Eye, Ear, Nose and Mouth Care in Ayurveda: Trataka, Nasya, Karna Purana and Gandusha

What this page covers

Ayurveda describes care for the senses and the head in some detail. This page explains four named practices in general terms: trataka (eyes), nasya (nose), karna purana (ear) and gandusha (mouth). It gives no instructions for any of them. Ear oil, nasal oil and eye preparations should be used only on a clinician's advice.

Trataka: steady gazing

Trataka is a yogic cleansing technique [2] in which a person gazes steadily at a point or a candle flame. [3] Trials have tested it for eye strain, attention-type tasks and anxiety. We give no technique here.

Do not use trataka as treatment for glaucoma, and do not change prescribed eye drops. Staring at a bright flame is not appropriate for everyone; ask an eye doctor if you have an eye disease. For ordinary digital eye strain, the American Academy of Ophthalmology says screens do not permanently damage the eyes, and suggests blinking more, looking into the distance and adjusting brightness and position. [6] People blink about 15 times a minute normally but only 5 to 7 when using screens. [6] For dry eyes, the NHS advises breaks from screens and seeing an optician or GP if they last for a few weeks. [7]

Nasya: oils or medicines in the nose

Nasya is the Ayurvedic administration of medicines through the nose, one of the five panchakarma procedures (called errhine therapy). [8] One form, marsha nasya, uses mainly oil-based medicines in a relatively larger amount. [8] A 2026 Indian study of nine experts reached consensus statements because panchakarma therapies currently lack published contemporary practice guidelines. [8] That is a consensus of practitioners, not a trial of benefit.

Evidence. Nasya was one of several interventions in a systematic review of 11 mostly small Ayurvedic studies on insomnia in older adults; limitations included small samples, no comparators and unregistered trials. [9] Proper evidence not found for nasya on its own for any specific condition; we searched PubMed for nasya trials and found protocols, case reports and combined treatments.

Safety. A case report describes lipoid pneumonia (a lung inflammation from inhaled oil) after long exposure to paraffin-oil nasal drops. [10] That was a mineral oil, not a herbal one, but it shows why oils in the nose are not harmless. Ask a clinician before putting anything in the nose. For the full panchakarma picture, see Panchakarma and Ayurvedic Cleansing Procedures.

Karna purana: oil in the ear

Karnapurana means filling the ear canal with medicated oil. A trial protocol describes it as a treatment advised in the tradition to counter Vata, improve hearing and reduce tinnitus. [11] The only clinical material we found is a case report of one 75-year-old man [12] and a protocol for a planned 60-person trial in India without results. [11] Evidence label: traditional use only; insufficient evidence. We give no instructions.

Safety. The NHS says earwax usually falls out on its own, advises not to use fingers or cotton buds, and says not to use drops if you have a perforated eardrum. [13] Anyone with ear pain, discharge, hearing loss or tinnitus should have the ear examined first; see a GP if tinnitus is regular, constant or worsening. [1]

Gandusha and kavala: the mouth

Gandusha and kavala are the Ayurvedic terms for holding or swishing a liquid in the mouth. A 70-patient Indian trial (60 analyzed) in head and neck cancer found an Ayurvedic mouthwash (used as kavala) was associated with less severe radiotherapy mouth side effects than a soda-salt rinse, but it was not blinded and was financially supported by AYUSH (India's traditional-medicine ministry). [14] That was supervised cancer care, not a model for self-treatment. For oil pulling, see Oil Pulling and Ayurvedic Dental and Oral Care. One review of tooth brushing in Ayurveda describes twigs and herbal powders as part of daily routine. [15]

Product quality and practitioners

Some Ayurvedic preparations contain lead, mercury or arsenic in toxic amounts. [16] See Ayurvedic Products: Heavy Metals and Product Quality. No US state requires a license for Ayurvedic practitioners. [16] See Choosing an Ayurvedic Practitioner.
