1. Purple Echinacea and the Immune System

Echinacea purpurea is best known for its ability to enhance the immune system.

• Immunostimulant Effects: Research in "Immunopharmacology and Immunotoxicology" indicates that Echinacea stimulates the immune system by increasing the activity of immune cells like macrophages and natural killer cells【1】.
• Application in Immune Disorders: Its immunostimulant properties make it a potential adjunct treatment for immune system disorders.

2. Echinacea in Preventing and Treating Colds

One of the most common uses of Echinacea is in the prevention and treatment of the common cold.

• Use as a Prophylactic Treatment: Regular consumption of Echinacea supplements during cold seasons is believed to help in preventing colds.

3. Antiviral Properties

Echinacea’s effectiveness against colds is partly due to its antiviral properties.

• Inhibiting Viral Replication: The "Journal of Medicinal Food" reports that Echinacea contains compounds that can inhibit the replication of viruses responsible for the common cold【3】.

4. Echinacea and Respiratory Health

Apart from colds, Echinacea is beneficial for overall respiratory health.
