In TCM, preventing colds and flu depends on the strength of 'Wei Qi' (衛氣) or defensive energy, which acts like armor protecting the body from external pathogens. People with strong Wei Qi have good immunity—they rarely catch colds, and if they do, they recover quickly.
A classic Chinese herbal formula for immune support, used for over 800 years, is 'Yu Ping Feng San' (玉屏風散) or 'Jade Windscreen Powder.' It contains three herbs, with the chief ingredient being Huang Qi (黃芪/Astragalus), which boosts energy and strengthens the lungs. It's ideal for those who catch colds frequently or want to boost immunity before winter.
When cold symptoms begin, popular Chinese formulas include 'Yin Qiao San' (銀翹散) for colds with fever and sore throat, and 'Gan Mao Ling' (感冒靈) for general colds. These formulas have antiviral properties and help relieve symptoms. Starting treatment within the first 24 hours yields the best results.
Acupuncture for immune support can help prevent colds by stimulating points related to white blood cell production and immune system balance. It also relieves cold symptoms like congestion, body aches, and fever. Regular acupuncture sessions before winter helps prepare the body for the season.
TCM self-care recommendations include eating warming foods like ginger congee, herbal soups, and bone broth; avoiding cold foods and raw items; getting adequate sleep; keeping the neck, back, and feet warm; washing hands frequently; and avoiding crowded places during outbreaks.
