5 Tonic Herbs to Boost Immunity This Winter

The cold months of the year bring a flurry of beastly germs to our doorstep. These wee-but-wicked pathogens must sense that our immune systems are vulnerable—especially during the holidays, when rich food and drink prevail. I like to start bolstering my family’s immune systems early in the cold & flu season; well before everyone around us is sniffling and sneezing. Practices like eating a nourishing diet; getting plenty of sleep, sunshine, and water; and proper hand washing are essential, but I also rely on a handful of tonic herbs to keep us healthy and resilient.

Herbs for the Immune System

Before we dive into herbs for the immune system, we’re going to start with lifestyles for the immune system. Because herbs are really and truly the icing on the cake, whereas the day-to-day choices we make for how we want to live are the cake, so to say.

Violet blooms.

Violet’s Edible and Medicinal Uses

Violets are welcome “weeds” in my garden. In fact, the common blue violet—my particular brand of violet garden guest—is native to these parts, which is more than I can say for myself. The common blue violet (Viola sororia, Violaceae) is native to most of central and eastern North America. It is a common sight in lawns, gardens, sidewalk cracks and along trailsides. The common blue violet is typically considered a “weed” because of its relative ease in adapting to human disturbance, but it pushes the definition of weed because it has been on this continent for a very long time. The leaves and flowers of the common blue violet, along with many other species, are edible and medicinal. The “confederate violet” is an escaped cultivar (cultivated variety) of Viola sororia—it has white flowers with blue streaks and is a common inhabitant of lawns in the southeastern United States.
