For several years now, I have been pulling up Swallowwart by the roots and burning it. And, this year, even though I was wearing gloves, I broke out in an itchie rash on my legs, feet, hands and arms.....not that it came from that, but the problem appeared after touching the Swallowwart. Other than pulling it up by the roots, is there anything else individuals can do to get rid of it ?
