Group 2: Antibiotic and Antiviral Use - Antibiotics are ineffective against colds, which are typically caused by viruses, and should only be prescribed for confirmed bacterial infections [4][5]. - Antiviral medications should not be misused; they are generally only prescribed within 48 hours of a confirmed flu diagnosis [5]. Group 3: Special Population Considerations - Elderly patients should be cautious with medications containing pseudoephedrine due to potential impacts on blood pressure and heart conditions [5]. - Pediatric medications should be specifically formulated for children rather than simply reducing adult dosages [5]. - Pregnant women are advised to consult healthcare professionals before taking any medications to avoid unnecessary risks [5].

Group 2: Acupressure Techniques - High Feng recommended acupressure on two specific points: the Fish Border Point and the Taiyuan Point, which can help alleviate cough symptoms when pressed for 3 to 5 minutes until a slight soreness is felt [4]. - A preventive method suggested by High Feng involves washing the sides of the nose with cool water each morning and pressing the Yingxiang point to enhance respiratory defense and adapt to cold air [4].
