Xiao Qing Long Tang is the next formula for breathing problems. My personal use of this is where I’ve been exposed to a wind cold invasion (ie a common cold) and my lungs are starting to experience restriction in moving. This formula warms the lungs and dispels cold and so is very good for acute flare ups of asthma that have been triggered by cold environments. However this formula contains Ma Huang, Ephedra, which has the ability to increase blood pressure and weaken prostrate functioning. Because of this herb this formula should only be taken short term. I’ve taken this one for a week once and found my prostrate control did indeed suffer. However, 24 hours after stopping prostrate was back to normal. This I’ve also prescribed for someone with breathing problems due to current virus doing the rounds and this improved their breathing significantly.
