Dear Father Mark - Oregano oil is a remedy for so many ailments and injuries. Generally speaking it can be rubbed on the skin full strength or diluted depending on the location and the sensitivity of the person using the product. Areas to avoid for full strength would typically be the face and private areas of the body but full strength for some may need to be avoided all together. Oregano oil can also be ingested with a few drops in a glass of water with the quantity of water depending on preference or full strength in a gel capsule. The number of drops placed in water or in a capsule would depend on the seriousness of the ailment and also the fortitude of the individual and their tolerance level for strong remedies. As for ailments and injuries for which oregano oil may be used please reference our website at www.oreganoworld.com. Thank you for the inquiry.

Dear Audrey,

If you do a google search under "post nasal drip oregano oil", you will have an opportunity to read endless testimonies regarding the efficacy of oregano oil for your ailment and the method of treatment. Some of the more popular ways people use oregano oil are as follows: Drinking water mixed with a few drops of oregano as often as necessary. Using a dropper to place one to ten drops in a gel cap and immediately ingesting it with plenty of water. Oregano oil is potent and will dissolve the gel cap if left to sit too long. Most people start with a drop or two and work their way up to determine what they can tolerate. Placing a few drops in a steam inhaler or a pan of gently steaming water and inhaling it through the nose and/or mouth. Almond milk or any dairy product will counteract the burning effects of oregano oil if it happens to come in contact with a sensitive area within or on your body or if the dose is too strong.

Hopefully this helps, Gary Greenfield
