If you get an infection, your doctor will most likely prescribe antibiotics to kill or inhibit the growth of the bacteria that is making you sick. Where did antibiotics come from and what did our ancestors use to alleviate their health issues? The answer lies in nature.
Most of the modern antibiotics are derived from natural sources, however, they also contain lots of chemicals that can cause numerous unwanted side effects. While strong and aggressive antibiotics are sometimes necessary, we should consider trying ‘original antibiotics’, the healing plant extracts, essential oils, and foods that have antibiotic properties before we resort to synthetic drugs.
There are a couple of important reasons to opt for natural antibiotics:
- First of all, the so-called natural antibiotics are strong enough to handle most minor infections.
- Natural antibiotics are not only great for treating infections, they are also known for boosting the immune system, while synthetic meds weaken our natural defense system.
- Natural antibiotics have fewer (if any) unwanted side effects.
- Excessive use of synthetic antibiotics makes bacteria resistant to them. As such, we must constantly increase the amount of the drugs we consume and thus intensify the negative side effects.
- In addition to killing the bacteria that is making us ill, synthetic antibiotics also destroy the good microorganisms, which are responsible for gut health and play an important role in maintaining a healthy immune system.
Below, you can find the top 12 most effective and powerful natural antibiotics and learn more about how to use them.
1. Garlic

Garlic is considered one of the most powerful natural antibiotics. Its chemical compounds, such as allicin, are proven to have antimicrobial properties and destroy pathogens, which cause common and rare infections. Garlic is effective in combating colds, bacteria, parasites, and other infectious diseases. You can also apply garlic concentrate directly to a wound.
As its antibiotic properties are strongest when it’s raw, it’s best to chop or crush a couple of garlic cloves and let them sit for ten to fifteen minutes before you eat them. This way, garlic releases the enzymes that are converted into allicin. In order to avoid the smell, you can purchase a garlic concentrate or make your own by soaking a couple of garlic cloves in olive oil.
Garlic is generally safe to ingest. However, make sure not to exceed the recommended daily intake, which is up to two cloves. In case you are currently taking any blood-thinning medication, consult your doctor before using garlic as an antibiotic, as it may amplify the effects of your medication.
2. Honey

Honey, especially raw Manuka honey is one of the oldest antibiotics. It contains hydrogen peroxide and other powerful compounds that can inhibit numerous drug-resistant pathogens and have a broad spectrum of antibacterial capabilities. Honey contains lots of sugar, which can stop the growth of some bacteria, and has a low pH level, which keeps the moisture away from the bacteria, causing them to dehydrate and die.
Honey can be used orally or topically. You can ingest one to two tablespoons of honey a day, preferably in the morning, due to the high sugar dosage. Make sure not to heat it, as heating honey destroys its beneficial properties. You can also apply honey directly to a wound or infected area. In both ways, honey will kill off the bacteria and promote the healing process.
3. Oregano

Oregano is a popular Mediterranean herb and a powerful natural antibiotic. It can be ingested as a spice (used in Italian dishes and salads) or inhaled in the form of essential oil. The healing compounds found in oregano essential oil, such as carvacrol and thymol, boost our bodies’ natural healing abilities when inhaled.
Oregano essential oil can be diffused in the air to clear any infections of the upper airways. It can be used topically, however, not undiluted directly on the skin. Oregano oil has been proven to help reduce inflammation, heal gastric ulcers, improve digestion, treat fungal infections, and accelerate the loss of excess weight. To treat fungal infections on the skin, use it topically, however, make sure to add one drop of it to a teaspoon of carrier oil (e.g. coconut or olive oil).
Small amounts of oregano oil can also be ingested. Orally, it is effective against many types of bacteria, including Pseudomonas aeruginosa and E. coli (Escherichia coli). Make sure to use very small dosages (1-2 drops mixed with water or olive/coconut oil. In this case, ensure to only use 100% therapeutic grade oil and in case you’re taking any medications, make sure to consult your doctor. Oregano oil should not be used for more than 14 consecutive days.
4. Thyme

Thyme is another powerful herb that can be used as a spice or as an essential oil, which is for external use only. Thyme oil has been found especially helpful against antibiotic-resistant bacteria. Dilute the oil with a more neutral carrier oil (e.g. olive or coconut oil) and apply it to the affected area. Undiluted oil should not be applied directly to the skin as it may cause irritation or inflammation.
Note: People with hyperthyroid issues or high blood pressure should not use this essential oil.
5. Turmeric

Turmeric is an amazing spice known for its countless healing properties. It can be used both topically and orally and it’s great at killing a large variety of bacteria.

Numerous studies have shown that small daily dosages of turmeric (used with a dash of black pepper and olive/coconut oil for better absorption) can even help prevent cancer. It can also be used with honey and ginger (for example, in lemonade) and since all three foods are effective antibiotics, the powerful combo will help you fight off any infection in no time.

It has anti-inflammatory properties and can boost the immune system in times of stress, anxiety, and inflammation. A study has shown that taking ten milligrams of Echinacea per one kilogram of body weight daily for 10 consecutive days will strengthen the immune system by boosting the activity of some white blood cells and help shorten the duration of illnesses that are usually treated with antibiotics.
