This study aimed to assess the effects of consuming basil tea on respiratory function and voice quality in healthy adults. Herbs are widely studied for their benefits on respiratory health and voice quality. Basil tea is noted for its anti-inflammatory and bronchodilatory effects, which may enhance vocal and lung performance. A total of 67 healthy adults aged 18 to 55 years were randomly assigned to an experimental group (n = 36), which drank basil tea (5 g fresh basil leaves steeped in 200 mL boiling water) twice daily for 10 days, or a control group (n = 31), which received no intervention. Maximum Phonation Time (MPT), Breath-Holding Time (BHT), the Voice Handicap Index (VHI), and the GRBAS scale were assessed immediately before and after the 10-day period using both objective and subjective measures. The experimental group showed significant increases in MPT (mean improvement: 3.41 s) and BHT, along with a significant decrease in VHI scores, indicating improved respiratory support, breath control, and voice quality. GRBAS scores also showed slight reductions in symptoms like roughness and hoarseness. The control group showed no notable changes. Younger participants improved more in MPT and BHT, while males had higher BHT values, likely due to greater lung capacity. Basil tea may improve respiratory function and voice quality in healthy adults, likely due to bronchodilatory and anti-inflammatory effects. Future studies with larger samples and longer follow-up are recommended to validate these findings and assess benefits for those with voice or respiratory disorders
