Ginger, honey, echinacea and salt water are common home remedies, states Healthline. These remedies aid in relieving cold and flu symptoms, and they boost overall health.
Garlic contains allicin, a compound that prevents viral and bacterial infections, notes Healthline. Taking garlic reduces symptoms related to the common cold, and adding garlic to the diet reduces the risk of contracting the cold and flu virus. Honey has antimicrobial and antibacterial properties, and it also suppresses coughs and eases sore throats. Children under 1 year of age should not consume honey to prevent adverse effects from its botulism spores.
Chemicals in echinacea reduce the duration of colds and flu, reduce inflammation in the body and boost the immune system, according to Healthline. Adults should take 1 to 2 grams of echinacea root in tea form three times daily, but they should not drink the tea for longer than one week. Gargling and swishing a salt-water solution made by dissolving 1 teaspoon of salt in one glass of water loosens and releases from the body mucus that holds allergens and bacteria. Salt water used with a neti pot also relieves nasal congestion. Gargling with salt water reduces and prevents upper respiratory infections and relieves a sore throat.
