A teaspoon of honey and lemon juice helps soothe the throat. Gargling with salt water is also beneficial. Running a hot shower creates steam to help moisten and clear nasal passages, and taking a warm bath can help relieve aches and pains.
Run a humidifier or oil diffuser. Eucalyptus oil and peppermint help loosen up mucus and assist with relieving congestion.
Plenty of rest and liquids like ginger tea, chicken soup, and water are always a good idea.
Look to holistic medicines with natural, herbal ingredients. Elderberry, Vitamin C, Echinacea, and more. Of course, if a cold worsens, seek medical help.
