I took Burdock for a while about 25 years ago. I was x-rayed on my feet due to difficulty walking and intense pain in my heels. It was found that each heel had several spurs and they wanted to do surgery. I refused at that time, so a person very knowedgeable about herbs suggested I should try Burdock caps instead. In about 3 days the pain had lessened, and walking wasn't quite as difficult. In 2-2 1/2 weeks the pain was completely gone! I recommended the Burdock Root to a co-worker for her spurs and it worked for her too. She cancelled her scheduled surgery and has been fine ever since!
