Quercetine – the Immune System Builder
Quercetin is a fabulous bioflavonoid antioxidant found in many healthy foods including apples, onions, red wine, cocoa, dark cherries & berries, grapes, leafy greens & broccoli, beans, green teas, elderberries, sage, gingko biloba, and even St. John’s Wort.
Quercetin helps build endurance for healthy immune system function. This powerful antioxidant acts as an anti-inflammatory and anti-viral, which can be helpful for chronic fatigue, allergies, infection, and arthritis. It promotes proper cell functioning and healthy immune response to outside stressors. Also there are some studies showing quercetin to stimulate brain neurogenesis.
In 2014, researchers noted that quercetin appears to be “a promising treatment for the common cold,” caused by the rhinovirus, adding that “quercetin has been shown to reduce viral internalization and replication in vitro, and viral load, lung inflammation and airways hyper-responsiveness in vivo.
Previous research shows that quercetin’s antiviral capacity works in three ways. Quercetin can:
- Stop the virus from infecting cells
- Reduce the reproduction of cells that are already infected
- And reduce infected cells resistance to treatment with antiviral medications

What is Elderberry?
Elderberry is native to Europe, Africa and parts of Asia, but it is become common in the U.S. It has deciduous leaves, white flowers (elderflowers) and berries that turn from green to red to black when ripe. It is commonly found growing in woodlands and hedgerows.
There are about 30 types of elder plants and trees found around the world. The European version (also known as Sambucus nigra) is the one most closely tied to your health and healing. Its history dates as far back as 400 BC, and Hippocrates, the “Father of Medicine,” called the elder tree his “medicine chest.”
In folk medicine today, the elderberry is widely considered one of the world’s most healing plants.
