What is the best home remedy for treating sinusitis?

Snort warm salt water. . boil a jug, poor into a bowl and mix vicks, put a towl over your head and do ten inhalations. It will clear your sinuses and unblock them

Make a weak salt solution with warm water. Put solution into a small tea pot with a spout. Tilt your head to the left side, put the spout into the exposed right nostril and let the water run into that nostril. WAIT. The solution dribbles through your sinusis and then exits through the left nostril where gravity helps it leak out. Tilt head to the other side and repeat. Do this every morning to clean out your sinusis. This is an ayurvedic remedy.

Saline irrigation is sometimes effective for sinus problems, but if it is actually sinusitis, the only real "remedy" is antibiotics. If left untreated it can become more serious, and even cause pneumonia.

Start with drinking a lot of healthy liquids-water, juices, etc.
Take hot showers, without the exhaust fan on in the bathroom.
Also, while you are in the shower, close your eyes, mouth, and gently place your face (while holding your breath for a short time like a few seconds) with your nose (top of it) under the shower water. You can repeat this for a few seconds at a time several times. Or, if you don't want to do it that way, you can splash water onto the top of your nose a few times.
Or, if you don't want to shower, or in between showers, use a wash cloth with as hot (really warm) water as you can stand, wring it out to being damp, and place that on top of your nose for a few minutes a few times per day.
Also, try blowing your nose to clear the mucous out of your nostrils several times per day too.
If you want to, talk with your local pharmacist aobut over the counter products like Vicks Vaporub, etc. to help.
Also, if it doesn't get better soon, being sinusitis, (a sinus infection?) you may need to go to the doctor and get a prescription for antibiotics for a week or so.
Take care.

A combination treatment which I have found to be effective is using saline nasal irrigation to clean out the nasal passages followed by treating the nasal passages with 3% hydrogen peroxide and oil of oregano.
By inserting a cotton swab in the nasal passage after dipping the cotton swab in the hydrogen peroxide. Do this in each nasal 4 or 5 times about 30 minutes after the nasal irrigation. Make sure the cotton swab is saturated with fresh 3% hydrogen peroxide each time.
The nasal cleansing removes all gunk in the nasal passage. The hydrogen peroxide is partially absorbed and kills the bacteria and virus in the nasal passages.
I have also found that a very dilute solution of oil of oregano on a cotton swab is helpful in getting rid of any fungal infection which is usually the cause of the nasal infecton in the first place. Be aware that the oil of oregano will burn.
