Natural Products

Saline Nasal Irrigation

There is some evidence to suggest that saline nasal irrigation may modestly improve some seasonal allergy symptoms.

Butterbur (Petasites hybridus)

There is some evidence that butterbur extract can decrease the symptoms associated with seasonal allergies.

Honey

There is no convincing scientific evidence that honey relieves seasonal allergies.

Mind and Body Practices

Acupuncture

There are data from some randomized controlled trials that suggests that acupuncture may improve some symptoms of allergic rhinitis, as well as quality of life.

Other Approaches

Probiotics

There is some limited evidence that suggests that probiotics may improve some symptoms, as well as quality of life, in patients with allergic rhinitis, but overall the data on probiotics and allergic rhinitis is inconsistent and effects may vary from one probiotic formulation to another.
