Research Data:

A recent Mayo clinic study linked mold and fungi in the nasal cavities with chronic sinusitis. Agrumax was given to patients in another clinical study authored by Donald P. Dennis, M.D., F.A.C.S, as part of his sinus protocol. A special, compounded prescription-strength Agrumax spray was used four times per day. The nose was irrigated with an electric nasal irrigator using normal saline (0.9% salt water in distilled water). Patients showed marked improvement when they limited their exposure to mold by treating fungi (nasally and in their environment), according to the study protocol, including the use of Agrumax.

Pair this with Breathe-Ease XL...excellent nasal wash...i use 2-3 drops Agrumax,1 cup distilled water and 1/2 tsp Breathe-Ease XL for daily cleanse. If congested...I increase Breathe-ease XL to 1 tsp to 8oz. water for hypersaline solution. Very effective.
I have chronic sinus infections, candida and asthma. Since using Agrumax, I have been breathing much easier. If you have Candida yeast, use sparingly at first. I added 4-5 drops instead of 2 the first time. It was so effective I almost choked on the large amount of yeast it cleared. I'll be an Agrumax user forever and breathe easier for it! Try it - you cannot lose! (I combine with saline/baking soda solution daily.)
I just started using this product 2 months ago. I have noticed less postnasal drip than I usually have. It has helped me a lot during this past spring allergy season. I am going to keep using it.
Allergy symptoms off the chart this year. I mix every OTC allergy med to get relief and have an inhaler 2 times/day plus a rescue inhaler as needed. Looking for anything to help. Started taking this "10-12 drops" twice/ day and within 2 days I cut down to 1 Zyrtec D per day. Been taking for 3 full weeks now and cut down to 2-3 times per week needing allergy relief. Unsure if coincidental to bulk of pollen season being past, but was completely miserable prior to this.
I have been using this product for over a year for sinus problems. I add 3-5 drops to 8 ounces of salt water in my neti pot, rinsing twice a day. I have found that I can breathe so much better when using this in addition to the salt water. I have not had any sinus infections in over a year since using Agrumax. I would highly recommend this product to anyone that suffers from sinus problems.
I get sinus infections at the drop of a pin. Using this product to irrigate my sinus passageways gives me almost instant relief and after a few uses they are cleared up entirely.
Prior to starting a daily dose of Agrumax I suffered from frequent colds and sinus infections every year. Then 1 year ago this month a friend gave me my first bottle and I started taking 12 drops every morning. Now my sinus problems are a thing of the past.
Daily use with breathe ease XL has kept my sinuses virtually clear...also no colds since starting using these products 1 year ago....try it
I've used Agrisept/Agrumax for 12 years. I put it in saline spray and mist twice a day and I put a few drops in water or juice before meals. It has reduced sinus allergies tremendously and irritable bowl syndrome. My friend's baby stopped needing tubes in his ears when she sprayed his nose. It is also excellent for Crohn's disease. Citrus bioflavonoids are proven to regulate immune Tcell activity.
Chronic Sinunitis has left me tasteless for nearly three years. Since using this product, I have gained my taste and smell back! Agrumax is definitely a product I recommend for sinus issues.
