Oil of Oregano & Cold Prevention

Many alternative health insiders say there is a cure for the common cold. However, this secret weapon to keep you healthy during cold season packs a perhaps too-powerful punch. Literature about oil of oregano expounds on its healing potential while stressing caution in its use.

Where to get it

• You can purchase oil of oregano from most natural health stores, or from an online vendor of alternative health products. Since this substance packs a wallop, expect to pay a lot for a small amount--typically at least $15 for less than half an ounce. You'll be taking tiny doses, so a small bottle should suffice. Don't try to make your own oil of oregano from the dried green stuff you throw on your pizza. The common kitchen herb is an entirely different plant--origanum marjorum--than the powerful essential oil--origanum vulgare.

How to take it

• Natural health experts differ on whether it is advisable merely to inhale the oil or take it internally. They agree however, the oil must always be diluted. Try placing three or four drops of the oil in a carrier such as olive, sesame, or coconut oil for inhalation. If you want to try it orally, take no more than three drops in a full glass of juice or tea. Do not use oil of oregano in an aromatherapy bath as it should not come into contact with soft tissues. Oil of oregano works best when taken as a preventive measure at the earliest hint of a cold.

Precautions and side effects

• Pregnant and nursing women should avoid taking oil of oregano, as should people with allergies to mint, thyme, basil, or sage. Children should never take this product orally and should only receive very small doses through inhalation. Oil of oregano can interfere with the body's ability to absorb iron so long-term use is discouraged. Reported side effects include dizziness, nausea, headaches, and fatigue.
