Echinacea, a popular herb in traditional medicine, is known for its immune-boosting properties. Research shows that it enhances the activity of white blood cells, which are crucial for fighting infections. A meta-analysis of randomized controlled trials suggests that Echinacea can reduce the duration and severity of upper respiratory infections, such as the common cold, by stimulating immune cell activity. Its antiviral and anti-inflammatory properties make it a staple in herbal remedies for seasonal illnesses. (Source)

2. Elderberry (Sambucus nigra)

Elderberry is a rich source of antioxidants and flavonoids, which support immune health. Studies have demonstrated its effectiveness in reducing the duration and severity of influenza symptoms. A 2019 randomized clinical trial published in Complementary Therapies in Medicine found that elderberry extract can significantly shorten flu recovery times. This herb also helps modulate inflammatory responses, providing an added layer of protection against infections. (Source)

3. Astragalus (Astragalus membranaceus)

Astragalus has been used in traditional Chinese medicine for centuries to enhance immunity. Modern research confirms its immunomodulatory effects, showing that it strengthens the body's resistance to infections by boosting the production of immune cells like T-cells and macrophages.
