Dr. Christopher loved Lobelia Best and wrote the most pages.
He liked black and blue cohosh for his B&B formula
Some how or another an amish man years ago started selling amish farmers a blend of Lobelia and black cohosh to their horses.
I assume it helps with lung health, but not sure what their logic is.
For some years I have been making it for them and it continues to become larger orders. NORMALLY nothing grows in size over time--unless it works; because often the old order amish make very little $$$ and they will not buy anything unless they need to.
SO MUCH has been lost or destroyed with herbal medicines and it only becomes worse with the computer age.
