Can a pill prevent altitude sickness? A randomized trial
Part of Lungs & breathing clinical trials.
This study tests if a traditional Chinese medicine pill (Suxiao Jiuxin Pill) can help prevent acute mountain sickness (the sickness you can get when climbing high mountains). Healthy volunteers who live near sea level will take the pill or a placebo and then go to a high altitude to see if it protects them.
Summary written for real people, not researchers, by Clin2.
