Natural Antibiotics

Natural antibiotics fight off infections and fast! In certain circumstances, a natural antibiotic is the best way to heal your small infection. The traditional form of antibiotics are very effective, but eventually, we will reach complete immunity to these pills, and the conventional antibiotic will no longer work on deadly infectious diseases. A lot of these infectious diseases that are currently under control will run rampant once again through our streets, and we will have no remedy for it. Let’s be thankful we haven’t reached this point yet. 

It is essential to understand that western antibiotics have been saving lives for several decades. Our quality of life has significantly improved because of the antibiotic pills, and we are thankful for this. The expected survival age has increased dramatically since the advent of antibiotic medicines. 

They are, however, over prescribed in hospitals today because people believe these pills are the answer to almost all their health concerns when in actuality, a natural antibiotic may solve their problems and help alleviate their symptoms just as quickly.  

What is a Natural Antibiotic? 

A natural antibiotic is an herb or plant food that contains the constituents of antibacterial or antimicrobial. The definition of antibiotics is a chemical that kills or slows the growth of bacteria. Therefore an antibacterial or antimicrobial herb/plant fits that description. 

A List of the Best Natural Antibiotics

Below is an all-inclusive list of the best natural antibiotics in the form of herbs. Each has an antimicrobial or antibacterial constituent or ingredient and will help kill bacteria or keep it from multiplying.

IMPORTANT: Please do not self-diagnose ever! It is unsafe and impossible to do so. You must seek help from a licensed Naturopathic practitioner before taking any of the herbs for medical purposes. 

The Top 5 Best Herbal Natural Antibiotics

These are the 5 best natural antibiotics because they contain a special constituent called Berberine. Berberine is a powerful antibacterial ingredient. It destroys bacteria, yeast, and protozoa. Giardia, Cholera, Amebiasis, and visceral and cutaneous Leishmaniasis are medical treatments often treated with berberine containing herbs such as the following.  

Goldenseal (Hydrastis canadensis)

Goldenseal root is used as a laxative in small doses. It treats colds, sore throats, the flu, acute and chronic ear infections, conjunctivitis, and vaginitis. It’s an endangered plant, and we recommend only using the organic plant. It is essential not to use the fresh plant as it is too strong and may cause harm to your intestines. Do not use it if you are pregnant, hypoglycemic, or experience shakiness and hypotension because it may exacerbate these conditions. 

Goldthread (Coptis chinesis)

Goldthread is used similarly to goldenseal because it treats uterine infections. It also helps with influenza, reoccurring colds, bronchitis, tonsillitis, sinusitis, and allergies. You must speak with a naturopathic doctor before using this! You might be susceptible to a heart or kidney failure if you don’t, so watch out! 

Barberry (Berberis vulgaris) or Oregon grape (Mahonia repens) 

The bark of the stem and root are used from the Barberry or Oregon grape plant. It treats intestinal issues and infections that involve the urinary tract, the raspatory tract, and the gastrointestinal tract. If you are pregnant, don’t take this.   

Yerba mansa (Anemopsis californica)

Yerba mansa is used for sore throats, ear infections, skin ulcers, colds, or the flu, and more. It’s going to have an astringent, aromatic, and slightly acrid taste to it. 

Another 17 of the Best Natural Antibiotics 

Calendula (Calendula officinalis)

Calendula is a beautiful flower that grows like a weed. It’s the kind of weed you want to grow in your yard because when in bloom it’s an attractive yellow flower. The flower part is used for medicinal purposes, and it helps heal wounds, bruises, burns, boils, and rashes. It is also beneficial to infectious disease, which is why it made it on this list. It has anti-inflammatory and antiseptic properties, among others. Do not take this one when you are pregnant either because it is an emmenagogue (increases menstrual flow) and an abortifacient. Studies proving it’s efficacy in the treatment of the conditions mentioned previously include: (Tommasi et al., Structure and in vitro Antiviral Activity of Calendula officinalis Extracts. Plant Medica. 1990;56-658) (Lawrence Review, Calendula, August 1992.) (De Tommasi N, et al. Structure and in vitro antiviral activit of the sesquiterpene glycosides from Calendula arvensis. Journal Nat Prod. 1990;53:4:830.) 

Cinnamon (Cinnamomum spp.)

Cinnamon made our list of the best natural antibiotics because it is used for helping your body get rid of its waste trapped in your intestinal system. It’s not a laxative, but it helps ease digestion. When you use it too much, it can cause your intestines to bleed, so be careful. Cinnamon is also used to treat dysmenorrhea (which means menstrual cramps) because it stimulates the uterine wall and causes it to contract. Did you know that large doses of cinnamon, so more than 2 grams may cause hallucinations and death? Do not take this one when you are pregnant either because it is an emmenagogue and an abortifacient as well.

Clove (Syzygium aromaticum)

Couch Grass

Echinacea (Echinacea spp.) 

Usually, the root is used, but sometimes your body might fancy the seeds or flower. The root will tingle your tongue when you eat it. Everyone knows this herb for its effects on a cold, however, you must drink the tea three days before cold symptoms occur for it to work, so it’s really not all that helpful on a one-day notice when you do start feeling crummy. If you do experience frequent respiratory infections, this might be an herb you will want to drink in your tea on a regular basis. What it really does is it’s antibacterial properties help fight off infections and heal wounds. It’s actions are antiviral, antibacterial, anti-inflammatory, antifungal, and many other wonderful things. Its best use is for bacterial infections and viral diseases, allergies, swollen glands, and gum disease, but certainly not it’s only use. 

Elecampane (Inula helenium) 

The taste of elecampane is sweet, and it’s a beautiful subtle flower is tall, but the medicinal benefits lie within her roots. Elecampane is antiseptic, expectorant, a bitter tonic, carminative, antiparasitic, anti-inflammatory, a diuretic and so much more. It’s great for intestinal parasites and nasty intestinal worms without causing side effects. No side effects are a miracle unheard of with any pharmaceutical! You have to take it with a laxative too, so be sure to call a Naturopathic physician for guidance on how to properly get rid of your worms if you’re trying to.       

Eucalyptus (Eucalyptus spp.) 

Garlic – fresh (Allium sativa)

The clove of garlic benefits parasitic and bacterial gastrointestinal infections. Kids with pinworms will benefit from a garlic enema and allicin an active ingredient in garlic is slightly helpful for stomach ulcers. It’s antibacterial, antifungal, antiparasitic, diuretic, carminative, anticoagulant, and a lot of other things. It has a lot of contraindications, and it is an excellent idea to talk to your doctor before taking this plant for medicinal purposes. Our rule of thumb with herbs, if it doesn’t taste good, don’t consume it, your body is telling you, you don’t need it. 


Horseradish (Armoracia rusticana) 

Lomatium (Lomatium dissectrum) 

Lomatium is in the parsley family, and the root contains all of its healing properties. The constituents are antifungal, antibacterial, antiviral, and immunomodulator, which helps with colds, flues, bacterial and viral infections, as well as urinary and respiratory tract infections.

Myrrh (Comminphora myrrha)

If you have sore gums or a soar mouth you can gargle Myrrh, know that it’s sticky and will stay on your teeth, which is probably why it’s so good at healing it. You can also use it topically to help your wounds. 

Old man’s beard (Usnea spp.)

Oregano (Origanum vulgare)

Oregano is a common kitchen herb that is antimicrobial. You can drink it as a tea or use it in a tincture to help your digestion, flu, colds, asthma, or bronchitis. Don’t put the essential on your skin though because it might irritate it.

Yarrow (Achillea millefolium)

Yarrow is used for all kinds of women’s reproductive issues, excessive bleeding, for example. It’s a diuretic so it will dehydrate you.  

Ways to Take Natural Antibiotics

There are two ways to get natural antibiotics, internally or externally. You can ingest these in the form of food, herbal tea, or supplement, for example. You can apply these to your skin in the form of an herbal salve or balm. 

Herbal natural antibiotics may be used in a poultice, a tincture, a cup of tea, a healing balm or salve, can be found in essential oils, or used to spice up and add flavor to your food.

If you have a small scrape or open wound, you will want to use an external application in the form of a healing salve or balm. You can make your own homemade salve, or you can purchase one from a trusted online source or at your local apothecary. 

If you choose to make these herbal remedies at home here is some instruction on how to do so:


This is the easiest way to get your natural antibiotics. All you have to do is take a pill, something everyone is familiar with. You have to be careful which supplements you purchase because some brands will stuff their products with fake ingredients. 

A Poultice

Mash all the healing herbs you want to use together and then add flour. Mix it together until it’s a clay-like consistency. Apply it to a cloth and then lay it on top of your wound or rash. 


Cook an herb or several in alcohol or glycerin and then store it in a jar with a dropper. Use the dropper to put several drops under your tongue depending on the dosage you need for that herbal remedy. The glycerin is sweet and should help make a bitter herb palatable. 

A Cup of Tea

You can purchase empty tea bags and make your own blends, or you can put herbs directly into a French press or a pour-over with a paperless filter. This will allow the herbs to sit in the water for as long as you need to steep your tea and easily remove the herbs after your tea is ready and keep the herbs from getting into the water.

A Healing Salve or Balm

You can find thousands of recipes online. It’s basically a combination of vegetable oils and essential oils, melted together. When the oils are melted together and cooled a bit, you then add essential oils, and voila, you have a salve or healing balm. You may infuse your herbs in the oil before making your balm. This will infuse the healing properties into the oils and make your balm extra strong. For a bacteria-free oil, you may boil the herbs into the oils instead of letting the oils soak for two weeks or so.

Essential Oils

Some essential oils are safe to apply directly to your skin. Some need a carrier oil or need to be diluted with water.

Food Spice and Flavor

Fresh herbs are rich in flavor and add the most decadent smells and taste to our food. If you like Indian food, you know exactly what we are talking about. There is no other country that we know of, that spices their food like they do in India.

Natural Antibiotics for Tooth Infection

A natural antibiotic for toothache is clove oil. Apply clove oils temporarily in small amounts to your tooth. Kava kava is another great natural antibiotic for toothache. You may also apply echinacea or prickly ash topically on the painful area in your mouth to help alleviate some of the pain.

Good to Know: What Are Herbal Constituents? 

It’s important to understand what constituents are and why they are so crucial to the healing arts. You’ve heard many of them before and are probably super familiar with the constituent’s antibacterial, antioxidant, anti-inflammatory, antihistamine, toxic and several others. The definition of a constituent is the physiological action an herb may take on the body. For example, antimicrobial means it kills bacteria. There are twelve main groups of herbal constituents, and those are Alkaloids, Anthocyanins, Anthraquinones, Cardiac Glycosides, Coumarins, Cyanogenic Glycosides, Flavonoids, Glucosilinates, Phenols, Saponins, and Tannins.
