Sponsor: Far Eastern Memorial Hospital
Summary
Pneumonia is a major public health concern globally and domestically. Dyspnea experienced by hospitalized pneumonia patients often induces anxiety and psychological distress. Wintergreen essential oil, primarily composed of methyl salicylate, is commonly used for comfort care and respiratory relief. This study aims to evaluate the effects of wintergreen essential oil inhalation on dyspnea, physiological parameters, laboratory data, pulmonary function, and subjective comfort in hospitalized pneumonia patients.

Interventions
Sunflower oil inhalation
Pure sunflower oil is used as a placebo comparator. A volume of 0.5 mL (10 drops) is placed onto a 2-inch gauze held 5 cm away from the patient's nose for 8 deep breaths (approximately 30 seconds), administered 3 times daily for 3 consecutive days.
1% Linalool inhalation
High-purity (-)-linalool (Sigma-Aldrich, purity \>= 95.0%) diluted to 1% concentration with sunflower oil. A volume of 0.5 mL (10 drops) is applied onto a 2-inch gauze held 5 cm from the participant's nose for 8 deep breaths, administered 3 times daily for 3 consecutive days.
Wintergreen essential oil inhalation
Wintergreen essential oil containing methyl salicylate, diluted with sunflower oil into four concentrations: 0.5%, 1%, 2%, and 3%. A volume of 0.5 mL (10 drops) is dropped onto a 2-inch gauze held 5 cm from the patient's nose for 8 deep breaths, administered 3 times daily for 3 consecutive days.
