Antihistamines are used to treat seasonal allergies. Also known as Hay fever. Many people use antihistamine medication, but there are also natural antihistamines.
Seasonal allergies can cause symptoms like sneezing and itchy eyes.
How Do Antihistamines Work?
An abnormal immune-system response can cause allergies. Your immune system mistakenly considers an allergen a threat when it comes in contact with something you are allergic to. It releases histamine as part of its defence against that perceived threat.
Histamine helps fight invaders like parasites. Your immune system reacts negatively to harmless substances when you have allergies. This is what causes allergy symptoms.
Antihistamines prevent histamine from having an effect. This prevents histamine from causing allergies and the inflammation tied to the histamine reaction.
Several natural substances contain antihistamines. Although research on their safety or effectiveness is still in its infancy, some preliminary results are encouraging.
A review of herbal medicine for inflammation conditions found that they are safer, more effective and more appealing than drugs made in the lab.
You might be familiar with vitamin Vitamin C’s benefits in reducing the severity and duration of colds. However, it is also an anti-inflammatory and antioxidant. Research has shown that allergies can be caused by inflammation or oxidative stress, which is an imbalance in free radicals.
Researchers found that high intravenous vitamin C levels improved allergy symptoms. The researchers also discovered evidence that vitamin C deficiencies may cause allergies.
Quercetin, an antioxidant found in many plants, appears to have anti-allergy as well as antihistamine properties. One study found quercetin may suppress an allergic gene.
Quercetin can cause side effects such as headaches or stomach upsets. Before you take quercetin, talk to your doctor.
Butterbur (Petasites hybridus) is a shrub which is native to Europe, Asia and parts of North America. It has been used medicinally in some form since the Middle Ages.
Butterbur can be purchased in extract, pill, and dried form. Some butterbur sold in commercial quantities contains chemicals known as pyrrolizidinealkaloids (PAs). The liver, lungs and blood circulation can be damaged by PAs.
Bromelain is one of several enzymes found in pineapples, Ananas comosus. These are grown in subtropical and tropical parts of the globe. It was used historically as a medicinal ingredient in South America and Central America.
Although not all studies agree on this, evidence suggests that bromelain may be an anti-inflammatory agent and help with nasal congestion. Bromelain was found to penetrate the sinus mucous membranes. This could make it useful in treating allergies.
