The A-Z of 228 natural antimicrobial and healing plants

Plants have evolved to produce their own powerful antibiotic, antifungal and antiviral chemicals to fight off bacteria, fungi and virus infections and, when consumed, these chemicals can have the same effect within the human body. In the 15th century, the spice traders and merchants were the 'pharmacists' of the day as they knew about the powerful properties of the herbs and spices they traded from India and throughout Europe. Thieves oil was a concoction they invented that had powerful antimicrobial properties that protected them from the bubonic plague. Read more

It is especially useful in combating the hepatitis and herpes viruses. Oleuropein is the compound in olive leaves that are responsible for the anti-bacterial, antifungal and antiviral activities and can effectively combat many microbial pathogens including Candida krusei, Herpes and Salmonella typhi. Olive twigs have been chewed in the past to protect teeth and gums against oral bacteria.

Oregano (Origanum compactum)

Oregano contains powerful antimicrobial agents that work against many infectious organisms including the Escherichia coliand Helicobacter pylori bacteria, the Dientamoeba fragilis trophozoites and Toxoplasmosis gondii parasites and viruses such as the Norovirus and others that cause colds and influenza.

Oregon grape root (Berberis aquifolium)


Oregon grape root is a rich source of berberine which is a compound that is highly effective against fungi, protozoa, worms and parasites as well as bacteria and viruses. Berberine is an isoquinoline alkaloid present in the roots, rhizome and stem bark of this herb.


NOTE: There may be an interaction between berberine and many prescription medications, including metformin, and it should not be used by pregnant or breastfeeding women due to potential for adverse effects for the foetus. Excess berberine can cause brain, kidney and liver problems and should never be taken as a supplement on its own. It has been shown to cause liver tumours in rats and people with heart problems can be induced by berberine to have arrhythmia attacks.


Papaya (Carica papaya)


Papaya, also known as paw paw, has the enzyme papain in its peel, caricin in its seeds and the alkaloid carpaine in its leaves which are all potent antibiotics and capable of killing parasites. Papain also lowers inflammation, enhances the immune system, aids with faster repair from injuries and has pain relieving properties. After treatment with antibiotics eating papaya, or drinking its juice replenishes the good intestinal bacteria, which was destroyed by the antibiotic treatment. Home applications of papaya leaf and bark extracts can be used to deal with sore gums and toothaches and papaya peel can be used for skin wounds that do not heal quickly as it encourages renewal of muscle tissue.

Paprika (Capsicum annum)

The anti-inflammatory properties of paprika makes it a good analgesic to use topically for skin disorders. It does contain the antibiotic component capsaicin but not as much as is found in the chilli pepper. However, it is useful for those that find chilli pepper unpalatable.

NOTE: Paprika is not suitable to be used medicinally by pregnant women.

Parsley (Petroselinum crispum)

In studies, extracts taken from parsley stems have been shown to produce potent activities against the Bacillus subtilis and Escherichia coli due to their phenolic content. Parsley is a good choice to prevent and treat infections of the eyes, genitals, intestines, urethra and urinary system. Parsley can also be used externally, as a tea, on abscesses, eczema, itching, rashes, toothache and wounds and kills head lice and oral bacteria.

NOTE: Parsley is one of the most potent foods of the common vegetable kingdom and, as a juice if properly and completely extracted, it is wise not to drink more than four ounces daily without the addition of other vegetable juices because otherwise it is likely to create a serious disturbance of the nervous system.

Passion flower (Passiflora incarnata)

Passicol, an alkaloid found in passionflower, kills a range of bacteria and fungi and it also contains other antimicrobial components such as flavonoids and glycosides. In studies, the stem tissues of the passionflower showed high levels of inhibition against the following:

Bacteria: Staphylococcus aureus and Torulopsis glabrate.

Moulds: Arthroderma flavescens, Aspergillus fumigatus, Epidermophyton floccosum, Microsporum canis, Microsporum gypseum, Microsporum cookie and Penicillium notatum.

Yeasts: Candida albicans, Candida krusei, Cryptoccoccus neoformans and Rhodotorula.

Ethyl acetate extracts of the passionflower stems also showed potent activity against all these as well as the mould Trichophyton quinckeanum and the bacteria Clostridium sporogenes, Escherichia coli, Salmonella enterica serovar Stanley and Shigella sonnei. This involves shade drying the stems at room temperature in a clean environment to avoid contamination for 14 days and then grinding them into a powder. Extract of this plant can be made by the maceration method using ethyl acetate as a solvent for 72 hours at room temperature.

Passion fruit (Passiflora edulis)

Passionfruit can help with the recovery of liver and kidney disorders as well as trigger immune enhancement and increase the strength of antibodies in the blood.

Patchouli (Pogostemon cablin, Herba pogostemonis)

Patchouli has very powerful antibacterial properties and can promote the secretion of gastric juices, enhance the digestion, relieve gastrointestinal spasms, dilate the capillaries and induce perspiration. It is sometimes used with galangal root to treat malaria and patchouli leaf and tangerine peel can be used to treat the profuse watery diarrhoea and vomiting caused by cholera.

Pau d'arco (Tabebuia serratifolia, Tabebuia impetiginos)

Pau d’arco can successfully treated yeast infections such as Candida albicans and bacterial infections such as Brucella, Staphylococcus aureus, Streptococcus and Helicobacter pylori (common cause of stomach ulcers) and others that can cause dysentery, pneumonia and tuberculosis. The bark contains the active antimicrobial principles, mainly lapachol, quercetin and other flavonoids.

Peelu (Salvadora persica arak)

Peelu twigs have powerful antibiotic properties and have been used as a ‘toothbrush’ since the middle of the first millennia to protect teeth and gums against oral bacteria. The bark is stripped back and the fibres chewed to prevent cavities and gum disease.

Peppercorns (Piper nigrum)


Peppercorns contain agents that can fight against fungi and bacteria especially Enterococcus faecalis, Escherichia coli, Lactobacillus and Micrococcus luteus. Ground pepper is ideal to add to foods that may be infected with any of these bacteria as it will destroy them before they can do any harm in the intestines. Because of its effective antibacterial properties, pepper is often used to preserve food.

Peppermint (Mentha piperita)

The oil of the peppermint has been studied by scientists and shown potent activity against Escherichia coli, Helicobacter pylori, Salmonella enteritidis, methicillin-resistant Staphylococcus aureus (MRSA) and methicillin sensitive Staphylococccus aureus (MSSA). Japanese peppermint (Mentha arvensis) showed the same abilities. It can be taken as a tea three times a day or the vapours inhaled to relieve sinus infections associated with the cold and influenza viruses.

 NOTE: Avoid peppermint oil if pregnant or suffering from gastric reflux or active stomach ulcers and do not apply peppermint oil to the face, especially under the nose of a child or infant.

Pepperwort (Lepidium meyenii)

The glucosinolates found in the root of the pepperwort help to combat serious invasive infection. They are the substances that are also found in other members of the Brassicaceae family (including broccoli, cabbage, cauliflower and other cruciferous vegetables) and are said to be particularly effective in building the body's defences against serious malignant illnesses.

Because pepperwort is so rich in essential fatty acids, minerals, protein and vitamins it is known to aid in repairs of the body’s tissues and bones and is particularly effective in helping with faster recovery from sports injuries.

Perilla (Perilla frutescens)

Being a member of the mint family, the leaves of the perilla have potent antibiotic properties that can act as an antidote to food poisoning from food-borne bacteria and this is partly due to the presence of rosmarinic acid. It has also shown, in studies, the ability to protect against mesangioproliferative glomerulonephritis that can be caused by an infection of the Streptococcus bacteria.

NOTE: Perilla leaves are poisonous to cattle.

Phyllanthus amarus (Phyllanthus niruri)

 Phyllanthus amarus is very effective in treating viral infections of the liver, specifically hepatitis B, and is useful in the treatment of kidney stones and gallbladder stones (active stones and as a preventative), colds, flu, tuberculosis and other viral and bacterial infections such as cystitis, prostatitis, venereal diseases and urinary tract infections. It has also been proven effective in other liver diseases like jaundice and liver cancer.

Pineapple (Ananas comosus)

Fresh pineapple is rich in bromelain, a group of sulphur-containing proteolytic enzymes which digest protein breaking it down into amino acids, its basic building blocks, thus aiding digestion and can also reduce inflammation and swelling.

Bromelain is also anti-parasitic meaning it can kill various parasites and worms in the intestines when drunk on its own during a three day fast. It is also useful for oral health as it can remove stains and plaque build-up on the teeth and help to treat gum infections. The protease in pineapples is useful in the body as it also helps to fight bacterial infections and parasites. Pineapples are rich in iodine which can help to improve thyroid function and some autoimmune disorders.

Pineapples are also rich in many nutrients required for recovery and fast repair of bones and cartilage and can help to rehydrate the body after fever or diarrhoea caused by infections.

NOTE: To maximise the antibiotic and anti-inflammatory effects, pineapple should be eaten alone between meals or its enzymes will be used up digesting food instead.

Pine needles (Pinus aphremphous, Pinus koraiensis, Pinus sabiniana, Pinus sibirica, Pinus sylvestris, Pinus taeda)

Pine needles contain powerful components that can kill the bacteria and viruses that cause colds, respiratory, sinus and urinary infections and helps the body to expel phlegm and mucous.

Poke root contains glycoproteins, resins, tannins, triterpene saponins, many other components and an active glycoprotein lectin called pokeweed mitogen which stimulates lymphocytes.

NOTE: The whole of the plant is toxic and increases in toxicity through the year with children at risk of its very poisonous purple-red ripe fruit. The juice of poke root can be absorbed through the skin and therefore contact of plant parts with bare skin should be avoided. Care must be taken to prepare it properly when using this herb medicinally.

Pomegranates (Punica granatum)

The ellagitannins in pomegranates have a beneficial impact on human gut flora, inhibiting the growth of pathogenic Clostridia and Staphylococcus aureus. The predominant antioxidant polyphenols found in pomegranates are punicalagins which protect the endothelium, a tissue that covers the internal areas of blood vessels and therefore this fruit is useful to consume when recovering from injury or surgery and it is low in potassium so is also a good choice when renal disorders are present. It also helps to alkalise the blood which is useful for preventing infections by organisms that thrive in an acidic environment.


Prickly ash (Zanthoxylum clava-herculis, Zanthoxylum americanum)

The flowers have been found to have antibacterial properties against the pathogenic bacteria that can infect humans such as Bacillus subtilis, Escherichia coli, Klebsiella pneumonia and Sarcina lutea without the side effects of conventional antibiotics.


Wasabi (Wasabia japonica)


Wasabi is a paste made from the ground-up root of this cruciferous Japanese brassica vegetable that can kill harmful food-borne bacteria, reduce blood pressure, kill cancer cells, improve bone strength and liver function, detoxify the body of free radicals and improve gut actions. It is naturally antibacterial, antifungal and antiviral and stimulates the body’s natural immune system.

Its anti-inflammatory and painkilling properties are known to relieve chronic lower back pain, headaches, influenza, joint pain, menstrual cramps, osteoarthritis and tendon pain.  Salicylic acid, found in white willow bark, is a monohydroxybenzoic acid which is a type of phenolic acid that has antibiotic properties.

Wild cherry bark (Prunus serotine)

Wild cherry bark is a very useful expectorant for treating bronchitis, coughs and congestion of the chest as well as digestive disorders and diarrhoea.

NOTE: The bark, leaves and fruit of the wild cherry tree contain a chemical similar to cyanide (hydrocyanic acid) that in large doses can cause serious poisoning and even death and therefore administration should only be done under the supervision of a professional herbalist.


Wild rice (Zizania)


Wild rice is known to encourage the production of white blood cells. It also contains important components such as bioflavonoids like anthocyanins. The high levels of mineral, protein and vitamins, found in wild rice, help in producing collagen which is needed to repair cells of the organs, tissues and blood vessels so is a useful addition to the diet when recovering from injury, surgery or infections.

Wisteria (Bolusanthus speciosus)

In studies, wisteria tree bark and stems have shown potent antimicrobial properties against Bacillus subtilis, Escherichia coli, Klebsiella pneumoniae, Neisseria gonorrhoeae and Staphylococcus aureus bacteria and the Candida albicans fungi due to its phenolic compounds.

Witch hazel (Hamamelis virginiana

The anti-inflammatory and antibacterial, antifungal, anti-inflammatory, antiseptic, antiviral and astringent properties of witch hazel oil make it an idea remedy to help heal and relieve the pain and inflammation caused by infections of the skin or scalp. It can also be used as a gargle for throat infections and as a mouthwash for gum disease. As an ointment, it should be diluted in equal portions of water, arnica oil or extra virgin olive oil and applied 2-3 times daily but should not be used on serious open wounds.

 Wood betony (Stachys spp.)

There are many species of wood betony. Extracts of eight different Stachys species have been found to have antibacterial and antifungal properties, including Stachys alopecuros Bentham, Stachys scardica (Griseb.) Hayek, Stachys cretica ssp. cretica, Stachys germanica ssp. heldreichii (Boiss.) Hayek, Stachys recta, Stachys spinulosa, Stachys euboica Rech., and Stachys menthifolia. Wood betony works well for both children and adults. It is said to help migraine headaches and a poultice or compress made with wood betony can treat skin ulcers, cuts, insect bites and sores.

NOTE: The medicinal species of wood betony should not be confused with Canada lousewort (Pedicularis canadensis) which is also called wood betony.

Yarrow (Achillea millefolium)

Yarrow has been known to have powerful healing properties since the time of the legendary Greek Achilles and therefore it is also known as soldier’s woundwort.  Yarrow flower tops and leaves are the parts of the plant used for medicinal purposes. It can be taken as an infusion (yarrow tea) or as a tincture. Yarrow essential oil, extracted from the plant, is also used. It is antibiotic, diuretic, anti-inflammatory, antiseptic, antispasmodic and astringent due to the presence of resins.

NOTE: Yarrow should not be used during pregnancy as it may stimulate the uterus or if breastfeeding or scheduled to undergo surgery. Yarrow may also cause drowsiness and increase urination and affect blood pressure.

Yellow dock (Gentiana lutea)

Also known as gentian, yellow dock has powerful antimicrobial properties. The root of this herb is especially effective against the methicillin resistant Staphylococcus aureus bacteria (MRSA) and also has antifungal, anti-parasitic and antiviral properties.

 NOTE: The highly toxic white hellebore (Veratrum album) can be misidentified as yellow dock and has caused accidental poisoning when used in homemade preparations.

Yerba santa (Eriodictyon californicum)

Yerba santa helps the body expel mucus from the respiratory tract and is a blood purifier and strengthens the digestive and immune systems due to its potent flavonoid known as eriodictyol. A tea, tincture or syrup is typically made from the leaves, sometimes including the flowers.

Ylang ylang (Cananga odorata)

Ylang ylang contains powerful anti-inflammatory and antimicrobial properties that can help to avoid both sepsis and tetanus by inhibiting microbial growth and disinfecting wounds and protecting the body from infections from bacteria, virus and fungus. It also helps to speed up the healing process of wounds. It can also be used to cure infections of the colon, intestines and urinary tract.

NOTE: Some cases of sensitivity, nausea and headache have been observed when taken in excessive amounts. Otherwise, when taken in recommended doses, it is non-toxic and is not reported to cause any irritation, however, it should not be taken by pregnant or breast-feeding women.

Yoghurt (plain, organic and containing live bacteria cultures)

Yoghurt fortifies the immune system and enhances the immune response system and has powerful antifungal properties for use both internally and externally. It is especially useful for treating thrush infections of the vagina.  It can also relieve stomach upsets especially when caused by antibiotics, due to its ability to replace the beneficial bacteria in the gut. It should be consumed 30 minutes before a meal in order for some of the beneficial bacteria to get past the strong stomach acids.

NOTE: Yogurt is required to undergo a fermentation process with both Lactobacillus bulgaricus and Streptococcus thermophiles, the most commonly used bacteria found in food products. Once the yogurt has fermented, however, there is no regulation stating these cultures must stay in the yogurt. Some companies use heat to remove the cultures after the yogurt has fermented. These yogurts will not include the 'active cultures' or 'live cultures' label on the yogurt. Yogurt containing an 'active cultures' label clearly on the packaging is the best choice.

Zhi mu (Anemarrhena asphodeloides)

Zhi mu is a small ornamental plant that has been used in Chinese medicine and its first recorded use was in 200 BC. It has powerful antibacterial action inhibiting the growth of Bacillus dysenteriae, Bacillus. paraatyphi, Bacillus typhi, Proteus and Pseudomonas and Salmonella typhosa. It can effectively treat infections of the intestines, lungs, skin and urinary system and can also be used as a mouthwash in the treatment of ulcers. Extracts of the plant contain compounds called saponins, one of which is asphonin, and can be used to effectively treat lower back pain. Between 6-12 grams of dried rhizome is normally used in water as a decoction. A qualified Chinese medicine practitioner should be seen for information on the appropriate dosages and any possible drug interactions.
