These herbal combinations are designed to enhance the body‘s immune system. They are useful for most infections. Dr. Rydland has used this combination of herbs for nearly every type of non-serious infection. We recommend taking it at the beginning of symptoms such as cold, flu, fever, ear infections, viruses, etc. (except when the child is vomiting)and as a preventative when exposed to illness or when traveling. In our experience, this will speed up the recovery from the disease and decrease the likelihood of it becoming a more serious infection when taken for an illness. Use as a preventative, in our experience, will decrease the likelihood of severe disease and may prevent it. A physician should carefully monitor all infections.
