5 of the Best Herbs to Boost the Immune System

2. Elderberry for immune system

People with weakened immune defense may be more prone to frequent colds, flu, or upper respiratory infections. While antiviral medications are commonly prescribed for severe flu or infections, elderberries are thought to be a natural remedy.

Elderberries are the fruit of the Sambucus nigra L. tree and are grown in many countries. There are also a variety of species. The fruit and leaves are packed with vitamins and antioxidants that may boost your immune system. Elderberry tea, for example, has traditionally been used for building immunity against the common cold and influenza. And its naturally mild, sweet flavor makes it tolerable, even with the earthy notes.

Herbal infusions made from the plant were also used for treating gastrointestinal problems, regulating body temperature during a fever, and opening up the pores for sweating. In fact, one study shows that elderberry extract lozenges may reduce the severity and duration of cold and flu symptoms such as fever, chills, and sweating.1✅ JOURNAL REFERENCE

That’s because the plant has antibacterial and antiviral properties.

Further, Sambucus nigra L also shows antioxidant, anti-inflammatory, and immune-modulating activities in the body. According to researchers, elderberry juice has the ability to prevent and fend off viral infections such as the flu by stimulating immune response.2✅ JOURNAL REFERENCE

The herb’s ability to fight off infections is tied to its high levels of antioxidants and other phenolic compounds. The antioxidants and anti-inflammatory agents also work to combat oxidative stress during immune system response to invasion.
