Allergic rhinitis, a type of allergy that affects the eyes and nasal passages, is characterized by sneezing, itchy eyes and a runny nose. It is caused by inhaling allergens such as pet dander, pollen and dust. Some people suffer from allergic rhinitis all year round, while others may experience seasonal allergic rhinitis, also known as hay fever. The best way to prevent allergic rhinitis is to avoid exposure to allergens, notes MedlinePlus. However, antihistamines and nasal decongestants are often used to provide relief. A number of herbs may also help alleviate symptoms, but there is little scientific evidence to prove they work. Talk to your health care provider before using herbs to treat allergic rhinitis.
Butterbur
According to the results of a randomized, double-blind trial published in the "British Medical Journal," the herb butterbur is as effective as cetirizine, a commonly used antihistamine, in relieving symptoms of seasonal allergic rhinitis. The study suggests that butterbur may be considered as a potential treatment for allergic rhinitis, especially by patients who dislike the sedative effects of antihistamines. Butterbur may cause side effects, including stomach upset and headache, notes the Department of Health and Human Service's National Toxicology Program. Do not use this herb if you are taking anticholinergic drugs, as it may heighten their effects.
Stinging Nettle
The University of Maryland Medical Center notes that stinging nettle may help relieve symptoms of allergic rhinitis, although clinical studies to prove this are lacking. Stinging nettle, also known as urtica dioica, may work by reducing histamine levels in the body. It can be taken as tea or as a dietary supplement. Although stinging nettle is considered safe, it may occasionally cause fluid retention and stomach upset. Do not take this herb if you are pregnant, as it can cause miscarriage. Stinging nettle may heighten the effects of certain drugs including anticoagulants, diuretics and non-steroidal anti-inflammatory drugs.
Goldenseal
Some herbal treatments for allergic rhinitis contain an herb known as goldenseal. However, the National Center for Complementary and Alternative Medicine notes that there is no scientific evidence to prove that it is effective for any medical condition. It may be taken as a tea, in capsules or tablets and is considered safe for most adults; however, it should not be used by infants or young children. Goldenseal may cause nausea and vomiting in rare cases.
