Here is a list of the most accessible and reliable antihistamine herbs:
Basil (Ocimum sanctum)– One of the best antihistamine herbs, basil has a history in helping prevent stomach cramps, gas, and constipation. A poultice of Basil leaves can can work as an antihistamine to draw out insect, bee wasp, or snake venom. It helps alleviate acne, heal abrasions and speeds healing when used on cuts.
Caraway Seed Essential Oil– has antihistamine and antimicrobial properties and is very effective in treating mild allergic reactions.
Chamomile (Matricaria chamomilla)– is rich in antihistamine properties and is one of the most effective antihistamine herbs. The flowers can be crushed and used as a poultice for inflammatory swelling. Chamomile can cause histaminic allergic reactions in some very sensitive people. If this occurs, simply discontinue.
Clove Essential Oil– has antihistamine properties. This essential oil is helpful in the treatment of dermatitis due to allergic reactions. Clove EO is not safe for children under 10, however.
Echinacea (Echinacea purpurea)– Echinacea is a widely used herbal remedy for treatment of upper respiratory tract infections. This purple coneflower has shown to have antihistamine properties and is counted among some of the more popular antihistamine herbs.
Eyebright and Elder also have a reputation for use as hay fever remedies. However, an individual allergic to one of these plants should avoid them unless under the care of a doctor of natural medicine.
Fennel (Foeniculum vulgare)– In Chinese herbal practice, fennel is used for indigestion, spasms in the digestive tract, as well as expelling phlegm from the lungs. Fennel is rich with the antioxidant flavonoid “quercetin”. Quercetin is a strong natural antihistamine shown to be very helpful for allergies and histamine-related inflammation.
Ginger (Zingiber officinale)– another classic herb in the Chinese Materia Medica, ginger works well on allergic reactions such as hives and wheals.
Jewelweed (Impatiens aurea)– contains a compound called “lawsone” that treats uticaria. Jewelweed is used as a natural remedy for poison ivy, poison oak, okra spines, stinging nettle and acne treatment. Jewelweed is also used for heat rash, ringworm and many other skin disorders, as well as bug bites and razor burn.
Lemon balm (also known as Melissa)– has antihistamine action and is useful to treat eczema and headaches. This essential oil has antihistamine properties and helps with allergies.
Papaya (Carica papaya)- Some may be surprised that papaya is counted among natural antihistamine herbs, but papaya does indeed inhibit the secretion of histamine. Papaya juice can be taken internally as well as applied topically to diffuse a histamine attack.
Parsley (Petroselinum crispum)– Testing shows Parsley’s antihistamine action which may be helpful for those with hay fever or hives.
Reishi (Ganoderma lucidum)– Hailed the “mushroom of immortality”, (Ling Zhi in Chinese). Japanese researchers have found that reishi acts as an antihistamine, making it useful for treating allergies. “Lanostan”, a compound found in reishi, appears to control the release of transmitting chemicals in the body, thereby inhibiting the release of histamine. Since reishi also promotes the adrenal function and immune reaction, it has added effectiveness in controlling the body’s reaction to an allergen.
Stinging Nettle (Urtica dioica)– The very same plant that will produce hives if its hairs inject their histamine into you can also work as one of the best antihistamine herbs to heal the problem. The plant does not contain enough histamine to cause a problem when taken orally. Tea can be made from the leaves or cooked as greens. The stinging hairs lose their sting when the plant is cooked. We use this in our seasonal allergy formula!
Thyme (Thymus vulgaris)– is a natural antihistamine, as well as having antiseptic properties to help purge infections. The essential oil has been shown to have antimicrobial activity against a host of different bacteria and fungi.
Wild Oregano (Origanum vulgare)– aka Wild Marjoram, is one of the very best antihistamine herbs as it has at least seven different antihistaminic chemicals, therefore fights allergies as well as fungus and infection.
