It's a pretty useful spot. Located in between the bowel and the anus, it is of course wonderfully useful for expelling feces. But because it is a highly vascularized area of tissue, it is also very useful for absorbing things into the blood. Rectal suppositories of medicine have been used for centuries, and more recently it's come to my attention that essential oils can be administered systemically via this technique.
Although inhaling essential oils has certainly improved my disease symptoms and has helped me maintain a higher lung capacity, the route of inhalation seems somewhat limited in that it only reduces infection in those areas that can be reached by the aerosolized solution. This means that those areas with the most amount of infection and mucus plugging (i.e. the small airways at the distal regions of the lungs) are still left untouched by antimicrobials. Thus, it was suggested to me by multiple sources that I should try another route of essential oil administration that would facilitate the deliverance of essential oils to those smaller airways: rectal suppositories.
Although this technique is relatively unknown in the U.S., it is more widely used in Europe. Administering essential oils via the rectum allows the oils to be quickly and easily absorbed into the blood stream via the highly vascularized tissue in the rectum and circulates the compounds throughout the body first before being filtered by the liver and kidneys . This is an especially effective route of administration for respiratory and gastrointestinal infections. This technique appealed to me because it seemed to be the treatment route most similar to the administration of IV antibiotics, the most powerful tool for combating CF lung infections.
So It Begins
I worked with a certified aromatherapist to make the suppositories for me . The first 10-day course consisted of a formula of five oils mixed in a base of cocoa butter, with approximately 5 drops of essential oils per suppository. We used thyme (chemotype thymol), rosemary (chemotype camphor), Eucalyptus citriodora, tea tree, and niaouli oils in equal parts. I used one suppository per night just before laying down in bed. At the time I began this first trial I was developing a fever in the evening in addition to my normal midday fever. Within three days of starting the suppositories, the PM fever was gone. By day seven I was feeling significantly less mucus in my lungs and my energy levels improved.
After finishing the 10-day course I waited five days before starting my second course. As expected, the PM fever began to return, my energy levels declined, and my mucus load increased slightly. My second trial included a new mixture of oils that included thyme (ct. thymol), niaouli, rosemary (ct. camphor), Eucalyptus citriodora, and oregano (replacing the tea tree). I did six days of this using a single dose of suppository per night. By day three my PM fever was gone and my energy improved once again. On day seven I decided to double the dose, using two suppositories per night. This improved my lung symptoms even more quickly. I used the double dose of this second batch for three days. I had decided to use 25% coconut oil and 75% cocoa butter as the carrier oil for this batch, which was a mistake because the melting point for coconut oil is so much lower (about 75 degrees Fahrenheit compared to 93 degrees for cocoa butter and 100 degrees for shea butter) that the suppositories began to get too soft as room temperature and were harder to insert. I had to keep them in the freezer to maintain their firmness.
I began the third batch of suppositories the following day. This time we used a mixture of 65% cocoa butter and 35% shea butter for the base oil, which resulted in a perfect consistency when kept in the refrigerator until insertion. We used 10 drops of essential oils per suppository, which included equal parts of rosemary (ct. camphor), lemongrass (Cymbopogon citratus), niaouli, tea tree oil, Eucalyptus citriodora, and oregano. I used this blend for seven days. Again, my mucus was reduced to the point where I no longer heard crackling on my breath when inhaling, not even in the morning. My mucus level throughout the day was so low that even with rigorous exercise (e.g. hiking up a long hill) my lungs remained open without shortness of breath or panting, and I hardly coughed or produced any mucus at all. The AM fever still remained (still controlled by acetaminophen or ibuprofen), however my energy no longer slumped midday.
Comparing essential oil delivery techniques, I believe suppositories to be more effective at combating deeply established infection in the distal airways of the lungs. However, using both delivery systems simultaneously would be beneficial. It seems that for both inhalation and suppositories of essential oils, continuous use is critical for maintaining cessation of my disease symptoms. Given the severity of my infection, essential oil use has so far not been able to eradicate any of my microbial colonizing species, however it has been able to reduce microbial populations to the point where the body is less overwhelmed by the burden of infection, reducing disease symptoms (i.e. mucus production, severity of fever, fatigue, etc.). After three weeks of rectal suppositories, my sputum culture showed a reduction in the MRSA population (from “heavy” to “moderate”), a steady Pseudomonas non-mucoid population at “few”, an elimination of the mucoid Pseudomonas strain, and an emergence of Methicillin-sensitive Staph (MSSA). The emergence of the MSSA seems to me to be a good sign because I assume that the MSSA was in the lungs before but that the biofilms of MRSA and Pseudomonas prevented it from being exposed enough to be coughed out and cultured. It is possible that in a non-CF lung, or in a CF lung with less microbial burden, essential oil use alone, via inhalation and/or suppositories, could be enough to eradicate a microbial infection.
How To Get Started
If there are any aromatherapists in your area, you might work with one to make you up some suppositories. My aromatherapist charges me about $12 for a week's worth of suppositories, depending on what oils we use. You can also buy all of the ingredients and make them yourself. It may be wise to go for a low dose (5 drops per suppository) at first and then working your way up, especially for the spicier oils like thyme, oregano, and cinnamon. A suppository is inserted at night right before going to bed. Usually the first suppository is uncomfortable for about 3 minutes, then the spiciness subsides. By day 3 I usually don't feel it at all, even with something as spicy as cinnamon oil.
If you're considering this as a treatment protocol for your child, try it yourself first. It takes a bit of conscious control to keep the suppository in for the first few minutes - your body detects something in there and the urge to go to the toilet is strong. Make sure to go to the bathroom beforehand! A kid might have to be coached to resist the urge. After a few minutes the urge goes away and it's easy to ignore its presence. The carrier oil (cocoa butter, etc.) is not absorbed via the rectum, just the essential oils, so in the morning you may see oil slicks in the toilet, which is totally normal.
Well, there you go. If anyone is brave enough to try it, let me know what you think! I hope it is as effective for you as it has been for me!
