throat and upper respiratory tract
Which traditional uses are supported by research?
- Sore throat and pharyngitis relief validated through anti-inflammatory and mucosal-soothing mechanisms of glycyrrhizin and eugenol
- Cough management (Kasa) validated through demonstrated expectorant and mucolytic properties of Yashtimadhu and Javitri
- Voice improvement (Swarabheda) validated through throat-soothing and anti-inflammatory action reducing laryngeal inflammation
- Oral freshness and halitosis management validated through antimicrobial and deodorant properties of camphor, cardamom, and clove

Recent safety updates
- Generally safe as a lozenge/mouth-dissolving tablet for short-term symptomatic throat relief; camphor should not be given to very young children or in large doses; avoid continuous long-term use
- Not recommended during pregnancy without physician guidance; patients with hypertension should use cautiously due to Yashtimadhu (glycyrrhiza) content which can cause potassium depletion and fluid retention with prolonged use

Synergistic Combinations
Consult a qualified vaidya before acting on anything here. Ayurvedic practice is prescribed to a person, not to a condition: the same dravya is given, withheld or substituted depending on your constitution, your agni, the season and what else you are already taking. A page cannot know any of that. Self-prescribing from a reference is how the wrong preparation, the wrong dose or the wrong anupana gets used.
Educational reference only. Nothing on this page is medical advice, a diagnosis, or a recommendation to take anything. Traditional uses and research findings are reported as published, not as claims about what any product does. If you take prescribed medication, raise any interaction with the prescriber rather than acting on a page. See our editorial standards.
