Which remedies are used for colds and allergies?
Inhalation devices, nasal irrigators, and light therapy devices are used for colds and allergies. Inhalers nebulize liquids into fine aerosols that reach the airways. Nasal irrigators mechanically flush pollen, dust, and mucus from the nose. Light therapy devices use red and infrared light to provide support, for example in cases of allergic rhinitis.
