Avabahuka (frozen shoulder), is a Vata-dominant Vikara characterized by shoulder pain (Bahu Shoola), stiffness (Bahu Stambha), and restricted mobility (Bahupraspanditaharatva). Nowadays, it is seen more frequently because of improper diet and behavioural habits. A randomized single-arm clinical trial was conducted on 30 patients diagnosed with Avabahuka. The treatment protocol involved initial Snehana and Swedana (Poorvakarma) followed by Marsha Nasya (Pradhanakarma) using Shuddha Bala Taila at a dosage of 8 Bindu per nostril for two 7-day sittings with a 3-day interval, as classical text Ashtanga Hridayam prescribes Brimhana type of Nasya for its management. Clinical assessment was performed using subjective parameters (Bahu Stambha and Bahu Shoola) with grading scales and objective assessment of shoulder movements using a goniometer. Statistical analysis was performed using the Wilcoxon Signed Rank Test. Significant improvement was observed in all assessed parameters (P < 0.05), with 62.50% improvement in Bahu Stambha, 66.67% in Bahu Shoola, and 56.57% overall improvement in shoulder movements. These therapeutic benefits are directly attributable to the Snigdha, Guru, Brimhana, and Vatashamaka properties of Shuddha Bala Taila, which pacify localized Vata and restore structural functional mobility, particularly in Swatantra Vataja Samprapti. Ultimately, the study confirms that Shuddha Bala Taila Nasya is an effective Ayurvedic intervention for relieving pain, overcoming stiffness, and restoring range of motion in patients suffering from Avabahuka, supporting the classical Ayurvedic principle, “अवबाहौ हितं नस्यं स्नेहश्चोत्तरभक्तिकः।”
