PEFR was measured in 82 male students following the ingestion of 15gm of Garcinia kola
. Overall, PEFR increased with age, height, weight and chest circumference. The lowest control PEFR was 450 L/min and the highest control PEFR was 647 L/min. Following the ingestion of Garcinia Kola
, PEFR decreased to 445 L/min and 615 L/min respectively at the end of 90 mins. Mean control PEFR was 576.17 ± 20 and mean PEFR 90min after Garcinia Kola consumption was 542 ± 26 (P < 0.05). Garcinia Kola may clear the airway, but does not improve the airflow in young adults.
