A sinus is a membranous cavity present in the bones of the nose, eyes, and cheeks. The membranes function as a filter for germs by producing mucus. Sometimes, these cavities can become clogged or congested, causing an inflammatory response. This can cause pain in your forehead and along your cheeks and nose.

In most cases, sinusitis (inflammation in the sinus cavity) is caused by a viral infection in the upper respiratory tract, while in rare cases, it may be caused by a bacterial infection (3).

Traditional Chinese medicine used herbal and acupuncture therapies to treat sinus infections. Herbal medications like magnolia flower, Angelica root, xanthium powder, and peppermint were used.

There are many natural remedies and methods that one can adopt to treat sinus infection. Antibiotics, decongestant nasal sprays, steroidal nasal sprays, nasal rinse, etc. are some of the treatments used. However, these medications have certain drawbacks:
  • These options can only be used for a short period of time and may not tackle the root cause of the infection (4).
  • People are more likely to become immune to these treatments, making them less viable.

However, some studies suggest that using hydrogen peroxide solution can help clear sinus infection. Let us see how it can be used for this.

Here’s why hydrogen peroxide is ideal for treating sinus infection:

1. Can Relieve Congestion

Studies show that hydrogen peroxide can help clear the affected matter from the sinus cavity and hence clear the congestion (2).

2. Can Get Rid Of Infection

Hydrogen peroxide has antibacterial properties (5). The oxygen released from hydrogen peroxide can help in eliminating the microbial infection.

3. Prevents Re-Infection

Rinsing your sinus cavity with an antiseptic like hydrogen peroxide can prevent germs from re-infecting the damaged areas, thus giving your nasal membranes the time to heal. When the nasal membranes are in good health, they are more capable of resisting infection.

4. Is Economical

It is cost-effective as compared to other treatment methods. One bottle of hydrogen peroxide can be used multiple times.

5. Non-Addictive

Many other treatments, like steroidal nasal sprays, can be addictive and can cause the body to become tolerant. This means that you might progressively need a higher dosage as time passes to get the same effect. Hydrogen peroxide does not make your body dependent or addicted to it.
