Herbs for Infection and Flu You Should Know

10 Herbs for Infection and Flu You Should Know

Infection occurs when a microorganism enters the body and causes harm to human health. The causes of the disease can come from bacteria, viruses, fungi, or other pathogens.

Current conventional treatments are antibiotics and antivirals, but some people are turning to herbal treatments because of their potential antibacterial properties.

Here are the best herbs for infections that will help strengthen the immune system and prevent viruses.


What are Herbs and How can they help with Infections?

10 Herbs for Infection and Flu

Herbs are natural remedies derived from plants that prevent and treat viral respiratory infections (VRI) like the common cold, flu, and bronchitis.

They offer alternatives to conventional treatments, which often only mask symptoms and may have limited efficacy.

Herbs can potentially directly target viruses, modulate immune responses, and alleviate symptoms, so herbs provide a holistic approach to managing VRI.

Additionally, they offer evidence-based prevention strategies, which is especially important given the limitations of influenza vaccines and the low vaccination uptake in the population. [1]

Herbs can combat infections in various ways: [1]

  1. Direct Antiviral Action: Certain herbs contain compounds that directly inhibit the replication of viruses causing respiratory infections. For instance, herbs like Ligusticum spp., Lomatium dissectum, and Osmorhiza occidentalis are potent antivirals, especially effective against respiratory tract viruses.
  2. Immune Stimulation: Many herbs boost immune-stimulating properties, aiding the body's natural defense against viral infections. Herbs like Sambucus nigra (black elderberry) and Panax ginseng enhance immune function, reducing the likelihood and severity of viral infections.
  3. Inflammation Modulation: Infections often trigger inflammatory responses, leading to symptoms such as fever, sore throat, and cough. Some herbs have anti-inflammatory effects that can alleviate these symptoms and prevent complications from excessive inflammation. For example, herbs like Prunella vulgaris and Glycyrrhiza glabra show inflammation-modulating properties.
  4. Symptom Relief: Certain herbs provide relief from discomfort linked to respiratory infections. For example, Echinacea angustifolia and Lomatium dissectum are traditionally used to ease symptoms like cough, sore throat, and nasal congestion.

Overall, herbs offer a comprehensive approach to managing viral respiratory infections by targeting the virus, boosting the immune system, controlling inflammation, and relieving symptoms.

Specific Herbs for Infections

Fungal Infections

Goldenseal Root

Goldenseal can help combat fungal infections

Goldenseal can help combat fungal infections through the presence of endophytic fungi.

Specifically, research has identified endophytic fungi from the goldenseal plant and the secondary metabolites they produce that have antibacterial properties.

One of these compounds is Alternariol monomethyl ether, which is detected in both Alternaria spp—fungi and in the seeds of the goldenseal plant.

Although extracts from goldenseal seeds do not exhibit antibacterial activity, these compounds from endophytic fungi may play a role in combating fungal infections. [2]

Turmeric, specifically its essential oil (TEO) and aloe vera gel (AVG), contains bioactive compounds that combat fungal infections.

These compounds enhance the effectiveness of antifungal creams (AFCs), such as terbinafine and azole creams, against various pathogenic fungi.

The synergistic action of TEO or AVG with AFCs shows promise as an alternative treatment for fungal infections, offering a potent and side-effect-free solution, particularly for dermatophytosis and other common fungal diseases. [3]

The research explored Myrrh essential oil's antifungal properties against three storage fungi: Aspergillus flavus, A. niger, and Penicillium citrinum.

Findings indicated that the oil hindered fungal growth, sporulation, and spore germination in a concentration-dependent manner.

Additionally, the vapor of Myrrh essential oil exhibited inhibitory effects on the fungi.

These results propose that Myrrh essential oil could be a promising natural antifungal agent for managing storage fungi. [4]

Cardamom (Elettaria cardamomum)

Elettaria cardamomum, popularly referred to as cardamom, exhibits great potential in the fight against fungal infections.

Strong substances with antibacterial qualities, such as flavonoids and polyphenolic acids, are present in its ethanolic extract (EEC).

Research has indicated that EEC may efficiently suppress fungal growth, exhibiting inhibitory zones that span from 8 to 33 mm in diameter.

EEC's broad-spectrum antifungal activity underscores its potential as a natural therapy for fungal diseases, even though susceptibility varies amongst fungus strains.

Bacterial Infections


The study explored oregano's antibacterial potential against 111 Gram-positive bacterial isolates from 23 species across 3 genera.

Results: oregano infusion and essential oil were effective against bacteria like Staphylococcus saprophyticus, S. aureus, Micrococcus spp., and Bacillus spp.

Infusion worked best on Bacillus laterosporus, while the oil was most effective on S. saprophyticus.

However, oregano decoction showed no antibacterial activity. This highlights oregano as a natural antibacterial agent against Gram-positive bacteria. [5]

Extensively studied for its medicinal properties, garlic stands out for its antimicrobial, cardiovascular, and anti-cancer effects.

Packed with sulfur compounds and active elements like allicin, it boasts therapeutic advantages.

Garlic has been a go-to remedy in diverse cultures through the ages, and modern research is unveiling its vast health potential.

From battling infections to reducing blood pressure and cholesterol, garlic is hailed as a natural powerhouse for enhancing overall health and well-being. [6]

Garlic stands out for its antimicrobial


Thyme helps fight infections using biological compounds in thyme oil, especially vital active ingredients such as thymol and carvacrol.

These compounds have been shown to inhibit bacterial growth and have vigorous antibacterial activity, especially against drug-resistant bacteria. [7]

Viral Infections


Elderberry helps with viral infections through its rich content of flavonoids, particularly anthocyanins.

These compounds have been shown to possess antiviral properties by interfering with the replication of viruses, thus helping to reduce the severity and duration of viral infections.

Elderberry may be a safe option for treating viral respiratory diseases. However, its effectiveness and safety are still uncertain, and more research is needed to draw solid conclusions. [8]

The study investigated the antiviral properties of peppermint, focusing on its potential against herpes simplex virus (HSV).

It found that both dichloromethane and methanol extracts of peppermint, as well as pure menthol, effectively inhibited HSV replication in green monkey kidney cells. [9]

Multiple studies have demonstrated the significant antiviral properties of various peppermint extracts.

Peppermint appears to bolster the immune system and provide protection against viruses. [10]

Ginger (Zingiber officinale) has been found to exhibit antiviral properties primarily through its bioactive compounds, such as gingerol, shogaol, and paradol.

These compounds have demonstrated antiviral activity against various viral infections.

Ginger's antiviral effects are attributed to its ability to inhibit viral replication, interfere with viral attachment and entry into host cells, and modulate immune responses to combat viral infections. [11]

Precautions When Using Herbs for Infections

When using herbs to treat infections, there are some important considerations to remember:

  • Seek Medical Guidance: Before incorporating herbs into your regimen, consult your healthcare provider for tailored advice on herbal treatments that align with your health needs.
  • Select Appropriate Herbs: Different herbs offer varying properties. Opt for herbs that best address the specific infection you are dealing with, considering factors like antibacterial strength or immune support.
  • Prioritize Product Quality: Choose herbal products from reputable sources that adhere to rigorous testing and quality standards.
  • Adhere to Dosage Instructions: Follow dosage guidelines on product labels or as advised by healthcare professionals to avoid adverse effects. Always consult before adjusting dosage or usage methods.
