Aqueous extract of sunflower seeds reduces lung inflammation – a safe, simple treatment for asthma?
Asthma is a serious and sometimes life threatening condition. It is also extremely common. Good treatments exist, but standard treatments are sometimes unable to offer adequate control. As a result, asthma is one of the most common reason for an emergency room visit, the most common reason for absence among school aged children and a leading overall cause of diminished quality of life. The incidence of asthma is increasing globally.
A simple, inexpensive, effective treatment for asthma would be welcome – especially one relatively free from side effects and perhaps entirely free from serious side effects. Sunflower seeds appear attractive from many perspectives, not least of all because the reduction in inflammation observed is unlikely restricted to lungs and asthma. It’s likely that sunflower seeds reduce inflammation generally.
The researchers whose publication is cited below conclude that further work is required to identify the specific factors responsible for the reduction in inflammation – and reduction in asthma symptoms – they observed. Or perhaps we could simply use an aqueous extract of sunflower seeds – since that appears to be both safe and effective.

Molecular inflammation is a pivotal process in various degenerative immune diseases, including asthma and atopic dermatitis.
In this study, we examined the effects of Helianthus annuus seed (HAS) aqueous extract on an in vivo anti-asthmatic model. The levels of IL-4/IL-13 cytokines and IgE were determined.
HAS extract induced a decrease in CD4+ cell number, IL-4/IL-13 expression, and IgE secretion levels in the lungs. Our findings collectively suggest that the HAS extract has considerable potential in reducing the asthma-like symptoms.
However, further isolation and purification of the extract is required to determine the specific factor(s) responsible for its anti-asthmatic activity.
