Hay fever, or seasonal allergic rhinitis, is a harmless but annoying condition characterized by symptoms that include sneezing, inflamed itchy eyes and a runny nose. It occurs in response to an inhaled trigger, usually grass or tree pollen. The best way of avoiding hay fever is to limit your exposure to allergens, but antihistamines and nasal corticosteroids can help to relieve existing symptoms. Some herbs may also help to relieve hay fever symptoms, although scientific evidence to prove they work is limited. Get medical advice before using herbal remedies to treat hay fever as they may cause side effects or interact with medicines you may be taking.
Stinging Nettle
Stinging nettle may be helpful for hay fever, according to the University of Maryland Medical Center. Studies to show that it is effective are lacking, but an article published in the July 2009 issue of "Phytotherapy Research" notes that bio-active compounds found in this herb may inhibit pro-inflammatory pathways. Stinging nettle is likely safe, notes RxList, but side effects may include stomach upset and increased sweating. Avoid this herb if you pregnant or breastfeeding or you if have diabetes or a kidney disorder. Stinging nettle may interact with other medicines including lithium and anti-hypertensive drugs. Get medical clearance before taking it.
Butterbur
The results of a clinical trial published in the January 2002 issue of the "British Medical Journal" show that butterbur may be as effective as the antihistamine cetirizine in relieving hay fever symptoms. The study's lead author, A. Schpowal, adds that butterbur should be considered as a potential hay fever treatment for people who wish to avoid the sedative effects of antihistamines. This herb may cause a hypersensitivity reaction in some people and should be avoided if you have liver disease as it may cause hepatoxicity.
Goldenseal
Goldenseal may have immune-enhancing effects and may help to alleviate hay fever symptoms, UMMC notes. However, clinical evidence to show that it is effective is lacking. MedlinePlus states that taking a single goldenseal is likely safe, but it is unclear whether long-term use of this herb is safe. Do not use goldenseal if you are pregnant or breastfeeding. It may interact with other medications including cyclosporine and drugs that are modified by the liver. Get medical advice before using this herb.
