Oral oseltamivir is recommended for treatment of pregnant people with flu because compared to other recommended antiviral medications, it has the most studies available to suggest that it is safe and beneficial during pregnancy. The researchers tested the drugs in lung cells as well as in mice, and found that these combinations were highly effective against multiple strains of the coronavirus, including the delta variant.
The team is now in the process of testing the drugs against omicron. This work was supported by grants from the National Institutes of Health R01AI, R01AI, 1R21AI, R01AI , as well as funding from the Penn Center for Precision Medicine, Mercatus, and the Bill and Melinda Gates Foundation.

It has been deemed a miraculous compound for restraining virus replication and virus development. A 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.

A 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. Turkey tail mushroom is well-known for its ability to stimulate immune function.
It contains polysaccharides that have immune-boosting power when consumed. When researchers evaluated the immune-modulating effects of turkey tail, they found that it was able to increase antiviral cytokines and had modest effects on growth factors.
Research also suggests that turkey tail is effective against an oral strain of the human papillomavirus HPV. When it was used in combination with reishi during the 2-month treatment period, the mushrooms improved results in 88 percent of patients. The most common ways to use turkey tail is in capsule, powder or tea form.
Medicinal mushrooms are rising in popularity and can be found easily in your local health food store. It helps to bring the body back to homeostasis and regulate immune function. Reishi contains two powerful compounds, polysaccharides and triterpenes, which are known for their ability to enhance the immune response and reduce inflammation.
Studies highlight the antiviral effects of turkey tail compounds that are able to block the absorption of virus to the cells. You can easily find reishi and other medicinal mushrooms in capsule and powder forms in your local health food store.
Licorice root is emerging as a prominent player in the search for treatment and prevention for diseases like hepatitis C, HIV and influenza. The Chinese Journal of Virology published a review that confirms the antiviral activity of licorice root due to its triterpenoid content.
The olive leaf has antiviral properties, giving it the ability to treat the common cold and dangerous viruses, including candida symptoms , meningitis, pneumonia, chronic fatigue syndrome, hepatitis B, malaria, gonorrhea and tuberculosis; it also treats dental, ear and urinary tract infections and is a natural treatment for shingles.
Research shows that olive leaf extracts effectively fight against a number of disease-causing microbes, including some viruses that cause influenza and other respiratory infections.
In fact, the olive leaf is so beneficial to our health that treatment with olive leaf extracts reversed many HIV-1 infection-associated changes in a study done at the New York University School of Medicine. Oregano is a powerful antiviral agent.
Medicinal grade oregano is distilled to extract the essential oil and preserve its healing compounds; in fact, it takes over 1, pounds of wild oregano to produce just 1 pound of oregano oil!
Oregano oil benefits are proving to be superior to some antibiotics, without the harmful side effects. Sage is an essential ingredient in traditional Chinese medicine and Ayurvedic medicine.
Traditional herbalists value sage for its ability to help fight infections and improve a number of ailments. Research illustrates that sage has antiviral, antioxidant and anti-inflammatory effects.

Moreover, we suggest targeting the receptors of SARS-CoV and SARS-CoV-2 such as ACE2 and other proteins including 3CLpro and PLpro for improving antiviral activity and immune response against COVID disease. Additionally, since phytochemicals play an essential role in complementary therapies for viral infections, we summarized different bioactive natural products against the mentioned respiratory viruses with a focus on influenza A, SARS-CoV, MERS, and COVID Based on current literature, compounds have antiviral potential, and of these, 94 metabolites demonstrated bioactivity against coronaviruses.
