Putting The Knowledge To Work
With so many options to work with we recommend choosing at least one herb from each category and set your intention to incorporate each of these into your weekly routine. For example, I would opt for using Eucalyptus Oil as aromatherapy and steam breathing and compliment that with eating more oregano, ginger and thyme while also drinking peppermint and green teas. Using the Zen Haus Immune Support supplement will provide you with non-GMO Echinacea, Black Elderberry and Olive Leaf Extract. Then you will have covered nine traditional herbal remedies used around the world. You will also have the immune system benefits of Zinc, Magnesium and Quercetin included in the supplement.
