Made with Boneset and Yarrow infused in alcohol. Boneset is often used to treat influenza, swine flu, acute bronchitis, nasal inflammation, joint pain (rheumatism), fluid retention, dengue fever, and pneumonia; as a stimulant; and to cause sweating. Yarrow is used for fever, common cold, hay fever, dysentery, diarrhea, loss of appetite, gastrointestinal (GI) tract discomfort, and to induce sweating. I have been using these herbs together for 30 years, as taught to me by my teacher Rosemary Gladstar, and I love how they can break a fever.
