Andrographis is one of the most popular medicinal plants that has been used for centuries in America, Asia and Africa. It possesses powerful compounds that have antiviral, antimicrobial, antioxidant and anti-inflammatory effects.
Traditionally, andrographis was used for influenza and malaria. Today, researchers have explored andrographis as a potent antiviral remedy. It has been deemed a miraculous compound for restraining virus replication and virus development.
A 2017 study published in Microbes and Infection found that when andrographolide (the active ingredient in andrographis) was given to mice with the influenza virus, along with a virus entry inhibitor, the combination increased survival rate, diminished lung pathology, decreased the virus load, and reduced inflammatory cytokines.
Andrographis is available in capsule and tincture forms, and it can be found online or in most health food stores.
Experiments have shown that garlic — or specific chemical compounds found in garlic — is highly effective at killing countless microorganisms responsible for some of the most common and rarest infections, including tuberculosis, pneumonia, thrush and herpes.
Not only is it one of the best antiviral herbs for herpes, but its properties also help to treat eye infections and it works as a natural ear infection remedy.
Some more raw garlic benefits include its ability to reduce the risk of cancer, control hypertension, boost cardiovascular health and fight hair loss.
To make a garlic oil infusion at home, crush garlic cloves and add them to a carrier oil (like olive oil). Let the mixture sit for about five hours, and then strain the bits of garlic and keep the oil in a jar with a lid. This infusion can also be used as an antiviral herb for cold sores when used topically.
You can also swallow a raw clove of garlic; you might need to cut it in half if it’s too large. Bite down once to release the allicin; then swallow with water like a pill.
5. Astragalus Root
Astragalus root, another powerful antiviral herb, has been used in traditional Chinese medicine for centuries, and its main use is to boost the body’s immune system. Scientific studies have shown that astragalus has antiviral properties and stimulates the immune system, suggesting that it may help remedy the common cold or flu.
It’s one of the most effective antiviral herbs for HSV. A 2004 study evaluated the effects of astragalus on herpes simplex virus type 1 and found that the herb has obvious inhibiting efficacy.
Another study published in the Chinese Medical Sciences Journal concluded that astragalus is able to inhibit the growth of coxsackie B virus in mice.
Not only does it work as a natural viral infection treatment, but astragalus also has antibacterial and anti-inflammatory properties, and it is used on the skin for wound care. It’s also one the adaptogen herbs to lower cortisol.
