Ragweed has a bad reputation for its pollen being a major, if not primary, contributor to hay fever. Ray takes the optimistic view of this correlation: he thinks of this effect as ragweed taking a symptom out of our body—a symptom that is already living in the body and is generally manifested in our mucus. Ragweed is just helping us get well!
John described ragweed as an aid for sexually transmitted diseases (STD’s), applied as a wash depending on the disease. Many Native Americans, however, used the leaves of ragweed for a variety of external ailments. The Cherokee applied the crushed leaves on hives and stings while the Delaware used this poultice to prevent blood poisoning. The Lakota used a wash of the leaves for treating swellings and the Mahuna used this wash for minor skin and scalp diseases.
