Hay Fever
Butterbur
Studies have shown butterbur extract to be effective at reducing hay fever symptoms.Dose:
1 tablet standardized to contain 8 mg petasin extract two to three times a day for two weeksButterburTwo double-blind studies have compared butterbur extract to standard antihistamine drugs in people with hay fever. The first compared it with the drug cetirizine (Zyrtec) and found the drug and butterbur extract relieved symptoms equally well. However, cetirizine caused significantly more adverse effects, including a high rate of drowsiness.1 The second study compared butterbur extract with fexofenadine (Allegra) and placebo. Butterbur extract was as effective as fexofenadine at relieving symptoms, and both were significantly better than placebo.2
People with hay fever had better symptomatic relief and reductions in levels of immune cells associated with allergic reactions (eosinophils) when treated with an herbal formula containing horny goat weed compared with a formula without horny goat weed and another herb by itself.3 Traditionally 5 grams (1 tsp) of horny goat weed is taken three times per day, usually after being simmered (decocted) in 250 ml (1 pint) of water for 10 to 15 minutes.4
In a double-blind study, an extract of the butterbur plant (Petasites hybridus) was significantly more effective than a placebo at improving symptoms in people suffering from seasonal allergic rhinitis.5 The study used a preparation standardized to contain 8 mg of total petasin per tablet. One tablet was administered either two or three times a day for two weeks; the larger amount was found to be more effective than the smaller amount.
Guduchi
In one trial, an extract of Tinospora cordifolia effectively relieved symptoms of allergic rhinitis, including sneezing, runny nose, nasal obstruction, and nasal itching.Dose:
300 mg of a standardized extract three times a dayGuduchiTinospora cordifolia is an herb used in traditional Indian (Ayurvedic) medicine for increasing longevity, promoting intelligence, and improving memory and immune function. In a double-blind trial, an extract of Tinospora cordifolia was significantly more effective than a placebo at relieving symptoms of allergic rhinitis, including sneezing, runny nose, nasal obstruction, and nasal itching. The study used 300 mg of a standardized extract three times a day for eight weeks.6
Horny Goat Weed
Horny goat weed has been shown to relieve hay fever symptoms.Dose:

Probiotics
In one trial, supplementing with Bifidobacterium longum strain BB536 during the pollen season significantly decreased symptoms such as sneezing, runny nose, nasal blockage.Dose:
Refer to label instructionsProbioticsIn a double-blind trial, supplementation with a specific probiotic strain (Bifidobacterium longum strain BB536) during the pollen season significantly decreased symptoms such as sneezing, runny nose, nasal blockage, compared with a placebo.9
Thymus Extracts
A thymus extract known as Thymomodulin has been shown in studies to improve the symptoms of hay fever and allergic rhinitis.Dose:
120 mg daily purified thymus polypeptidesThymus ExtractsThe oral administration of a thymus extract known as Thymomodulin has been shown in preliminary studies and double-blind trials to improve the symptoms of hay fever and allergic rhinitis.10,11,12 Presumably this clinical improvement is the result of restoration of proper control over immune function.
Vitamin E
In a study of people with hay fever, adding vitamin E to regular anti-allergy treatment during the pollen season significantly reduced the severity of hay fever symptoms.Dose:
800 IU dailyVitamin EIn a double-blind trial, supplementation with a specific probiotic strain (Bifidobacterium longum strain BB536) during the pollen season significantly decreased symptoms such as sneezing, runny nose, nasal blockage, compared with a placebo.13
Nettle
Taking nettle leaf may ease symptoms, including sneezing and itchy eyes.Dose:
0.5 to 8 grams dailyNettleIn an isolated double-blind trial, nettle leaf led to a slight reduction in symptoms of hay fever—including sneezing and itchy eyes.14 However, no other research has investigated this relationship. Despite the lack of adequate scientific support, some doctors suggest taking 450 mg of nettle leaf capsules or tablets two to three times per day, or a 2–4 ml tincture three times per day for people suffering from hay fever.
Quercetin
Quercetin is an increasingly popular treatment for hay fever.Dose:
Consult a qualified healthcare practitionerQuercetinQuercetin is an increasingly popular treatment for hay fever even though only limited preliminary clinical research has suggested that it is beneficial to hay fever sufferers.15

Tylophora
Tylophora contains compounds that have been reported to interfere with the action of mast cells, which contribute to itchy eyes, runny nose, and chest tightness.Dose:
Spray a lotion containing 3.7% citronella in a slow-release formula every morning for six days per weekTylophoraTylophora is an herb used by Ayurvedic doctors in India to treat people with allergies. It contains compounds that have been reported to interfere with the action of mast cells, which are key components in the process of inflammation responsible for most hay fever symptoms.17 Mast cells are found in airways of the lungs (among other parts of the body). When mast cells are activated by pollen or other allergens, they release the chemical histamine, which in turn leads to a wide number of symptoms familiar to hay fever sufferers—itchy eyes, runny nose, and chest tightness. Ayurvedic doctors sometimes recommend 200–400 mg of the dried herb daily or 1–2 ml of the tincture per day for up to two weeks.
Vitamin C
Vitamin C has antihistamine activity, and supplementing with it has been reported to help people with hay fever.Dose:
Refer to label instructionsVitamin CAlthough vitamin C has antihistamine activity, and supplementation, in preliminary research,18,19 has been reported to help people with hay fever, 2,000 mg of vitamin C per day did not reduce hay fever symptoms in a placebo controlled trial.20 Thus, while some doctors recommend that hay fever sufferers take 1,000–3,000 mg of vitamin C per day, supportive evidence remains weak.
