Antiviral Activity of Essential Oils: It's Never too Early for Good Health

It's started to rain here in Portland, a not-so-subtle reminder that fall is on the way. It seems this time of year usually comes with a spike in seasonal colds and flu, as well as the gray-scape of clouds. Not so fun!

Before the season sets in, you may want to take stock of your essential oil inventory at home. Do you have the basics--like eucalyptus, lemon balm, and peppermint--which are thought to help kill airborne viruses when diffused into the air? These essential oils can also be added into hand creams to help stop the spread of infection through person-to-person contact.*

For more health-promoting tips this pre-fall season, check out ACHS Academic Dean Dr. Arianna Staruch's article about the antiviral activity of essential oils: http://www.achs.edu/news/news-detail.aspx?nid=193

You also may want to visit the Apothecary Shoppe, where most essential oils have posted information about their traditional use and wellness support, and some even include blending formulas.

Here's the recipe to prepare an inhalation from the eucalyptus webpage:

Alcohol, 90%: 4.5-cups
Eucalyptus Eucalyptus globulus oil: 6-t
Thyme Thymus vulgaris oil: 3-t
Pine Pinus sylvestris oil: 3-t
Lavender Lavandula angustifolia oil: 2-t
Lemon Citrus limon oil: 2-t

Mix all ingredients. To prepare as an inhalation, add 3-t to 6-cups of boiling water. This mixture can also be added to the bath water or to footbaths. Use 3-drops in the bath or 1-2-drops in a footbath.

The antiviral activity of essential oils

BY Arianna Staruch, ND, ACHS Academic Dean

A recent study looked at preparing a nasal spray from the essential oil of bupleurum root (Radix bupleuri) and tested it in animals for effectiveness. It did show promise as a fever reducer. However, many essential oils can be irritating to mucus membranes and should not be used undiluted or without first doing a skin patch test.

So how can you use essential oil in your everyday life to help reduce to risk of viral infection? Essential oils can be used in the home as antiviral cleaning products. A diffuser with any of the oils listed above, such as eucalyptus, lemon balm, or peppermint, may reduce the airborne viruses in a room. In addition, essential oils may be added to hand creams to help reduce the spread of viruses by contact. Of course, these should be used in addition to the common sense CDC recommendations to wash your hands frequently, cover your mouth and nose with your arm when you sneeze, and to stay home if you are sick. (You should see your primary care provider for a proper diagnosis if you think you may have the seasonal flu or the H1N1 flu, and follow their recommendations.) This fall may be a challenging time because there is the potential for many people to be sick with the flu at the same time, but we can use natural support options, such as essential oils, to keep us healthy.

Herbs used around the world to protect against swine flu

The October issue of HerbalEGram features an article about how herbs like holy basil (Ocimum tenuiflorum) are being used in countries worldwide to help protect against swine flu. The "International Report on Herbs and Swine Flu" cites statistics from a recent World Health Organization report: "More than 300,000 people around the world are estimated to have contracted Influenza A(H1N1) virus, and at least 3,917 people have died from it." Though a shortage of vaccination is not expected in the U.S., many developing countries will not be able to supply the demand of the their population and as a result "some in these nations are turning to medicinal herbs with immune-boosting properties in attempts to help protect against the virus."

In Bangalore, for example, "people are purchasing Indian tinospora (Tinospora cordifolia), a deciduous climbing shrub with anti-inflammatory and anti-allergic effects, and immune-boosting properties." In addition, in the "Indian tribal district of Dangs, where medicinal plants grow throughout the forests, the health department is giving tourists an herbal drink also containing Indian tinospora. Prepared by local Ayurvedic doctors, the drink also contains holy basil (Ocimum tenuiflorum), which exhibits adaptogenic, anti-inflammatory, and antioxidant activities, and ginger (Zingiber officinale) root, which has anti-nausea and anti-inflammatory effects and also aids digestion."

H1N1 influenza pandemic updates from the World Health Organization

The World Health Organization (WHO) recently released a series of updates about what they are calling the H1N1 influenza pandemic.

WHO updates included information about steps that schools can take to minimize the spread of H1N1, as well as general information about preparing for a second wave of outbreak.

According to the WHO website, “Experience to date has demonstrated the role of schools in amplifying transmission of the pandemic virus, both within schools and into the wider community. While outbreaks in schools are clearly an important dimension of the current pandemic, no single measure can stop or limit transmission in schools, which provide multiple opportunities for spread of the virus.”

Instead of a single solution, WHO recommends that in addition to measures taken by national and local authorities, all students, teachers, and staff who feel unwell should stay home. And, in case there is incidence of illness at school, there should be plans in place to isolate the illness.

The primary health benefit of proactive measures like these is “slowing down the spread of an outbreak within a given area and thus flattening the peak of infections. This benefit becomes especially important when the number of people requiring medical care at the peak of the pandemic threatens to saturate or overwhelm health care capacity. By slowing the speed of spread, school closure can also buy some time as countries intensify preparedness measures or build up supplies of vaccines, antiviral drugs, and other interventions.”

Swine flu is coming: 10 things you should know

Since April, 2009, the swine flu epidemic has made more than 1 million Americans sick and killed 500, as reported by the Associated Press.

According to a White House report, about 30-50% of the population has the potential to catch swine flu and anywhere from 30,000-90,000 could die.

So, what can you do need to know about swine flu and your health? Here are 10 tips to support your immune system this fall.

1. Don’t panic.
2. The swine flu virus is “tougher” on some. (Children younger than two, pregnant women, people with health problems like asthma and diabetes, and young adults are more vulnerable to swine flu.)
3. Wash your hands.
4. Vaccinate your kids.
5. Get your flu shots early.
6. Be patient. Immunity takes a while to “kick in.”
7. Vaccines are being tested in eight cities around the country.
8. If an outbreak occurs, stay away from heavily populated areas, like the mall, and keep your hands away from your eyes, nose, and mouth.
9. Pay attention to your body and seek proper medical attention.
10. Swine flu and pork, a myth! (Swine flu is not actually spreading from meat.)

Herbs for use with swine flu H1N1

By Scott Stuart, ACHS Faculty

While offering no guarantees, vitamin D may help keep the swine flu away because it plays a critical role in enabling the immune system to successfully defeat viruses of all kinds. One 2006 study hit headlines when it concluded that vitamin D is effective in fighting standard influenza strains.

Elderberry syrup, or sambucol, a standardized extract of elderberry, has been shown by repeated scientific studies to fight standard strains of influenza. Elderberry appears to reduce the duration of colds and flu by several days. Other studies have shown elderberry syrup to be effective in fighting H5N1 bird flu, which is one of the core components of the swine flu pandemic's biology. Laboratory trials have confirmed that elderberry extract effectively defeats H5N1 avian flu with up to 99% efficacy.

Another ingredient they offer is selenium. In vitro studies confirmed that selenium, like elderberry syrup, can effectively fight the H5N1 strain of avian flu, making it a potentially important supplement for preventing a swine flu pandemic.

Other herbs they say may help include echinacea, goldenseal, zinc, and vitamin C.

DIGESTION
Some say that the flu “begins in the gut and ends in the gut.” This means that if you have good digestion, you will increase your resistance to this and other flu strains. Take a probiotic daily. Live probiotics are available in natural food stores, and probiotics are now more widely available in grocery stores, such as in yogurt culture and even in chocolate.

HOMEOPATHY
The homeopathic remedy Anas Barbariae is made from the liver of migrating geese. Because they travel the world, they build immunity to many viruses years before humans do. Be sure to get the 2009 version by checking the expiration date. In addition, the remedy Ferrum phos is effective in treating the early stages of the flu when used within the first 24 hours, and the remedy Influenzinum can be taken as a prophylaxis. This remedy is made from the same disease strain as the CDC uses to make each season’s flu vaccine.

LIFESTYLE ADVICE
1. Get Plenty of Sleep. To improve your resistance to any disease, the most important thing you can do is get enough rest. Your body knows how to heal, and it does this best when sleeping. Get adequate rest on a daily basis, and if you begin to feel fatigue during a time of increased stress to your immune system, take naps, get into bed earlier, relax and let your body do what it does best: restore and rebuild.

2. Hydrate. Our bodies are 80% water. Drink plenty of water each day to stay hydrated and to allow the body to flush toxins from the blood and the liver. Drink pure water, not soda or juice, for best results.

3. Exercise. Exercise increases your resistance to disease. It stimulates the cleansing blood flow and increases your natural stress reducing hormones. Exercise doesn’t have to be strenuous to be beneficial. Science has shown that walking daily is good for your health and well-being.

4. Spend time outdoors. The healing benefits of nature are yours and all you need to do is step outside. The fresh air cleanses your lungs and the vitamin D from sunshine is great for general health. Even on a rainy day or at night, the fresh air is beneficial.

Swine flu false claims infecting supplement industry

Swine flu false claims are starting to infect the supplement industry. What is the long-term effect of irresponsible marketing, products claiming to "cure" swine flu? Read this blog post by the Nutrition Business Journal for more information:

"The FDA is bracing for an onslaught of dietary supplements and other products making false or misleading claims for the H1N1, or swine flu, virus. A quick Internet search found that a number of U.S. companies are currently touting products they say can prevent or cure the H1N1 virus. In an effort to get out in front of what could be a public relations nightmare and provide fuel for tighter supplement regulation in the future, a coalition of supplement industry trade associations issued a statement today urging supplement manufacturers and retailers to “refuse to stock or sell any supplements that are presented as treating or curing swine flu” and to “refrain from promoting any dietary supplement as a cure or treatment for swine flu.”

"The groups backing the statement are the American Herbal Products Association, the Consumer Healthcare Products Association, the Council for Responsible Nutrition and the Natural Products Association. In their statement, the groups also noted that “federal law does not allow dietary supplements to claim to treat any diseases, including swine flu” and that they are “unaware of any scientific data supporting the use of dietary supplements to treat swine flu.”

"The statement did note that “there are dietary supplements that have much to offer in terms of enhancing general immune function. However, therapies for the treatment of swine flu should only be recommended by qualified healthcare professionals or public health authorities.”

"Given mounting public anxiety in the United States and beyond over the fast-spreading H1N1 virus, the associations’ action is an important step in encouraging the supplement industry to act responsibly and legally in the face of a potential health crisis. Let’s just hope companies heed their warning rather than put the industry in jeopardy by attempting to milk profits from public fear."

Swine Flu--What does it mean for your health?

This week there has emerged a new influenza A virus in Mexico which can be spread from person to person by contact. The virus contains genetic material from four different flu viruses – North American swine influenza, North American avian influenza, human influenza, and swine influenza virus typically found in Asia and Europe swine virus, a bird virus and a human virus. (Sharing of genetic material between viruses is common). The virus seems to have originated in Mexico and has spread throughout the country quickly, as well as to the US Europe and New Zealand. All the confirmed cases seem to have contacted the virus while traveling in Mexico and then brought it back to their country of origin. The first US cases occurred on April 17, 2009, in two children who resided in adjacent counties in southern California.

Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza virus that regularly causes outbreaks of influenza in pigs. Like all influenza viruses, swine flu viruses change constantly. Pigs can be infected by avian influenza and human influenza viruses as well as swine influenza viruses. At this time, there are four main influenza type A virus subtypes that have been isolated in pigs: H1N1, H1N2, H3N2, and H3N1. However, most of the recently isolated influenza viruses from pigs have been H1N1 viruses. The H1N1 swine flu viruses are antigenically very different from human influenza A H1N1 viruses and, therefore, vaccines for human seasonal flu would not provide protection from H1N1 swine flu viruses.

Since this is therefore a novel virus for human immune systems, we don’t have much natural immunity, thus allowing the virus to spread quickly. This is why there is worldwide concern over the possibility of this becoming a pandemic (A pandemic (from Greek pan all + demos people) is an epidemic of infectious disease that spreads through populations across a large region; for instance a continent, or even worldwide.( http://en.wikipedia.org/wiki/Pandemic).
