Pharmaceutical antibiotics are commonly misused for non-bacterial sore throats, chronic ear infections and earaches, and chronic bladder infections. There are natural antibiotics for humans that will help each of these conditions. 

Eliminating Allergenic Foods will Help Most Earaches, Bladder Infections, and Sore Throats

Eliminating common allergenic foods from your diet and your children’s diet will often help relieve the following infection within a couple of days. Allergenic foods include dairy, milk, peanut butter, eggs, wheat, corn, oranges, refined sugar, honey, dried fruit, and fruit juices.

Natural Antibiotics for Chronic Earaches and Chronic Ear Infections

According to the Encyclopedia of Natural Medicine, two-thirds of children get ear infections by the time they are two years old. Usually, ear infections are caused by food allergies and do not require antibiotics.


You may want to turn to the antibacterial herb Echinacea, to help relieve the pain of an earache. Children under the age of 6 can take half the size of an adult dosage. An adult dosage of Echinacea is ½-1 g of dried root in a cup of tea or 325-650 mg in an Echinacea supplement. Do not take this if you have an autoimmune disease or are allergic to ragweed. 

Oregon Graperoot 

Oregon Graperoot is one of the best natural antibiotics because it has Berberine, a powerful antibacterial ingredient. Others like it are goldenseal, barberry, and gold thread, which make great alternative to Oregon Graperoot. The dosage for Oregon Graperoot is 1 teaspoon of tincture in water three times per day or if you prefer a supplement take six 500-600 mg capsules per day. Avoid this herb if you are pregnant.


Garlic helps fight off bacterial infections and viruses like the cold and flu. Eat one or more fresh cloves per day or if you want a quick and easy solution take three 500-600 mg per day.

Lemon Balm 

Lemon Balm tastes just like lemon and is antibacterial and antiviral which will help an earache. It’s leaf makes  pleasant tasting tea, and it’s advised to drink 3 to 4 cups per day. Alternatively, you may choose to take nine 300-400 mg capsules per day.

Natural Antibiotics for Non-bacterial Sore Throats

Strep throat and rheumatic fever are appropriately treated with penicillin or other antibiotics. Rheumatic fever occurs three weeks after strep throat and is uncommon thanks to pharmaceutical antibiotics. It takes the doctor just a few minutes to test for strep throat, whereas it used to take two days, which caused an over-prescription of antibiotics. Fortunately, we do not have that problem today, and the over-prescription of antibiotics for strep throat has significantly reduced. 

However, 90% of sore throats are not associated with strep and instead have to do with our diet. By eliminating the allergenic foods mentioned earlier, you can usually help your throat feel much better and rather quickly with the use of natural therapies.


Herbal remedies might include drinking ½ to 1 g of Echinacea in a cup of tea three times per day or taking 325-650 mg of an Echinacea supplement three times per day.

Vitamin C, Vitamin A, Beta-carotene, Zinc

Other supplements you may want to take are 500 mg of Vitamin C, 1,000 mg of Bioflavonoids, 5,000 IU per day of Vitamin A (not if you’re pregnant), 25,000 IU per day of Beta-carotene and 20-30 mg per day of Zinc.

In addition to taking the supplements above, you will also want to decrease your diet to less than 1,000 calories and increase your water intake to 8 oz every hour. That will have the biggest impact on soothing the pain of your sore throat. Also, be sure to get plenty of sleep and rest.

Natural Antibiotics for Chronic Bladder Infections

According to the Encyclopedia of Natural Medicine, bladder infections, also called urinary tract infections or cystitis happens most often in women. Ten to twenty percent of women experience some kind of bladder discomfort once per year. The bacteria E. coli is the cause of ninety percent of bladder infections.

Cranberry Juice & Diet

The most popular preventative treatment is cranberry juice; however, commercially available juices are mixed with sugar and water, which is only going to make matters worse. Fresh cranberry juice is recommended, mixed with fresh blueberry or fresh pineapple juice to sweeten it. 

If the bladder is irritated, and it is caused by an infection called Chronic Interstitial Cystitis, it is treated in two ways; diet and supplements. First is cleaning up the diet to help support the immune system. Part of cleaning up the diet includes getting rid of allergenic foods as mentioned above and drinking 64 ounces of water per day, and fresh cranberry juice. If you mix cranberry juice and blueberry juice, these together will help rebuild the lining of your urinary wall and prevent bacteria from sticking to it and causing an infection.  Herbal remedies and supplements are also used to help enhance the integrity of the bladder tissue and the actual lining wall of the bladder. 

Uva Ursi

It’s possible Uva Ursi is a more effective prevention for urinary tract infections than fresh cranberry juice. A study was conducted on fifty-seven women over a period of one year. It was a double-blind study, so half of the women received a placebo. The conclusion of this study was very obvious that the women who received treatment had no symptoms during the year while taking uva ursi versus the women who were not. Uva ursi for the win! 

You must be careful taking uva ursi because if you take too much, it may cause you to get nauseous, ringing ears, shortness of breath of a feeling of suffocation. Let’s avoid all of that by NOT taking 15 grams (1/2 ounce) of dried leaves, that’s where the side effects begin to show up. 

Citrate, Vitamin C, Bioflavonoids, and Vitamin A

You may also take 125-250 mg of a Citrate supplement three to four times a day, 500 mg every two hours of vitamin C, 1,000 mg per day of Bioflavonoids, and 50,000 IU of Vitamin A per day for one week (if you are not pregnant).

Natural Antibiotics for Tooth Infection

Good to Know: What Are Herbal Constituents?
