Vyaghriharitaki Avaleha (VHA), a polyherbal classical Ayurvedic formulation has been used in Kasa (cough), Swasa (asthma), Rajayakshma (tuberculosis) etc., conditions.
Patients of chronic bronchitis were given 10 g of VHA twice a day with lukewarm water before meals for 12 weeks. Improvement in clinical symptoms of chronic bronchitis as the primary outcome measures and St. George's Respiratory Questionnaire scores as secondary outcome measure was studied.
Out of 66 enrolled patients, 61 completed the treatment schedule. The results show that VHA provides statistically significant improvement with P < 0.001 in both primary and secondary outcome measures.
