As we become so dependent on antibiotic pills, the bacteria become even more resistant and even produce and evolve on a larger scale. As these medicines were invented and started to be used in the 1940s (20 century), our ancestors used to use natural antibiotics to fight any fungus, bacteria, or viruses that can be a safe and natural replacement to antibiotic pills and are still used today by some holistic doctors. According to WHO, drug-resistant bacteria is the biggest threat to humanity nowadays.

So, why do not you try some natural elixirs that are gaining popularity these days as the whole world is going green? You probably know some plants have antimicrobial properties and have heard that garlic can replace penicillin? So, let's see which powerful plants and foods can boost your immunity and give that support when you feel sick?

What Is A Natural Antibiotic?

Natural antibiotics are natural substances with antimicrobial properties and can be used as a natural substitute for drugs (usually antibiotic pills). They can easily become part of your everyday diet and you should use them more often to stay safe from all the bacterial infections and reduce the intake of antibiotic pills. Still, it is advisable to consult your doctor if you use them and you try to substitute any prescribed treatment.

Natural Antibiotic Foods


Stubborn bacteria can be treated with garlic as it can defeat some of its key components and can also destroy the biofilm, the protective shield of the bacteria confirms one study from Copenhagen (1). Garlic contains a compound called alliin. When chopped or crushed, it forms another substance called allicin, which is supposed to have powerful antibacterial properties and other health benefits and gives it a strong smell. (2)

The NCCIH states that there isn't sufficient evidence to show whether garlic can treat the common cold. In addition, another research has shown mixed results relating to benefits in lowering cholesterol levels in patients.

Garlic may also help treat these issues:

  • Chronic bronchitis
  • Chronic mucus in your nose and throat
  • Sore throat
  • Sinus problems
  • Recurrent colds and respiratory infections
  • Chronic earaches
  • Flu
  • Yeast infections

It has a strong taste and causes bad ingestion in some people and when taken in large quantities, may cause ulcers or anemia. In addition, it sometimes can interfere with some medications ( saquinavir, a medicine used to treat HIV) and if you use this medicine, you should speak with your doctor before eating garlic.

It is recommended to be eaten raw and it is believed to be a natural penicillin.

Manuka Honey

Honey has been documented as one of the first antimicrobial cures and as a wound healer due to hydrogen peroxide production. (8)

Thus, it can be used against any pain and inflammation. In July 2010,  FASEB Journal explains for the first time how honey kills bacteria.

The bees make a special protein defensin-1, that they add to the honey. Scientists believe that one day it can be used for the treatment of skin infections, and for the development of new drugs that can fight antibiotic-resistant infections. (9)

Manuka honey is made from the nectar of manuka trees (Leptospermum scoparium) found in Australia and New Zealand, and it has an additional component to its potent antimicrobial activity that differs it from other types of honey. It has a higher level of enzymes (referred to as the Unique Manuka Factor (UMF) that makes him unique. (10)

Manuka honey can kill Staphylococcus and Streptococcus bacteria (that cause golden staph infections and strep throat). Still, different Manuka honey has different antibacterial properties and in some of them, antibacterial content is not that high.

One study confirms that Manuka honey can prevent various drug-resistant pathogens effectively, it has a large spectrum of antibacterial capabilities, unlike most antimicrobial agents. Moreover, few studies have shown that Manuka honey can kill bacteria that are living in biofilms. This means Manuka honey can be used to prevent the growth of bacteria in wounds,  implanted devices and mucosal surfaces. (11)

Notes: You should be careful when using honey if you have diabetes as it is high in sugar. It should not be given to children under 1 year of age and be extra careful if you are allergic to pollen.

Echinacea ( purple cone-flower - E. angustifolia, E. purpurea, E. pallida )  is a lovely pink flower that is related to sunflowers, daisies, and ragweed. Its leaf, root, and flower are used in medicine to activate the chemicals in the body that decrease inflammation.

One of the most common uses is to treat the cold and flu and one study confirms that Echinacea kills bacteria, including Streptococcus pyogenes (S. pyogenes). (12)

It might also help with inflammation as it has antibacterial properties.

Echinacea Tea

This tea is a different herbal drink from traditional teas and is usually made from the dried purple flower of E. angustifolia and E. pallida (Echinacea varieties). It is decaffeinated and you do not get the energy that you usually feel after drinking the black tea. You can drink it for a week, several times per day when the first signs of flu or cold appear to cut the duration of the illness.

Oregano Oil

For centuries, oregano (Origanum vulgare) has been used as a spice and flavoring agent in the kitchen. The key components associated with antimicrobial activities in oregano were proved to be carvacrol and thymol. (13)

You can use oregano oil, which is a food supplement as a natural antibiotic, but always diluted in distilled water or another carrier oil ( coconut or olive oil, for example).

It's available in supplement form, soft gel capsule as a pill where the oregano oil is diluted as it is very strong. If you want to dilute it by yourself, the most common recipe is adding 5 to 6 drops for every ounce of carrier oil.

One study confirmed that oregano oil is effective against many bacteria, including Escherichia coli (E. coli). (14)

You are allowed only 1 to 2 drops per day and use the therapeutic grade oil to reap all its benefits. Talk to your doctor if you take any medications for possible interactions with oregano oil. You can take the oregano oil for a period of 2 weeks only.

It has shown great results in killing Pseudomonas aeruginosa, a common bacterium found in chronic wounds. (19)
