I have this post about flu tea https://steemit.com/prepper/@elew/herbal-prep-making-cold-and-flu-tea
At the end is a list of other herbal posts, but I will add this one on Asthma. https://steemit.com/prepper/@elew/herbal-prep-asthma
I will try to do one on general histamine reactions soon...but I am not sure what to do for reactions where one would need an EpiPen. I will do some research on it too...
I am glad you are alright! Scary stuff...
