According to the Herbal Research Foundation, echinacea is useful in stimulating the immune system. While this may not necessarily cure your cold, it may help prevent a cold in the first place. Because echinacea stimulates the overall activity of infection-fighting cells, it is helpful in treating a wide range of infections including viruses and bacteria.
Some studies have shown that the herb can be helpful in treating upper respiratory tract infections, and it has been used as an immune system booster for people undergoing cancer treatment.
Other uses of echinacea include: Treating urinary tract infections:
• Speeding wound healing (when used externally).
• Reducing sore throat pain or enlarged lymph glands.
• Aiding in healing of skin conditions such as eczema or inflammation (when used externally).
• Fighting infections.
• Killing germs and reducing pain from external injuries.
