What is it

British elecampane (Inula britannica) is a flowering plant whose flowers are used in traditional Chinese and folk medicine, where the dried flower is known as xuan fu hua. Its studied constituents are sesquiterpene lactones with anti-inflammatory activity in the laboratory, but it has essentially no clinical evidence as a dietary supplement.

anti-inflammatory activity

Mechanism only
Mixed

Sesquiterpene lactones isolated from Inula britannica suppress inflammatory signaling such as NF-kB in cell and animal models, consistent with its traditional use for cough and inflammatory complaints. There are no controlled human trials, so any clinical anti-inflammatory benefit is unproven.

Effect size: Not established in humans
Time to effect: Not characterized
Best fit: not defined by clinical data

Bottom line: Anti-inflammatory in the lab, but with no human evidence it remains a traditional remedy only.

How to take it
