- Gumweed is a traditional medicine of California Native Americans, such as the Chumash people. Gumweed was used clinically from the 1880s until 1960 in the United States and the United Kingdom for the treatment of asthma, bronchitis, and poison ivy rash. Gumweed use in clinics was discontinued in 1960 when a new law required medicines to have proven efficacy in clinical trials. The plant contains grindelane diterpenoids of unknown pharmacological activity.
- High quality trials supporting the use of gumweed for asthma, bronchitis, dermatitis, or any other condition are currently lacking. High quality clinical trials of gumweed are needed in these areas.
