Because this was brought up in the daily email I decided to try it for strengthening my lungs after a few weeks of coughing.
I did not get to it until moon light so the pictures are flash which is not so clear.
I picked some leaves from the patch where I dug Himalaya's after the mullen had seeded.
The fuzzy leaves are the favorite of the weaver
bees which gather the fuzz to plug their nest cavities.
I put the cleaned leaves in boiling water with a potato masher to hold them under the water and turned the heat off to let them steep.
Will see how it works and report back.
