Colds and flu are two distinct conditions even though they have similar symptoms, including cough, sore throat, stuffy nose and fatigue. According to the American Academy of Family Physicians, the onset of flu is typically much more sudden than that of the common cold, which tends come on gradually. Both colds and flu are caused by viruses. Certain herbs may help, but if your symptoms are extreme or long-lasting, consult a health care professional.
Astragalus
Nutritional consultant Phyllis Balch recommends astragalus for both colds and flu in her book, "Prescription for Nutritional Healing." Astragalus is described by the University of Maryland Medical Center as an adaptogen, an herb that helps defend the body against physical, mental, and emotional stress. It is used in traditional Chinese medicine not only for colds and flu but for infections, allergies, asthma and fevers. Astragalus is rich in antioxidants, substances that help prevent cells from being damaged by harmful free-radicals. It also has anti-inflammatory and antibacterial properties. Consult a qualified health care professional about whether astragalus is right for you.
Slippery Elm
Slippery elm was used by Native Americans as both a topical salve for wounds, boils and burns, and as an oral medicine for gastrointestinal problems, coughs and sore throats. It is an ingredient used today in some cough drops and lozenges. When the inner bark of the slippery elm tree is powdered and mixed with water, it forms a gel that soothes the mouth and throat when taken orally. It is sold as a tea, a tincture and in capsules. The University of Maryland Medical Center advises that slippery elm is not associated with serious side effects. However, it may inhibit the absorption of drugs and other herbs. Use slippery elm under the supervision of your physician, especially if you are taking any medications.
Cat's Claw
"Prescription for Nutritional Healing" suggests cat's claw for reducing the duration of flu and for alleviating cold symptoms. The National Center for Complementary and Alternative Medicine at the National Institutes of Health says that the medicinal use of cat's claw dates back to the civilization of the Incas. This herb grows in the tropical rainforests of Central and South America. The inner bark and root are the parts of the plant used for medicinal purposes. Today, it is sold in extract, tea and capsule form. Side effects are uncommon, but may include vomiting, headaches and dizziness.
