Respiratory Defense is a dietary supplement based on herbs that is recommended for strengthening the functioning of the immune system, as well as for the treatment of respiratory infections. The company behind the product is Gaia Herbs.

Gaia Herbs is a producer of herbal remedies from the United States. It is one of the most important players on the market for herbal remedies based on organic herbs or plants harvested using an environmentally friendly technology. Its portfolio of products includes an array of remedies against daily stress, common cold symptoms, liver function, and other health concerns.

The producer advertises Respiratory Defense as effective in maintaining healthy mucus membranes thereby being able to prevent cold and flu symptoms and respiratory upper tract infections in general. In addition, the liquid filled capsules also contain Echinacea extracts. This plant is very useful in maintaining a well functioning immune system according to traditional medicine and healthcare specialists. This is a very potent drug, as one capsule has 850 mg of crude herb. It also acts quickly, as the capsules disintegrate rapidly in the stomach. Respiratory Defense is supposed to help people that have weaker immune systems and those that are more prone to catching a cold.

Respiratory Defense includes the following ingredients: Osha Root (Ligusticum porteri), Echinacea Purpurea Aerial Parts (Echinacea purpurea), Echinacea Purpurea Seed (Echinacea purpurea), Echinacea Purpurea Root (Echinacea purpurea), Echinacea Angustifolia Root (Echinacea angustifolia), Grindelia Floral Buds (Grindelia robusta), Oregano Leaf (Origanum vulgare), Irish Moss Fronds (Chondrus crispus), Hyssop Flowers (Hyssopus officinalis), Lobelia Herb & Seed (Lobelia inflata), Barberry Root Bark (Berberis vulgaris), Goldenseal rhizome (Hydrastis canadensis), Mullein leaf (Verbascum spp.), Oregon Grape Root (Mahonia aquifolium), St. John’s Wort Flower Buds (Hypericum perforatum), Vegetable Glycerin, and Vegetable cellulose (capsule).

Product Features

Respiratory Defense is a formula based on osha root, grindelia and hyssop, which support the respiratory system, and on goldenseal, Echinacea and oregano, all of which promote a healthy immune system response. Osha root is a plant used by the Native Americans and the Chinese in treating respiratory infections. The Native Americans also used it for digestive disorders and muscle pains. The herb is effective in treating productive as well as dry coughs according to some herbalists. Laboratory tests have shown osha root possesses anti-viral and anti-microbial benefits but further clinical trials still need to be done. Osha root can cause contractions of soft muscles such as the uterus therefore it is not recommended to pregnant women because it may induce contractions. It should also not be used by breastfeeding mothers.

The Respiratory Defense formulation has not been evaluated by the FDA since this is promoted as a dietary supplement. Hence its effectiveness and safety cannot be guaranteed. The manufacturer does not mention any side effects though. It only states that the product should not be used by pregnant or lactating women. In addition, medical advice is required in case you suffer from a medical condition or are currently taking any other medication.

The product comes in bottles of 60 capsules. Gaia Herbs recommends one capsule three or four times daily. Consequently one bottle is enough for half a month to 20 days maximum.
