Spectrumceuticals TriHerb Oral Liquid is a practitioner-formulated blend of three powerful herbal extracts – Echinacea purpurea, Andrographis paniculata, and Olea europaea (Olive leaf). This synergistic combination is designed to support immune system health, particularly during cold and flu season or times of increased susceptibility to mild upper respiratory tract infections. Echinacea has traditionally been used in Western herbal medicine to support immune system function and relieve symptoms of mild infections. Andrographis is known for its ability to reduce the severity and duration of common colds, while Olive leaf provides antioxidant support and helps maintain general wellbeing. Conveniently delivered in a 50mL oral liquid format, this formula allows for flexible dosing and rapid absorption.
