Often used as a relaxant as Peppermint contains menthol and volatile oils that soothe inflammation of mucous membranes, relax muscles in the body and enables the release of mucous. Soothing and calming, it dramatically improves nasal breathing, lowers blood pressure and reduces cardiac output.

Licorice Root:
Medicinal use of this root in both Eastern and Western cultures dates back thousands of years. It is a potent anti-inflammatory herb that is soothing and softens mucus membranes of the sinus cavities, throat and lungs. It also has a significant anti-allergic activity that strengthens the immune system, by counteracting the negative effect of cortisol and allows the body to form antibodies to allergens. Due to this action, Licorice has long been prescribed for Asthma and rhinitis.

Classed as an immune stimulant, anti-inflammatory, anti-bacterial, anti-viral, anti-fungal and cell normalizer that has long been used to treat infections, respiratory disorders, skin conditions and arthritis. It has the unique ability to help regulate the immune used to treat infections, respiratory disorders, skin conditions and arthritis. It has the unique ability to help regulate the immune system and shock it into action. With a long history of use, Echinacea (purple coneflower) has been proven effective in treating many conditions and pathogens. There are many different pharmacological components found in Echinacea including potent flavonoids, essential oils, caffeic acid derivatives and polysaccharides. All of which actively elevate white blood cell levels and their activity when needed to fight infections from bacteria, viruses and fungi such as Candida Albicans. These immune enhancing abilities also have effects on tumor cells. With clinical studies support these activities, Echinacea is prescribed by medicinal herbalists to treat infections such as colds, flu, upper respiratory tract infections, urinary tract infections, vaginal thrush and other infectious conditions.

Eyebright (Euphrasia officinialis) has been prescribed since the 14th century by herbalists to treat inflammatory conditions. Eyebright has astringent compounds known as tannins, which work to tighten the top layers of the mucus membranes, reducing mucus secretion, which in turn reduces irritation. It also has anti-inflammatory components including glycosides and flavonoid antioxidants properties and is useful where there is watery nasal discharge, as seen in rhinitis, colds and flu’s. With high levels of antibacterial, antiviral and antifungal properties, Eyebright is also useful in boosting the immune system to combat infections.

Ginger root is renowned for its warming effect and enhancing circulation through the body. Ginger root is rich in volatile oils, B Vitamins, Vitamins A and c, essential fatty acids, amino acids, beta-carotene and is a vast source of minerals including iron, potassium, magnesium, selenium, zinc, phosphorus and volatile oils. Long been prescribed for arthritic conditions, digestive disorders, boosting the immune system, supporting the cardiovascular system and blood circulation.

Horseradish contains biologically active volatile organo-sulfur containing compounds that have potent anti-inflammatory, diuretic and nerve soothing effects. Horseradish root also has compounds allyl isothiocyanate and sinigrin which have been found to have powerful antioxidant, immune stimulating and detoxification functions. Other health benefits include stimulatory effects on the secretion of salivary, gastric, and intestinal digestive enzymes, and thereby it supports and aids digestion. Other biologically active compounds in horseradish include good amounts of vitamins B2, B3, B5, B6, C and folic acid, potassium, manganese, iron, copper, zinc and magnesium. Horseradish was traditionally prescribed in herbal medicine for stimulating appetite, treating bronchitis, colds, coughs, fluid retention and kidney stones, gout and urinary tract problems. Modern science now highlights that Horseradish has potent antioxidant properties that inhibit cancer cell growth in vitro and actively stimulates that production of immune supporting antibodies, including leukocytes and phagocytes helping to make Horseradish a powerful antimicrobial ingredient in O2B Sinus Health.

Golden Rod:

Golden Rod has diuretic, astringent, anti-inflammatory, antiseptic and expectorant qualities and is included here in O2B Sinus Health to relieve symptoms associated with the common cold, flu and infections of the respiratory tract.

I used to wake up with headachesReview by Leane
Really good for taking before bed to clear sinuses and prevents me from snoring due to congestion. I used to wake up with headaches- I can now prevent this by taking sinus health during the night if I wake up snoring. (Posted on 12/01/2020)
