Our Immune Support Herbal Tincture is a blend of Echinacea, Astragalus & Reishi that has been formulated to help protect and restore the body. Our Immune Support blend can be used to help alleviate symptoms of colds and flus and defend against infections. How to Use: Take 2-3 ml of our organic Immune Support tincture up to 3 times per day when you are experiencing symptoms of an infection. We recommend taking the Immune Support tincture consistently, until symptoms subside, then stopping until it is needed again. Our Immune Support tincture is best taken directly beneath the tongue or in a small glass of water, but can also be consumed with tea, smoothies, elixirs and more.
