ABSTRACT

A persistent dry cough can be caused from a upper respiratory infection or bronchitis. This study investigated the degree of cough relief with various plants that help relieve cough in Korea. The medicines used are Liriope platyphylla, Luffa aegyptiaca, Zingiber officinale, Angelica decursiva, Pseudocydonia sinensis, and Pyrus ussuriensis. The average number of coughs the day before taking herbal medicine was 96.4 times over day (both of day and night). The number of coughs on the 12th day after taking herbal medicine decreased to 27.6 times. The number of coughing times while sleeping was shown 17.1 times before taking herbal medicine and the 12th day of taking the herbal medicine averaged 6.0 times. The average time spent sleeping deeply was 3.8 hours before taking the herbal medicine and it was 4.5 hours after 12 days after taking the herbal medicine. The inhibitory effects of herbal medicines for nitric oxide (NO) radical scavenging activities were investigated. It was observed that scavenging activities go on increasing with enhancements in concentration of herbal medicines in the assay mixture. NO radical scavenging activities was evaluated 6.7% on 50 mg/L and 39.9% on 1200 mg/L.

Keywords: Dry cough, Liriope platyphylla, Luffa aegyptiaca, nitric oxide (NO) radical scavenging.
