Natural Treatments for Cold and Flu
Learn about the top natural remedies to fight seasonal viruses
The common cold and influenza (flu) are caused by viruses, not bacteria. Therefore, antibiotics are ineffective. And the antiviral drugs aren't any better.
Most of the current development has focused on creating drugs that render the viruses incapable of penetrating healthy cells. But because viruses can mutate into hundreds—perhaps thousands—of forms, creating such drugs is largely ineffective.
In fact, the current drug of choice being prescribed to flu patients is the antiviral drug oseltamivir (Tamiflu). But Tamiflu has become virtually worthless in fighting seasonal flu. According to CDC data, among 1,148 seasonal flu samples tested, 1,143, or 99.6 percent, were resistant to Tamiflu.
So, if you come down with the common cold or flu, do you have real treatment options?
Fortunately, the answer is "yes." These all-natural treatment options are some of the best for treating the common cold, flu (including H1N1), and other seasonal illnesses.
- Elderberry Extract
- Eucalyptus Oil
- Castor Oil
- Zinc Lozenges
- Vitamin D
- Vitamin C
Sambucol comes from the Latin name for elderberry, which is Sambucus nigra. It is an elderberry extract from Israel and is used as a common cold and flu remedy.
Sambucol has been shown effective at inactivating viruses, which is no small feat. According to studies, sambucol is a powerful antioxidant that stimulates the immune system by increasing production of disease-fighting lymphocytes. It comes in liquid syrup or lozenge form. The recommended dosages of Sambucol are:
- Children under 1 year old: 2 tsp. daily
- Children 1–6 years old: 1 or 2 T. or 2 lozenges daily
- Children 6–12 years old: 2–3 T. or lozenges daily
- Children over 12 and adults: 4 T. or lozenges
Take the recommended dosage at the first sign of the flu and the virus should disappear within 24 to 48 hours. Since Sambucol is slightly acidic, it should be taken following meals to avoid stomach upset. If you can't find Sambucol in health food stores, it can be ordered from Sullivan Creek Distributing.
The eucalyptus tree is an evergreen tree native to Australia. The oil from the leaves has been used in cough drops, cold medicines, mouthwashes, toothpaste, detergents, and liniments for arthritic pain.
Eucalyptus oil can be toxic if taken internally. But because of the potent bactericides it contains, breathing the fumes can knock out infections in the nasal passages, sinuses, bronchial tubes, and lungs, with incredible speed. This is especially important in the fight against H1N1 because this flu infects both the upper respiratory tract and the lungs, making pneumonia a grave concern for the small subset of patients who have serious complications from this virus.
To use, put 8–10 drops of eucalyptus oil on a handkerchief and keep it close enough to your nose so that you can inhale the fumes. Or, 10–15 drops can be added to a vaporizer or to some boiling water on the stove to help ease congestion. Eucalyptus oil can be purchased in health food stores or herb shops.
Active hexose correlated compound, or AHCC, is a mushroom extract and immune system stimulator. AHCC supports the immune system by aiding your body's own natural killer (NK) cells, which provide the first line of defense for dealing with any form of invasion to the body.
AHCC increases the amount of "ammunition" NK cells have to attack pathogen-infected cells. In addition, oral ingestion of AHCC increases levels of interferon, a potent compound produced by the body that has been shown to not only increase NK activity by 300 percent or more, but also increase the activity of other key immune cells like T-cells and B-cells, as well as inhibit the replication of viruses.
AHCC is nontoxic and poses no danger or ill effect from long-term use.
For maximum effectiveness during the acute phase of the flu, take 3 grams per day. Once the NK cell activity increases and you begin to feel better, you can drop back to a dose of 1 gram per day. I suggest dividing the daily dosage, whether you're taking 3 grams or 1 gram, and take half of it at breakfast and the other half at dinnertime. The AHCC used in much of the research already conducted is sold as ImmPower.
Castor oil is a triglyceride of fatty acids. Almost 90 percent of its fatty acid content consists of ricinoleic acid, which has been shown to be effective in preventing the growth of numerous species of viruses, bacteria, yeasts, and molds.
The most effective use of castor oil is through topical packs.
Usually applied to the abdomen, castor oil packs improve the function of the thymus gland and other parts of the immune system. It does this by increasing the production of lymphocytes, the disease-fighting cells in your immune system. With more lymphocytes in your blood, your body is better able to remove toxins from your cells. In turn, your body then becomes less acidic, your organ function improves, and you have increased energy.
Here's how to make and use a castor oil pack:
- Place a heating pad on a flat surface and turn the setting to high.
- Lay a plastic garbage bag on top of the heating pad.
- Soak two or three 12-inch squares of flannel in one-half cup of cold-pressed castor oil. Place them on top of the garbage bag.
- Wrap yourself in a large bath towel to keep oil from getting on your bedding. Then place the entire pack against your body with the oil-soaked flannel next to your skin.
- Relax for an hour with the heating pad at the highest temperature you can tolerate.
- When you remove the pad, massage the remaining oil into your skin or clean it off with a quart of warm water mixed with two tablespoons of baking soda. To reuse the flannel, keep it in a plastic container in the refrigerator. Let it warm up before you use it again, and refresh it with one to two tablespoons of fresh castor oil.
Your local health food store should have cold-pressed castor oil.
Zinc gluconate lozenges have been shown to shorten the duration of common cold and flu symptoms by an average of three days compared to a placebo.
If you're coming down with something, start taking one 23 mg zinc gluconate lozenge every two waking hours. The only side effect associated with zinc is its bad taste, which can be addressed using citrus-flavored lozenges such as Cold-EEZE. Even so, this routine shouldn't be continued longer than a week because excessive zinc can eventually create a copper deficiency and weaken the immune system.
Though researchers have yet to identify precisely how this homeopathic remedy works, its results are amazing when taken at the first sign of flu. Oscillococcinum is especially good for children.
Packaged in individual doses of little pellets that dissolve under the tongue, it's easy to take, has a pleasant taste, and is gentle, safe, and nontoxic.
Echinacea angustifolia is an herb that has been shown to significantly increase certain immune responses and inhibit viral activity such as the flu. Research indicates that echinacea binds to receptors on the surface of white blood cells, literally turning these immune cells "on."
I recommend using the liquid plant extract. For adults, put 5–10 drops in ¼ cup of water and take 5 times daily.
At the first sign of flu, up your daily vitamin D dose to 1,000 IU per pound of body weight per day for a week. Example:
170 pounds x 1,000 IU vitamin D = 170,000 IU daily
Continue this protocol until symptoms improve, and then scale back to your maintenance dose.
Loading up on vitamin C beyond your daily maintenance dose provides extra immune support during a bout of the flu. In addition to its own antiviral activity, vitamin C also—
- Protects white blood cells
- Boosts levels of virus-fighting interferon and natural killer cells
- Fortifies the mucous membranes
- Has its own antiviral activity
At the first sign of illness, take 500–1,000 mg of vitamin C every waking hour. To avoid possible gastrointestinal upset, build up gradually by taking 500 mg every two hours on the first day and moving up to the higher dose on the second day. Take no more than 10,000 mg per day, and ease back to your usual dose as symptoms improve.
