This sounds like a very interesting tip, which I was just notified about by a steemit user, but no guarantees, please check for yourself if this is a safe recommendation BEFORE trying this: ==== https://steemit.com/asthma/@devadd/asthma-and-it-s-problems ==== A plant named vitex negundo is the only best cure for asthma. Take a bowl full of the leaves and boil in hot water and cover yourself with a bedsheet and deeply steam it by inhaling the steam. Follow this weekly once. You won't experience asthma for lifetime.
