Summarize the following:
Although herbs are generally safe, they aren’t right for everyone. Some herbal remedies may interact with certain medications, and they may aggravate an underlying condition. Check with your doctor to be sure that herbal remedies are safe for you to use for a cold. It’s always best to check with your doctor before using any type of supplement or treatment. Normally, you won’t need to visit a doctor for a cold. Since colds are a viral infection, antibiotics won’t treat them. However, a severe cold might require medical treatment. See your doctor if you have a fever or a severe sore throat, congestion, or sinus pain.  A fever is considered high if it’s greater than 101.3 °F (38.5 °C) for adults or 100.4 °F (38.0 °C) for newborns. A child may also experience ear pain, fussiness, extreme drowsiness, and lack of appetite. If your child has these symptoms, take them to the doctor. While you shouldn’t worry, these symptoms can be serious. Always see your doctor if you’re having trouble breathing normally. They can make sure you’re okay and give you treatments to improve your condition. Make a same-day appointment with your doctor or visit an urgent care center or emergency room. You’re likely going to be okay, but you may need treatment to improve your breathing.

Summary:
Check with your doctor before using herbs. Visit your doctor if you have a persistent cold, a fever, or severe cold symptoms. Get immediate care if you experience shortness of breath or wheezing.
