Summary
Brief summary
During trials on Artemisia Annua’s use for malarial treatment anecdotal evidence emerged of its beneficial effect on inflammatory processes including asthma. This has led to further studies specifically looking its anti-inflammatory role. It has been shown to have a direct effect on human bronchial epithelial cells and a study looking at its effect on a mouse allergic asthma model was very promising.
Previous studies have shown the anti-inflammatory potential of Arthrem in vitro and previous animal studies have shown a benefit of the active ingredient Artemisia annua in the treatment of asthma. The mechanism of action of this drug is thought to be downregulation of the inflammatory cascade in the airways of patient’s with inflammatory asthma, but the exact mechanism remains undetermined.
This study is a randomized double blinded randomized control trial looking to compare asthma control in 2 groups. One group will be given the herbal supplement Artemisia annua 175mg twice a day and the other will be given a placebo containing rice flour. It will involve participants over the age of 12 with a less than 10 year smoking history with a diagnosis of stable asthma. It will last 6 months and involve the comparison of asthma control as measured by peak flow, pulmonary function tests and a questionnaire.
