Exposure to seasonal and perennial pollens, house dust, molds and pet dander can lead to respiratory discomfort, affecting the eyes, sinuses, nose, throat and upper lung tissues to varying degrees. All-natural AllerPhase is a unique herbal formula designed especially for individuals sensitive to such discomforts. The proprietary blend of herbal extracts contained in AllerPhase works by supporting the overall health of the respiratory system, especially during seasonal outbreaks. While many of the herbs in AllerPhase are directed towards supporting a healthy immune response to seasonal respiratory triggers, AllerPhase also supports overall general immune system function. The herbs in AllerPhase have a long history of safe use in Traditional Chinese Medicine (TCM) for seasonal respiratory discomforts. AllerPhase is a non-drowsy formula that doesn't cause fatigue or fuzzy thinking. Additionally, since AllerPhase is not a CNS stimulant, the formula does not cause the “wired" sensation typical of certain OTC preparations.
