Details +

O2B Sinus Health combines eight herbs in one comprehensive liquid formula.

Peppermint and licorice contribute to the formula’s soothing herbal and taste profile.

Echinacea is included to support normal immune-system function.

Eyebright, ginger and horseradish are traditionally used in herbal formulas developed for sinus and upper-respiratory support.

Golden rod and barberry complete the blend, providing support for the body's response to seasonal immune stress and the tissues commonly affected during infections

The liquid format allows the serving to be measured according to the label and taken either neat or in warm water. This may be particularly useful for those who prefer liquid herbs to tablets or capsules.

FAQs +

What is O2B Sinus Health used for?

O2B Sinus Health is designed to support clear sinuses, comfortable nasal breathing, the upper respiratory system, immune function and natural mucus drainage from the sinus cavities.

How much should adults take?

Adults take 5–10ml neat or mixed into warm water, up to six times daily, or as directed by a healthcare professional.

Can I mix it into water?

Yes. The serving can be mixed into warm water or taken neat.

Can children take O2B Sinus Health?

Provide a half-adult serving for children over five years.

Do not give it to a child under five unless specifically advised by a qualified healthcare professional. The product is not recommended for infants.

Can I take it during pregnancy or breastfeeding?

No. O2B Sinus Health should not be taken during pregnancy or breastfeeding.

Can I take it with prescription medication?

Consult your healthcare professional or pharmacist before combining this multi-herb formula with prescription medicine.

Licorice in particular can affect blood pressure and potassium balance and may interact with diuretics and corticosteroids. Other herbal ingredients may also have medicine interactions depending on your treatment.

Can I take it if I have high blood pressure?

Speak with your healthcare professional before use. Licorice can raise blood pressure or affect potassium levels in susceptible people, particularly with frequent or prolonged intake.

Can I use O2B Sinus Health every day?

Because the formula contains licorice and several active herbs, consult a healthcare professional before frequent or extended use, especially if you take medication or manage a health condition.

Does O2B Sinus Health treat a sinus infection?

No. It is a liquid herbal product intended to support sinus, upper-respiratory and immune function. It should not be presented as treating an infection or replacing medical care.

Acute sinus symptoms are commonly associated with viral illness, but other causes are possible. Seek healthcare advice if symptoms are severe, persist or worsen.

What else can I do when my nose feels congested?

Rest, maintain hydration and consider a saline nasal spray or rinse. A warm face pack may also feel soothing.

Use only sterile water or water that has been boiled and cooled when preparing a nasal rinse. Do not use untreated tap water.

What is the difference between O2B Sinus Health and O2B Nasal Clear?

O2B Sinus Health is an oral liquid herbal formula taken neat or in warm water.

O2B Nasal Clear is an external herbal balm applied to support healthy sinuses and clear nasal breathing.

What is the difference between O2B Sinus Health and O2B Allergies?

O2B Sinus Health is an eight-herb oral liquid focused on sinus support, the upper respiratory system and natural mucus drainage.

O2B Allergies is a convenient under-the-tongue liquid spray formulated around the body’s normal response to environmental allergens.

What should I do if my symptoms keep returning?

Recurring nasal or sinus symptoms may have several possible causes, including environmental allergies, chronic sinus inflammation or structural issues. Speak with a healthcare provider rather than relying solely on repeated self-treatment.

Who is Sinus Health for?

When your nose does not feel clear, even ordinary parts of the day can become challenging. Sleep may be interrupted, concentrating can feel more difficult, and exercising or getting through a busy workday may involve far more mouth-breathing than you would like.

O2B Sinus Health may suit:

Adults whose sinuses feel challenged during seasonal changes
People wanting support when cold weather, dry indoor air, dust or environmental irritants affect nasal comfort
Those wanting support for clear nasal breathing and normal mucus drainage
People who feel that sinus congestion disrupts sleep, concentration or daily activity
People who prefer liquid herbs to swallowing several capsules

Why take Sinus Health?

Sinus discomfort rarely waits for a convenient time.

It may show up on the night you need a proper sleep, during a busy week at work, before a flight or when the whole household seems to be passing something around. You may find yourself repeatedly reaching for tissues, waking with a dry mouth or struggling to feel properly refreshed because nasal breathing has not felt comfortable.

At those times, managing several separate herbal products may be the last thing you want to organise.

O2B Sinus Health brings eight herbs together in one liquid formula so that your routine can remain straightforward.

How to take O2B Sinus Health

Take 5–10ml, either neat or mixed into warm water, up to six times daily or as directed by your healthcare professional.

Sinus h ealth

Bouight a 200ml bottle (didn't get offered a smaller size) on 15th November... Once again I know there is no guarantee. I followed instructions on the bottle using it 2-3 times a day for 3 days. Absolutely no improvement at all. Most disappointed - very expensive visit to O2B that day! Bought 3 items and the only one that worked was a moisturiser that I have used for a couple of years!!!
