Influenza can affect the upper respiratory tract or the digestive tract and is characterized by intense aches and pains, vomiting, diarrhea, fever and headache. The flu is a virus and not responsive to conventional medicines like antibiotics. However, many of its symptoms may be relieved by herbal remedies. Herbs can soothe pain, stop stomach upset and speed overall recovery. Herbs may also produce side effects, so consult a health practitioner before using herbal remedies for flu.
Echinacea
Echinacea has anti-viral properties and is used as an immune system enhancer, according to the University of Maryland Medical Center. The herb has traditionally been employed to reduce inflammation and cleans the blood, says "The Green Pharmacy Herbal Handbook." Echinacea is available in various forms, ranging from dried, powdered capsules to standardized extracts. The extracts are generally more potent, but not all brands are equal. Buy only recognized brands from reputable health food stores where the product moves regularly so it is always freshest. Do not use echinacea in any form if you take immunosuppressants. Consult with a health practitioner for dosing guidelines.
Garlic
Garlic is another immune-enhancing herb, used for thousands of years across the globe. It is known for its ability to fight infections, whether bacterial or viral, says the Linus Pauling Institute. Garlic is available dried in capsules, as an extract and fresh. If you use dried garlic, avoid taking tablets, which are heated during manufacture and lose their potency. The best dried form for garlic, which helps retain its potency is freeze-dried. One of the best methods for consuming garlic to relieve a stomach flu is as an herbal tea. To make the tea, peel two cloves of garlic and crush. Add to 2 cups water and boil for five minutes. Lower the heat and simmer for 15 minutes. Remove from the heat and strain. Add honey to taste and drink to settle an upset stomach, halt vomiting and soothe painful intestines. Garlic can thin the blood. If you take blood-thinning medicines, talk with your health practitioner before using it medicinally.
Chrysanthemum Tea
Chrysanthemum tea is widely used in China to purify the blood and remove toxins, according to the City University of New York. In addition to clearing blood toxins, the tea soothes and comforts. It helps fight insomnia, allowing the person to rest and recover from the ravages of severe flu. Along with its blood-purifying properties, it is thought to act as an antibiotic, relieving secondary infections that may develop alongside the flu, says the "Helio Acupuncture Book, Chinese Herbal Medicine: Materia Medica." Some people may be allergic to chrysanthemum flowers, developing a rash or swelling of the mouth, tongue or throat. If you develop any symptoms, stop using it at once and seek medical assistance.
Elderberry
Elderberry not only helps in cases of flu with respiratory involvement but also aids in relieving symptoms of stomach flu, according to "The Green Pharmacy Herbal Handbook." Elderberry enhances the immune system, often stopping a case of flu before it fully blooms. It is necessary to start taking elderberry extract immediately, at the first sign of symptoms for it to act quickly on the system. Consult with your health practitioner before using elderberry. Straight elderberry extract and mixtures containing the extract are available at health food stores.
